Hi all,

Recently bought a cheap zontes tiger 125, my first bike. I understand a lot of people aren't keen on Chinese bikes, but I just wanted something cheap geared bike to practice on for a few months before I do my license. Also using this opportunity to get familiar with working on them. Onto the problem...

When I got the bike, it was starting up, then once it was warm to was idling high at 4k revs. So I adjusted the idle screw down, and I can get it down to just above 2k (if it's warmed...

Hi I have a Honda cbf 125 2009 and the front lights are not working I have checked the fuses and replaced the main wiring loom and the light wiring loom and replaced the bulbs please help and the dashboard lights and back lights

Hi everyone,

I am totally new to all this so please have patience. Always wanted a bike but never known anyone who could teach me the ways. Took my CBT and on advice of instructor went with a twist and go to build some confidence. Having little experience i went for a Lexmoto Titan from a dealer and though its been great to learn on (ill be re-doing CBT on a geared bike and upgrading next year) i just seem to have problems. Been to garage 4 times this year and told nothing wrong but i can hear...

I noticed the voltage on my battery has been a bit low recently. Often sitting about 11.8V when I get off the bike. My voltmeter is under the seat so I cant check it during a ride, the only thing I can see is the battery saver led on my heated grips flashing sometimes and not others.

So I ordered a new battery from Tayna and somehow ordered the wrong one. It's 20mm too tall. Ive no idea how I've done it but I'm going to sort out a replacement that fits today for delivery tomorrow. I had to...

Not completely bike related, having a few glitches with car oil pressure so been checking what oils I can use etc... and stepping it up a grade.

But got me thinking about oil weights, as everyone knows modern oils have a cold/hot rating e.g. 10w40 is SAE10 equivelent when cold and SAE40 when hot. So when it is cold it acts like a thinner oil yet whenever we do an oil change first thing we do is 'warm it up so it comes out easier'.

Surely the oil is designed to be thinner when cold so would...

Morning All,

After rebuilding my front calipers, I now have a odd lever feel.

The seals are square for this particular bike and fit in an angled groove, so they are installed right. There is no air in the system, which was my initial concern, as the local bike shop bled the system for me to confirm. And the master cylinder feels right, as in the lever doesn't sink to the bar. The pistons move freely, moving forward and back, and will push in happily by hand. I cant see that there are any...

Hi folks, Bought myself a Zontes Monster in February of this year. It was basically brand new, the original owner had won it in a raffle and it sat in his garage for a couple of months as he was a non biker. Anyway, I bought it for a very fair price and have been pottering about in it over the past few months.
I actually posted about my experiences of it so far in another post started by 'secretagentmole' in a review of his 4 year old Monster.
My reason for posting is that I have just realised...

hi, I've just bought a second hand zontes tiger 125 2014 and I've noticed that one of the bulbs behind the rev counter has blown. Anyone replaced these before and could run me through it? and also a good place to buy replacement bulbs? thanks!

Hi,
This is my first post! Just need some advice, I have a kawasaki zx7r 2001 all the sliders on the carburetors go up with an equal amount of pressure bar one which just flys up with no pressure when manually lifting it. On revs 1 2 and 3 lift good but 4 Doesn't move, when inspecting the diaphragm doesn't sit in the seat and actually looks smaller or needs stretching to sit properly which I can't do does anyone know where I can get a new one or second hand? Any advice on a dyno kit would be...

So I’m cleaning the carbs up for the Trophy, I’m ditching the old air box and tubes contraption and gonna put on foam filters.
The air box inlet side of the carbs are oval with a separate small chamber - what’s it for?
It seems to divert air into to the carb top.
Please see pic.

I’ve polished up one of the float bowls and sprayed with 3 coats of petrol resistant lacquer...... I then picked up the carb and thought ‘WTF have I done???’ There is no...

Hey all,

I know that ultimately this is a 'if you want to' kind of thing, but was wondering what others may think about this?

Basically after my bike not starting and needing to charge my battery - I found I couldn't full take off the side panel
to get at the battery, one of the bolts is stripped (I think is the correct word)? Couldn't get an allen key/screwdriver
in to actually undo it.
Luckily I was able to kind of rotate the panel to reveal the battery - but this is not ideal in the...

Hi can anybody help? I have no spark and engine management light error code 19?

I am in the process of adding a cafe racer rear hoop to my CG125.
I was wondering if anyone had any ideas on where to mount the rear light/brake light?
It is the same style as the one below:

Any ideas would be helpful, I could bolt it directly to the rear hoop but I dont know how neat this would look :D

Thanks!

can anyone tell me a decent place to get brake pistons from,the rear ones on my victory hammer have seen better days,i can get the caliper repair seals
,the piston bores in the calipers are fine no scratches or nicks,just want to do a decent refurb on the brakes

Electrical stuff is just magic to me. I really can't get my head around it. Can someone assist? I have an Optimate lead fitted to the bike's battery. I currently run my heated gloves from it. I'd like to be able to run the gloves at the same time as charging my phone. Can I buy an sae splitter to have 2 sae sockets, then the gloves from one and the phone from another? I mean obviously the bits exist for me to do that, but will the battery stand it and put out the necessary power? And would it...

hi
looking for help with my scooter,when taking off its lagging but once its at speed say 20 to 30mph
its had new carb new spark plug an leads,was happening before new parts too
any one help

Currently my garage has a dusty old concrete floor so I was thinking of getting some self leveling compound to create a smooth surface, then painting it. Anyone else tried this? anyone recommend stuff to use? or should i get someone in who knows what they are doing?? lol

Hey everyone, doing a rebuild on a Stomp 125 pitbike just for a bit of fun and something to do on the nights when I'm bored! Before I started the project I had a quick ride around outside the garage and noticed something odd. The bike would ride mint, however when I wanted to give it some and got passed around 1/2 throttle in 1st gear, it almost felt like I was hitting a rev limiter and the bike would just scream but not move until I shifted up to second if that makes sense? I'm wondering if...

Evening, does anyone know of any bike that has a manual petrol tap that has ON , RES and most importantly OFF that is NOT attached directly to the tank but is bolted to the frame . I've already found one off a DR 800 , see pic . Any others ? Cheers.

Hey everyone! Recently i have got my hands on a Motorhispania RX50R, and so far she runs alright, overall nice looking bike. Its just not enough for me , so and idea upon my recent findings sprung up. There is also a 125cc version aparently , first of all sorry for the noob questions since i am very new to this forum and just wanted to ask if at all, is it possible to fit the 125 engine , or will it be a complete nightmare and forget about it. Also im asking this stuff because it seems this...

Hi folks,

So, put the bike in the dealership for a new tyre, and the health check that they do pointed out I had leaking fork seals. Obviously with the price difference, and generally doing maintenance myself I put new seals in.

Now, the next bit will sound odd.

Because I didn't really look at the forms when they were bad because diagnosis came from the garage, I am not entirely sure what bad seals look like. So, this also means that I don't know if the new seals are working or not....

So ... I’m stripping the carbs of the Trophy to give them a good clean and maybe some jetting work to suit a freer flowing inlet and exhaust.

Why do we complain that the fixings are made of cheese when they churn up and slip .... only to complain that they are hard as iron when we try and slot them with a junior hacksaw???

Eventually used the Dremel to cut a slot and remove the bast*rd, only 6 more to go.

Hi all, think I know the problem but after a second opinion. Got a lexmoto arrow which now it is cold takes a while to start up on the electric starter. If I use the kicks start it always jumps in to life after a couple of goes. I now only ride a total of 6 miles to and from work so I don't think that the battery is getting enough charge on a short run. I am thinking it's time for a battery optimiser/ charger. The battery was new in May this year.
Any advice welcome.

I want to swap a 1979 cb250 (super dream) engine in to my 1996 ca125 (rebel). The engines look almost identical, my question is, will it fit?

Mornin' all !

So, finally actually rode my bike. Was a dream. However, I do need to sort a couple of things.

The bike has only one mirror, which I can't see anything with. I'm quite broad so I basically cover the mirror.
It would be quite nice to see cars behind me, with the current mirror I could see the tip of 3 cars back, if that.
I have found on eBay these mirrors which are listed as for the XL124V.

HOWEVER - after trying to get it into the ridehide last night (currently not bolted...

I finally got round to switching over my number plate. It was supplied with long screws and screw caps, not only do I find the sight of long screws pointing at my tyre out the back of the plate irsksome but there’s no way they’re going to stay put, they go through the plate and the much larger plate holder holes with nothing for the screw to anchor to.
So I need some small and short in length nuts n bolts.

Question- If I used a 4mm screw bit do I need 4mm bolts and if so where might I find...

My 2008 Kawasaki Er6n has developed a little issue. The dash lights and the headlight on high beam flicker during normal running. If I use the throttle, the dash lights go back to normal. The headlight will get brighter, if I slightly pull the front brake.

The only thing I've done as a modification, is to fit heated grips and these have been on for over a month and function normally.

The other issue I have for the last 2 days, is the ABS light flashes and will then eventually stay on, the ABS...

I've had a search but can't find any tips, so apologies if it's been covered before.

After getting tyres fitted and re- balanced, the sticky tape used to hold the previous balance weights is left on the wheel and looks unsightly. What can I use to remove this sticky tape / glue ?

PS - WD40 hasn't worked ! :(

Can anyone point me in the direction of the correct torque value for the oil filter bolt on a 1994 Triumph Trophy 1200 ?
It’s not in the Haynes manu, which seems a bit of a basic omission.

Also in trying to find out, I’ve come across a post that says the 22mm oil drain plug should be tightened to 48Nm and that the 28Nm referred to in the Haynes manual is for the 14mm plug used on some models .... is this true or am I gonna end up with a stripped thread?

Thanks.

Looking to treat yourself to an early Xmas pressie or for Simone special?
This is good kit with a good rep.

Just got this in an email .. bargain 👍

Ive accidentally melted some plastic onto the exhaust. Forgot I had heated insoles and glove liners plugged in so they unplugged themselves when I got off the bike and because I was at a petrol station didn't step away from the bike- cue dangly wire coating melting onto the exhaust. Idiot.

So Ive had a google and am thinking this is the solution (except they don't sell that particular product in this country), what do you think? Do it or steer clear?

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

Nige....

Saw this clip on a facebook group i'm part of and thought I'd share on here :)

I don't use me bike at night at all .. last night was the 1st in many months .. well the last time I used the lights the headlight bulb poped .so i fitted a new bulb . Then many months down the line (last night ) I went to pick up my son from his m8s so I used the bike .well about 20 to 30 mins in to the ride it went dark. With the street lights it was bit hard to see then went in to 60 zone no street light and.it.was.pitch black in front me so I put full beam on then for the next hour pissed...

this has got to be one of the best descriptions I have seen of how a carb works

Over the the weekend i changed the staring motorbrushies on my CB750 .. .. as they was sticking .. . Push the starter and nothing happend so used a wee hammer to tap the starter while pushing the starter button . And the bike started .. So i was told its the brushies.. So taken them out .and one side it almost gone ...while the other side looks new .
. So swapped them over nothing... even hitting the starting motor with a hammer and pushing the starter button .
So swapped the new for old ....

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...

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...

I have just sprayed the wheels on my CG125 matt black and now need to fit new tyres and inner tubes :shock:
I have bought the below set of tyre levers from eBay:

Does anyone have any tips or tricks to make it easier? Or not scratch my wheels too much!

Thanks :thumb:

Pull up a chair as I tell a tale of woe.

I came to use my bike this Thursday and found there was no power at all. This is related as in my quest to fix this I drained my tank and removed it. After I pinned down and fixed the power issue I replaced the tank.

When I came to fill it up however it began leaking fuel out of the overflow pipe. I have no idea why this is, as the carburettor was in perfect working order before and was not even touched during my repair.

I know the go to would be...

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

Has anyone fitted a 150cc kit to a CG125?
I have been looking at doing the same, there are a few different kits floating around online/eBay like the below:

Do they require much modification? Or are they pretty much plug and play? I have read online about people having to enlarge open the crankcase with a dremel etc.

I would be fitting it to a 1999 CG125 :D

Hey all,

Im thinking of re positioning my ignition switch. ive checked my wiring and its a 5 wire on/off switch. will any motorbike on/off 5 wire switch work?

Some scum has broken the left hand side panel off the bike and taken the ECU.

Unbelievable - why oh why do I still live around London?

Anyway, mine is a 2012 model, and there are several on Ebay of different ages. Does anyone know anything about compatibility?

Presently I'm not working, and so I don't want to waste money buying the wrong one.

Someone else posted a similar story a couple of months ago on TMBF, is this just a coincidence?

Thanks in advance.

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 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
