Hi All

I have a Bandit 1200 engine which is in an Autograss car and the clutch won't disengage.

its on a hydraulic master and slave and it appears the clutch plates won't separate when the clutch pedal is pushed.

The system is bled and the push rod moves but the clutch is solid.

Any ideas as to how I can break the plates free without taking it apart, as there is a rollcage bar in the way.

Cheers

Hi I’ve gone and dropped my new scooter and scratched the front faring on both sides and the front mudguard does anyone know if I can get replacement parts to make it as good as new again

I am currently in the process of building a CG125 the wiring is an absolute mess! So I am looking to build a completely new wiring loom.
I will be replacing the battery with a capacitor as it is a kick start only model and the bike will only be used occasionally. I have thrown together this quick wiring diagram in Microsoft paint (I apologise for the crudeness of it!) Can someone please have a look and see if they can see any problems?
Thanks in advance

Hi everyone, I have an odd issue where I can measure 11 volts across the plug for the auto choke when the unit is disconnected, but when I connect it the voltage disappears. I've tested the auto choke direct to the battery and it works fine.

There seems to be an issue on the ground side. The 'negative' wire (grey) goes to the CDI, and the CDI then has a separate wire to ground (blue).

With the auto choke connected, I can measure voltage between positive on the choke, and blue on the CDI, but...

Well, that sucks...get a new bike and it has a fault in first 11 days. FI light came on, 1 long pulse, 8 short...indicating a faulty CMP sensor.
ANyone know where it is on the bike? I know the bike is still under a warranty but they don't cover getting the bike to them, if it's cheaper to do it myself than pay for bike to be transported then I'd rather do that!

Can anyone suggest the best way to confirm that a liquid cooled bike has a blown cylinder head gasket ? The bike is an ER5, but thankfully it isn't mine . My current thinking is that combustion gasses are pressurising the cooling system which is causing coolant to spew out of the reservoir overflow. BUT , I haven't actually seen the bike yet so it might just be connected up all wrong . Thoughts welcome.

Hi all,

First time poster.

Have just bought a CBR 125 2011 model as a cheap run around.

Got it through the MOT on Monday and one of the advisory items was indicators flashing too fast.

I've bought a new flasher unit/indicator relay. Does anyone know the location of it on this model? I've heard conflicting stories of it being behind the rear fairing and behind the speedo unit. Would like to be certain before I start taking bits off.

Any help would be much appreciated.

Many thanks.

Iv’e just bought a bike as a tiny project and it doesn’t have any pressure in the front brakes at all.
I took the Calipers of the forks and pushed the pistons back into posistion; put back onto the bike and hooked up a one way brake valve kit.

When attempting to bleed them no amount of pumps will release any fluid from the nipple although a small amount did come out when first loosening it.

Any ideas?

Winter is coming (if that matters) what do you folks recommend?
Having crossed over from pedal cycling I'm surprised that it isn't considered a big deal by motorcyclists. Those guys are always on about how many watts are lost in a chain at 30MPH, cleaning and which lube. Surly the potential losses are much greater on a motorcycle with greater speeds and miles.

Hi guys,
I'm just starting a new project on a 1991 Suzuki GSX600F. The ht lead has come of the ignition coil, is this fixable or do I need a new coil?

Cheers,

Hi, I'm new to this bike world and don't have much experience. I have an 07 ybr125 that's been sitting unused for about two years. Now I want to ride it but can't get it to start. I've tried new battery, new sparkplug, even the kick start won't work. I squirted in some fuel into the spark plug hole and it started up so I know it's at least sparking. I got a new fuel filter, clean the carb and all jets, they looked fine and it was quite clean inside. I drained it all and put in new fuel ,still...

Hi guys, first of all sorry if this has already been answered but I have tried searching for my issue and I'm not having any look so here I go.

Bought a WR125X last week 66 plate with only 4.5k miles, the bike is in good condition and runs smoothly. The other day I pulled up at a roundabout and I was waiting for the traffic to clear when some guy bumped into me (only visual dmg was license plate holder was broke) and I only mean a little bump as I was only nudged forward a foot at the most....

Over the last few weeks iv been doing some wee jobs on my bike so I decided to spruce up the paint work/plastics . So I stripped all the old stickers off sanded the lot down to a nice smooth finish . Filled all the dents. scratches . Chips . In . Then used the orange primer which you almost sand all it off .. So I buys 4 cans of the same colour .. Satin black.. So paints the side plastics ..back plastics .tank . And front mud guard .. after 4 coats 24 hour gaps to dry outright. Then puts the...

Hello all, I was doing max speed (not that fast) down the road the other day on my Yamaha ybr 125 2005 when i noticed i was losing power gradually. I let go of the throttle to see if it would sort it's self out and it seemed to stop losing power. So I hit the throttle again and lost all power, the bike eventually ground to a halt and wouldn't start again. I was told it could be a fuel line issue, could anyone offer any advice as to what the possible causes could be. Thanks in advance for your...

Hi, so... sidelight, fullbeam, rear light and dash light have all cut out after a fall (landed left side) i have been trying to fix this problem for the past couple of weeks and I'm at a loose end

Have replaced stator and regulator rectifier, and diagnosed the wiring according to haynes... all google searches lead to posts of others having the same issue but nobody ever actually confirming how or if they fixed it... i need this bike in full working order ASAP... HELP!!! 😂😂

Hi All.

I have a CBF600 sa8 (2008), and it is fitted with Honda's HISS immobiliser system.

My query is about the light on the instrument panel and it's function.
I only bought the bike 3 weeks ago, and I am sure the HISS light flashed when the ignition was off, indicating the presence of an immobiliser on the bike, but I noticed today it is no longer doing so.
The system seems to be working correctly when the key is inserted and the ignition turned on - the light comes on for 2 seconds then...

Hi everyone im new here i have a f650gs i recently took it for an mot all was fine til he tested the indicators which had previously been fine.
So he flicked the indicator switch to test and all the dash lights indicator lights and bot brake lights stopped working i have replaced all the fuses with brand new ones but still nothing any help plz Glyn

Or how to knacker up a cheap but perfectly usable electric sander.

So I was browsing the web for some info and found a vid of a guy who had created a DIY parts tumbler.

Following ( kind of ) his lead I screwed an old sweet tin to the plate of my sander, held the sander in a vice, put some cat litter in the tin along with a few fixings I need to clean up prior to plating , put the lid on and taped it shut.

Switched the sander on and it all started vibrating like a goodun.
I watched it for...

I was searching on eBay and I happened upon this company that sells a big range of stainless bolts and studs mainly for bikes . Their prices seem very reasonable compared to others that I have seen . This is from Seller's other items so everything you see is from the same company.

Hello all,

I’m after some advice for a fault I have on my CBR600RR 2004.

I use the bike as a track bike only and during my last trackday the cooling fan wasn’t coming on. The temperature was showing up to 110 degC on the dash.

When back home I carried out diagnosis procedure stated in my Haynes Manual, and couldn’t get to a root cause. Fan is ok, relay is ok, continuity fine, getting 12v to relay switch side. Just not getting the signal from ECM to come on.

The bike started before doing all...

I need to strip apart the forks on the Trophy, apparently this requires a 30mm external AF drive on the end of a long bar to remove the damping rod.
I do not possess such a thing or do I possess anything with a 30mm external hex.
Anyone got any ( sensible) ideas?
Ta.

I need one of these

But it says it is out of stock. I have previously explained I am an idiot with mending so asking for advice.

Fitted a new lithium battery to the bike. After 3 days the bike is flat. Battery charges using a lithium specific charger and Im ok for another few days. It was working fine with the gel battery. Any advice please on what it could be?

'Sup dudes.

I had a little unplanned dismount some years ago and busted my fairing. I replaced it with a Chinese number but have recently got hold of the final OEM panel to complete the original (nearly).

I couldn't find a decent rear pod thing so am going to have a go at repairing the old one.

Here it is:

I have seen plastic expansion tanks on all kinds of engines from contractors plant to bikes over the years. What I could never understand is how the coolant gets back into the rad after the spring cap has opened and lets the hot water out. If it never needs to be put back why the tank?
My Honda scooter has this set up, The plastic tank is the only way I can put coolant into the system as the rad cap is hidden under the bodywork. I cant see the point topping this low pressure tank up if it cant...

Which would you go for :)

Hi again,

SYM Jet 4 125cc Scooter

Recently, say the last 3 days riding my scooter I've felt my back end slipping/sliding mainly when turning corners. Now I don't ride at high speeds and have always slowed down when turning corners and this has never happened to me before.

It feels really weird and scary at times as I can feel the back end slip which makes my heart jump as it feels like the back end of the scooter its about to slip and give me a closer look at the tarmac...if you know what I...

Hello there

I am new here and to bike so please be nice :)

I Have a Suzuki DR125 SM 2010 and the bike wont start, It ran once but wouldn't idle so as soon as I let go of the throttle it cut out.
The FI light is on and I have checked the clutch switch and the side stand switch both been bridged and still the light stays on.

I hope some of you here could help or point me in some sort of a direction.

Thank You

Smurfyy

Hi,

For the last 3-4 days when I finish riding my scooter (Sym Jet 4 125cc) and turn the engine off I've heard a weird sort of clunk sound when the engine turns off. The first time I heard it I thought something had fallen off my bike but didn't see anything and thought nothing of it but it now happens every time I switch off the engine.

This hasn't happened before now and not sure how to describe the sound, its like 2 bits of metal knocking against each other.

Scenario just be clear is I...

I have been all over google and YouTube looking for assistance with no luck. I have found some videos that mention plugs and then they seem to be miraculously removed. I have done 2 and 3. But can’t physically see how to get 1 and 4 out. The Haynes manual is next to useless as ever. It looks like I have to take loads of extra bits of to be able to get the coil out. I have undone the water pump which helped with two. Any help would be my appreciated.

The previous owner of my ER6F had the preload set as per the picture. Looking at the manual I think it's at the highest setting.

I've tried adjusting it using the spanner in the bike's toolkit but it won't shift in either direction. Any tips?

I've bought a converter cable that adapts the old style optimate tm plug to the new sae plug. As it connects to the end of the existing lead, which is permanently exposed but usually sealed with a waterproof cap, I'm wondering if I need to do something to weatherproof this new connection. Its the white connectors shown at the bottom of this pic: 38070167.jpg

Do I need to get some heatshrink or sheathing over it, or cover it in tape? Its going to be a permanent fixture. The connection is good...

Good morning All.

I am hoping someone could enlighten me on how to wire up my heated grips through a Live Feed to the ignition.

Now I will be honest that entire sentance may as well be in mandarin for all i understand about electrics.

I know that this little in-offensive live wire has to be fitted in the fuse box, but where? These are R&G Heated Grips and have an inline fuse built in.

I have a Suzuki Gz 125 Maurauder 2009.

Any help or advice would be much appreciated.

And yes i've read...

I don't intend to not ride my bike over winter,but I'm not going to be riding if its snow or very icy. So it could be away for a day or a week or more.
My cbf came with an optimate cable.
Do I need to get a corresponding charger?

I have had a long standing problem with my 2006 (22K miles) Z750 where the clutch grabs when cold. Once the bike has warmed up the action is much better. I have had two mechanics look at it and both have changed the clutch plates to no effect (the last set being replaced about 1500 miles ago). I have also changed the oil recently (MOTUL 5100 10W40 MA2 SEMI SYNTHETIC) again without effect. I have played around with the clutch cable adjustment again failing to stop the problem.

The symptoms I am...

Hi every one . Here's a question to the seasoned riders . Last year I had a new BT21 battlax tyer put on my bike (CB750FN2).. so now iv checked it and its almost touching the small MAX death tread . And it's starting to go flat on the crest of the tyer . Its done 6500 miles mostly on motorway an two up .so I say 4K motorway two up .. so is that good for a back tyer on a 750 ... the tyer are sports /tourers . If anyone can let me know if there is a better tyer I'll happy to try. Thanks

Hello!
I am currently trying to get my girlfriends 2006 cg125 started so I can take it for a MOT

Its been stood for over a year
Replaced battery

Turn the ignition on and everything works on left handlebar control.. headlights, horn, indicator

Rear brake switch works too

However the right hand side handlebar control nothing works.. starter and front brake light switch.
Push starter motor and nothing happens.. no relay click or fuel pump noises.

Any thoughts on solution?
Thanks :)

I have 10 Dowty washers ( rubber with metal inserts ) that fit under the cam cover bolts on the Trophy.
They were caked in a hard residue that I reckon was limescale, replacements are about £5 each.
After a bit of research I created a mixture of white wine vinegar and lemon juice & left the washers to stew over night.
This morning most of the lime scale had disappeared and what was left could be easily scraped out of the grooves with a cocktail stick.
Rinsed and dried - job done 👍
Saved myself...

Hi Guys, i need help in restricting my lexmoto hunter to 30mph, the previous owner told me that he changed the cdi and exhaust on it to make it faster, I on the other hand dont want to but need it restricted :cry:. The problem is that i bought a new standard cdi for the bike, but it still does over 30mph. I cant restrict it in the throttle as its a geared bike, will it help if i buy a new exhaust that is restricted? Any other ways in which i can restrict it? Thanks in advance

just got a new stator plate as a replacement for missing one for a 125 pit bike engine I've bought, all's well except it has a green wire which isn't connected to anything, it has its own grommet around it, could someone explain to me what this wire is for and if its to be connected to anything on bike or stator plate.

Hi, guys i managed to buy a lexmoto hunter yesterday. I rode it back home for 15 miles and when i got home i noticed an oil leak, it was coming from the stator casing. I took it off and there was oil there (not much) , im not sure if there is supposed to be oil as there is a screw from the top (as if to fill up) however there is also a hole on the bottom for liquids to escape (factory). Please help, also i wanted to change the oil in the engine and unscrewed one bolt from underneath the...

Ok, so my drive chain was really slack so I followed the manual instructions, loosened the brake pedal free play nut, the brake torque rod nut and the axle nut and then tightened the chain. As far as I can tell the rear wheel is aligned with the marks in the window being even. Then, as per the manual I tightened everything back up to within the manual specs.

But now, the arm that links the brake pedal to the brake lever doesn’t return properly - it sticks and the rear wheel is sticking to the...

Hi all, I have a Honda 125 Pantheon I am doing a few jobs for the MOT.
The rear adjustable shocker is seized. It is dry and working fine but cannot be adjusted is this a MOT fail? thanks John.

Part of me is wondering if it's for the best and I should just leave it be, because I want to keep a clean license.

Anyway, I have basically street-fightered a 93' ZZR600 because of several reasons.
1) It was ugly as hell
2) The paintwork and fairings were just such a horrible state
3) I want something that just runs and doesn't matter if I drop or bin it
4) I want to easily be able to work on it in the future without having to disassemble a mountain of plastic.

The forks were a disgrace and...

My bike is restricted to 33bhp by a throttle limiter and washers (I think) in the airbox (not sure what or where that is).

I think I can mange the throttle limiter, It looks like a bit of metal that is bolted onto the whatsit-gubbin at the business end of the throttle cable.

I've got the fitting instructions and was told that I'd just need to reverse them to de-restrict the bike. The trouble is that the instructions don't come with clear pictures (just little fuzzy photos) and they are...

Hey, sorry this is a bit long winded.
From the beginning, last year I had a Barnett spring clutch conversation and ebc heavy duty plates fitted.
Everything was fine up until a few weeks back when the clutch started binding and I was struggling to get neutral while she was running.
After lots of googling I pulled the clutch, turns out the wire clip that holds the rear two plates back had come out at one end and was hanging about between a steel and friction plate.
I refitted it, done an oil...

okay so... my piaggio fly 100 was recently stolen and recovered. The thieves hotwired the bike and cut the ignition wires, I know that it’s the red and white that start it but what are the black and green wires? Also they took the battery for the bike so none of the electrics or lights work. The bike does have a kickstart but it doesn’t spring back up as it is old. I’ve tried to put the red and white wires together and kickstart it but it just won’t have it no signs of life atall. I have put...

I've seen some crash bungs on eBay, they are listed for a Kawasaki Er6F, it's the same year bike as mine, but mine is a Er6n (naked version). I've tried Google but can't see if they would fit and the seller is not sure, but thinks the frame is the same once the faring is off the bike.

Any ideas?
