ever since the starter clutch went on my bike ive lost power. I replaced the starter clutch and she cranked up 1st time. Idle seems ok but when i go through the gears it feels like its chugging along. when in top gear if i try to hit full throttle it starts to chug. Ive had the carbs cleaned just to be on the safe side as initially i could barely get 20 mph. now im hitting 55 mph but its still chugging. I will check the spark plugs and have ordered an engine compression test kit as well as only cheap Have also ordered a new fuel filted as i havent replaced that since ive had the bike ( 18 months ) but havent really done many miles. Any advice and tips will…

Hi i have a 1995 YAMAHA DT50 i have just replaced the fork seals but do have a manual. I was wondering if anyone knows how much oil to add to each fork? If anyone knows could they please contact me thank you.

Hi there so my ongoing project with the XTR has one thing left the front brake. When I got the bike the brake would build up pressure and then overnight would lose it again. I cant see any liquid dripping out of the caliper so i assumed that was ok and bought a master cylinder kit. Now my boy who the bike is for gets impatient and says let me take the bike into work and I'll get it fixed in my lunches. fast forward a month or two and it comes back to me with no work done at all but in the kit for the master cylinder there is now a ball bearing which I dont remember taking out of anywhere, is the ball a one way valve that I've overlooked. Ive checked the service manual and…

Hi, I have a question regarding the 250 US Custom. How do I check the oil level? I know where the filler cap is but I have no idea how to check the oil. I also have no idea how much oil it should have. If I had an instruction book that would be a start! As my name suggests I am a bit green when it comes to bikes and would appreciate any help or advice that I could get on this bike

hi all, just bought a yamaha 600s diversion N reg, so believe it's a 95 model. the bike is in superb condition and has only done a genuine 2800 miles from new. are there and geeks out there that can help me with an issue that has become very fustrating. the fuel overflow pipe that is split over the 4 carbs constantly leaks fuel over night. this does stop after a period of driving/ warmed up. i understand it's a vaccum system, so could it be a vacum pipe issue. the also appears to be a small square box type thing coming off the tank, have no idea what this is but that also leaks. the fuel system/ carbs had spent a month or so in a sonic bath so all clean …

Hello My Water pump on my 50cc aerox has been leaking for a while now not much a few drops now than then i was wondering if it is ok to drive untill i can get a new one. i just got a new spark plug for it as it kept dieing on me while driving to see if it sorts that problem out and i will be checking to see if it worked in the moring. can any one please help me on my waterpump problem

Okay, So I have a complete Stage6 set up literally everything in terms of CVT/Engine is all S6. I'm gonna tell you I have played with my carb which I regret but I'm not sure if that's the issue as the mixture screw only effects up to half throttle so I know my 21mm Dellor screw is fine. My Aerox is rapid up to half throttle , if I pull it anymore it slows down/losses power (don't like to say bogging as that is not really what it's doing) It's got open air filter with 92 main. Any ideas on why it's doing this? Fuel is fine, seals are fine compression test was great. Vacuum is fine. Thanks Guys!

Hey guys, does anyone know what the pipe in the image below is for? Also if I get a new exhaust what should I do with the hose connected to it? Thanks for reading

So I currently own a Yamaha Aerox R 2016 and was wondering after derestricting it, would it be a good idea to get a Yasuni R exhaust? Also would I need anything else or can I just literally put the exhaust straight on? Any help is appreciated George

Hi, I have a yamaha aerox YQ50, when i bought it, it has a standard exhaust on it, a few weeks later the exhaust blew and i had it replaced for a Leo Vince TT. Since then the bike has had a problem, when I slow down and get to around 5-10mph and accelerate again, the bike will bog down for about 20 seconds until it shoots off again, I have had the bike in the garage and the following had been checked: > Clutch and variation has been stripped, cleaned and checked > New rollers as the ones that came with my Leo Vince TT where not compatible with my bike > Throttle and Carb had been tuned and cleaned > The spark plug has been changed The mec…

Hi Guys, I've got a 31 year old TY175 which runs on mineral two stroke oil on the standard autolube system - the book says its about a 30:1 mix ratio. Does anyone know if I can swap over to fully synthetic oil on a leaner mix without harming the engine? I believe the oil/petrol ratio is adjusted by re shimming the pump? Cheers, Jim. p.s. will update my profile this weekend.

Hi - Can anyone please help? I am after a Certificate of Conformity for my 2005 Yamaha TDM900 in order to export to France. Should I be able to get one from Yamaha UK, free of charge? They have yet to respond to my email of yesterday. I hear that people seem to have some trouble getting these Certificates that in reality shouldn't be necessary as they originate in a European country... Many thanks for any help that anyone can give me. Jetty
