So recently my Raid developed these problems. I guess it is time for valve clearance adjustment/ shim replacement? - Lots of blue smoke when cold starting, hard to start after sitting for 10- 12 hours. My guess is the oil leaking into the piston during the night. - Loud clicking noise for 2-3 minutes af...

My 2004 Blue TTR250 has sat for a while not being used. Wouldn't start at all, but turned over fine, so I stripped & cleaned the carb. Turned out the float valve was sticking closed, not letting any fuel in. All cleaned up with carb cleaner, then I put it all back together & it started reluctantly...

Good day everyone So I feel like my bike has reached a stage where I feel its necessary to spend some cash on it. I have a bit of spare cash lying around so here goes. When the bike is elevated the rear wheel seems to have some play when the wheel is moved up and down. No play when moved sideways. My uneducated...

Some of the older models such as the 4GY1 ran different teeth combinations to later engines. There was a 72T/20T (#4GY-15512-00-00) large idler gear which ran with a 16T/15T (part #4GY-15517-00-00) small idler gear. The large idler gear is no longer available from a Yamaha parts dealer in the UK alt...

Hi, I am usually pretty good at working out how long road tyres will last on bikes but I am still pretty new to this off road stuff. I have an Ac10 on the back of my TTR and it has about 10mm left on the centre blocks (it seems strange calling it tread). if I sort out some other issues with the bike I intend ridi...

eHelp my bike is making an ominous rattle. It sounds like the rear chain is knocking on the engine cases but it isn't because I have just put a new chain and sprockets (14/48) on. The noise seems to come mainly from the left side of the engine and originally seemed to only be when the bike was moving but n...

ITs dark out , so havent looked hard , but starter is cranking , battery has good charge , but wont fire. Is there a common fault electrically that would be causing the problem?

OK, so when the clutch is in all the way, no drag or anything, fully disengaged then slowly let it out and nothing till it hits a very narrow section of 15mm Lever is adjusted with about 5mm of play at the very end of the lever, so 75mm travel pulled fully in, clutch take-up begins at 30mm out and fully out at 4...

Hi everyone I am new to this site, I bought my ttr250 in February and rode it for about a month before doing a full strip down to it.

Hi, since buying my TTR back at the end of December it has had a misfire. Now it is always there but not constantly, for instance I rode it from Derby to South Wales a couple of weeks ago and it was okay at a steady 65ish in the pouring rain on the motorway but then was missing firing on the back lanes. I have p...

Hi all, I have done most of the maintenance tasks on my 2003 model TTR since I bought it last autumn. One thing I have not looked at yet is the cam-chain and tensioner and I was wondering if these tend to give trouble. Has anyone any advice before I go at this task? Thanks! APW
