i have to replace my forks after getting them all bent up in crash. got replacements, just need advice on how to jack it up/keep it up without it falling on me.

any good homemade diy ideas guys????

Does anyone know if I Can I fit a BA20D LED bulb to replace the very dim 35/35 existing one please?

Was just riding home and noticed people staring at at the bike from their cars, I looked down and there was big flames coming out the exhaust, every time I was stopping huge flames were coming out the exhausts

Changed my rear pads today and was struggling to get both cylinders back into the calliper flush. Only need a mm to get the calliper back over the disc so used two ring spanners to push the back a bit. Not excessive force by any means but one of the cylinders now has a small hole in it where the face of the cylinder has broken.

I've bought a whole new brembo calliper but it wont be here for a week, so my question is, how safe is the current one?

Tried it out and it still breaks, also no...

Hi Everyone

I have noticed recently a whistling that appears to be coming from the front brake, its very high pitched and although not particularly loud it is rather annoying.

At least I think its coming from the front brake, this is supported by the fact that when I pull the brake lever the noise stops.

Can anyone suggest where I might start looking to find and resolve or is it most likely something I can ignore (I'm guessing not if its concerning the brakes)

TIA

Hey guys, so I'm new here, I live in the Midlands and I ride a Lexmoto ZSX-F.

I love my bike, I bought it yesterday but it broke down.

So basically, it was working perfectly fine until about an hour in when I realized I was hitting 50 in fourth (funnily enough, even though it's a 125, I hit 60 in 4th at standard spec), anyway, I noticed I was slowing down and as I got to an island, I cut off, my dad came back to me and I got a recovery, the bike turns over but won't start.

We tried bumping...

Can anyone help with overhauling and maybe installing a 150cc bore kit onto an engine, thanks

Hi guys just tried to ride home and the bike goes into gear two then cuts out, popping from the exhaust and sounding off

Hi guys, yesterday had to tighten the carb screw because it wasn't idling right, after tightening it was running great, went back to it and now it won't fire, the spark plugs are working but they was covered in some type of black oil, any suggestions?

Hello, Can anyone point me to a good diagram showing the air mixture and fuel mixture screws on the carburettor of this model please. The book that I have on Chinese/Japenese 125cc motorcycles is as clear as mud and I have located one screw on the side (right side of bike) that adjusts idle speed or, is it air/fuel mixture?, but, have no idea if it is air or fuel and how one is supposed to adjust either?

Any help appreciated.

Been struggling to get the carb boots back over the carbs after having my airbox off.
Obviously with the bike being 28 years old the rubber is pretty dried out.
Is there any easy way to loosen or soften the rubber to get them back over.
Cant find any on ebay or wemoto to just buy new ones.
They are oval shaped aswell so cant just buy universal ones as most are round.
Cheers

My bike has suddenly started making a sound that I would describe as being like the buzz of high voltage electricity at around 6.5k revs. It starts just before that point, gets louder, but then disappears after. It does not seem to affect the bike though and is the same regardless of gear.

Does that make sense and suggest any likely cause? Will seek professional help next week, but just want to know if it is safe to ride tomorrow.

hello everybody. new to this so please bare with me.

i have a 2014 honda cbr125R. had this bike for about 6 months now and never had a single problem. Until yesterday that is.
I was riding home from work when a noticed a high pitched whistling noise coming from inside my fuel tank. naturally i went to the internet to try to diagnose this problem and all that i could find was about pressure realizing through the tank lid. so i set to test the theory by putting my spare key in the tank...

We have just brought my son a peugot xr6s on a 2094 plate. In the 2 weeks of riding we have lost the ability to auto start now jump starting. The battery went flat but its now charged so looks like jot holding charge. In addition is over heatng with the gurge getting to 100 !! And loosing power intermittently after hitting 6000 revs ( 35 mph) but waa derestriced by last owner?? Starting to wonder if it was although my son said he hit up to 60mph in the first week of riding abd felt a power band...

So I have a new Yuasa battery no order for the bike. I've got a cheap battery charger but have read this isn't appropriate for a first charge of the battery. A friend has lent me one of these

sealey autocharge 12. Will this be ok for a first charge of the battery to get it in top condition from the off?

thanks

Evening all,
Just wondering if anyone would know a rough price on getting a link pipe made up?
I cant seem to find one anyway for a 4-1 system for my bike due to the age of it.
Absolutley hate the end can thats on it but its attached to the link pipe and cant be removes so want to get a new can and pipe made up for it.
Just wondering if anyone has had it done and roughly how much?
My bike is a 1989 zx10
Thanks

For about 2 years, my CBF600, when starting cold in the morning, struggles a bit sometimes = would takes 2-3 tries before it starts. I thought that might be old spark plugs responsible, which I changed 2 days ago... and still exactly the same issue. Thus is not the spark plugs. Also if it does anything I had a year ago the carburators aligned, which also did not have any impact on the start issue. I just did a oil and filter change, still nothing different.

I am wondering... before I take it...

Took my lil old CG for it's mot today ,and it passed.
The last time it was done was in 2009 which was also the last time it was ridden. So thank you folks, I have never owned a bike before and certainly never worked on one, and with your help, and a lot of swearing cursing and bloody knuckles, it was brought back to life.
Thank you all. :D :D :D

My bike was travelling fine for 40 mins then all off a sudden, it was like i had lost power and the bike was kangarooing, lurching forward but only travelin at about 10 mph. It also seems too be going through the petrol quite quick.
Anyone have a clue what this is.
thanks

Hello everyone....My wife bought me a second hand moped for my fortieth birthday, as I could use it to get about the local area and leave her with the car, it was also a thank you for me running the family home whilst she was in hospital for three months last year, anyhow she was ripped off and the bike was not useable, I got a friend of ours to look at for me and he put running the best he could.

It lasted only a little while and yesterday the whole crank seized, I have sourced a replacement...

Hi, newbie here, just got my first bike a sinus hoodlum, love it but the headlight bulb is pretty poor tbh, is this easy to upgrade?

Hi all,

I recently posted about my bullit hunt 250 motorcycle where I had lost the keys.

I have since had the ignition barrel and new keys replaced and I thought that would be the last of my problems.

Well...

The bike will now not start! I have charged the battery, lights indicator brake lights all work fine. The start button turns over but the bike will not fire.

I read online that it could be to do with the stand switch but it won't fire even off the stand and I have tried disconnecting...

I was riding home in London and was going through the usual set of traffic lights, so it was constant stop start stop start... after 20 minutes of riding I tried to accelerate from a traffic light and the engine became really weak and instead of accelerating fast like it usually does, it done a stumbled acceleration. Then all of a sudden the engine became really weak and every time I tried to accelerate from traffic lights, I would pull the throttle all the way but it would hardly accelerate.....

Hi all seem to be having a problem with downshiftinh on my 1989 ZX10.
When going down the box sometimes im having to push the gear lever 2,3 sometimes 4 times to get it into gear.
Its fine going up the gears.
Any ideas what the problem could be?
Thanks in advance

Hi guys just notice this morning that my left indicators not working properly sometime it flash when i signal left sometime it doesnt, is there a fix to this? Thanks

Whenever i try to go into first from neutral the bike lurches forward, and then shuts off. The lights are still on and all electrics still work, but the bike just dies.

This is something that has recently started occuring with my nearly 10 year old Kawasaki KLE500. If I ride the bike in heavy rain, it sounds normal at first, then will suddenly sound weird. It's hard to describe other than the bike sounding far louder than it should be normally at a set gear. Maybe sounding a little bit more... 'rumbly' maybe? Yeah, not really a word but it's hard to describe.

The engine still works as normal, I still get the same power output out of it but the noise comes and...

Hi, so about a week ago I took my kawasaki kh 125 out to work and on the way back was hit by some heavy rain, ended up having to push the bike home as it stopped starting after a while, it would run for a bit then lose power and cut out and so on until it finally stopped for good. I found the problem( or so i thought) as some water had gotten into the fuel and into the carburetor so i drained the tank and cleaned the carb and put new fuel it, the bike still wouldnt start when I kick it over and...

My Yamaha RS125 blows out white smoke for the first few miles, then runs clean. I've noticed the gearbox oil level dropping, I've topped it up. Had a read around, seems it might be that one or the other crank seals has gone. The bike had been stood for a couple of years before I bought it, couple of weeks ago. The spark plug is black but not oily. From this description, does it sound like crank seals? If so is it more likely to the the left or right one? Could I tackle this job myself...

The exhaust baffle on my Yamaha RS125 has snapped, presumably when I previous owner tried to remove it for cleaning. I'll need to decoke the exhaust at some stage, want to weigh up the options. Obviously a new exhaust would be useful but they are very rare, as is the baffle. Would filling the silencer pipe with caustic soda or the like, baffle in, do the job? Any other ideas?

Cheers.

Hi guys, so I'm changing my chain, sprockets and crush drive rubbers on my 08 ybr 125 tomorrow. I ordered a DID chain and sprockets after a bit of research. I ordered it from eBay and it says it is for my bike. The instructions are veryisleading on fitting the chain. I think Ill be okay with the fitting of the chain if it is a straight swap, but what I'm not sure on is if it is going to be the right length or not. How would I check This? Would it be as simple as removing my old chain and lining...

I think I am going to take the plunge and ditch my Bridgestones for Michelin. Frankly they keep giving me unpredictable grip, including a front letting go at 20mph on a large roundabout on the Bristol ring road after I had been riding for an hour and a half. Dry as you like and nothing on the road, just what these tyre's have done to me, and the wet is nerve wracking.

I'm debating the Michelin Power 3 and the Pilot Road 4. Michelin marketing claims the Power 3 will give decent wet grip from...

Hi guys

Came out to find the bikes wheel facing straight and steering lock been forced round. Can't turn the key in the ignition now and I'm a bit stumped.

Any ideas? Bike is a 2008 Bandit 1250.

Thanks

Last night I was riding my kawasaki KH 125 in the rain, it began cutting out after a mile or so of riding and would splutter and completely stop like it was stalling. I'd then leave it for a second and it would start again and continue down the road only to do the same thing. It eventually cut out completely and wouldn't start again. It's still not starting today I have checked the spark plug is sparking and checked all of the ignition coil and system and couldn't see any signs of water damage,...

Hey folks

This could sound really daft and for that I apologise

But on a Yamaha xj6 is it possible to shift gears without using the clutch without damaging it and the gearbox? I was riding to work and as I was about to change gear normally lower throttle>depress clutch>go up a gear my fingers slipped of the clutch lever before I depressed it but still managed to change gear, I tried it a couple more times and it will allow me to go up or down gear as long as I'm not using the throttle, is...

Hey everyone, it's been awhile! Anyway despite having practically no money myself I've been able to start a new project bike! Well I'm building it with/for my dad so he's the one paying for everything :D . It's a 1980 CX500 deluxe, we bought it and 3/4 of a 1979 cx500 custom in parts. So got some extras and also missing a few things. Which brings me to the problem. I cannot find swing arm bearings that fit the bike properly! Now I'm pretty sure this isn't my lack of ability to fit a bearing in...

I'm a total newbie with some mechanical know how and I've just bought my first bike. I know most peoples opinion is avoid Chinese made but I've had no major issues with my wee bike so far.
The only one thing I've found is it simply refuses to engage neutral - unless the engine is turned off when it seems to have no problem at all.
When running it just skips through first to second and back to first no matter how gently or slowly you try to find neutral.

It is a huge pain in the ass when your...

I would like to thanks you all for helping me sort my clutch problem out. I had to wait for the stupid honda tool to remove the centrifugul oil filter. But i can at least get my gears now.
Im still having a few problems, possibly with timings, i can get the bite in gear, even get going, but i seem to get a bit of juddering when letting go of the clutch. But im going to take it in for a service and let them sort it out for me
Thanks all. :D

I bought a 1982 model 5 days ago. Did 100 miles or so with no problems. Over the last couple of days I've had problems with it:

It's OK from cold but after a mile or too the engine starts to bog down. You can't rev your way out of this and evetually the engine dies. If you leave it a minute or two it starts first kick then runs for half a mile or so before bogging down and dying again. Repeat several times.

The bike had stood for a couple of years, most likely with an empty tank. I can see...

on my loncin petrol pours out of the over flow pipe when left standing ,this may happen every week or a month between this happening I have stripped the carb down cleaned it out but it happened again today, if I forget to turn the petrol tap off when I park up , I could come back to a bike with a empty tank I will strip the carb again but what am I looking for that I missed

Hi guys ... I am off to Manchester tomorrow and decided to give the bike a quick once over today instead of weekend - oil, water light etc

I noticed the plastic water bottle a little low, not majorly, above the min line but no where near the max line. I decided to remove the radiator cap to top up as instructed on the internet! (assuming that's right) but the radiator appears to be full. I can feel the water if I put my finger in the hole. - come on guys stay on track here.

Now I am a little...

Hello All,

I'm completely new to motorbiking. I'd love to learn how to service and maintain my bike myself.

I appreciate there are manuals and online videos, etc but I tend to learn best in a more hands on way.

If there is anyone who would be willing to share their time and experience I'd be very grateful.

I'm based in Cheshire and am close to Manchester also.

Many Thanks,

Hi guys I've got a 2008 ybr 125 carb model which has had a replacement engine, which was injection but had a carb manifold to. I found out it should be idling at 1300 to 1400 rpm, mine is idling at 2000. It sounds fine, but if I adjust the idle to lower than 1900 it starts to struggle, but will still rev responsively. Is this something I shouldbworry about or is it ok to have my idle set at 1900 to 2000? A friend said that the rev counter isn't 100 percent accurete and it sounded fine, but I...
