Hi all - the indicator switch on my 2005 TTR is sticky - does not move freely left/right but does still work. Any tips on how to resolve before I start getting the tools out ? Many thanks

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

Hello guys. Lately it has been very difficult to downshift on my Raid. Upshifting is easy and smooth. However when i try to down shift, the lever just sticks there, and i have to step very hard on it to change the gear. This only happens when the engine is running. At 1st gear, even when I pull the clutch all...

Hi, I noticed from reading other posts that some people have fitted CO2s on their TTRs. I just wanted to check what sizes people fitted. I has some on my Serow and they were excellent but when I fitted the back one I had to change the sprocket size cos their was so little clearance. Thanks

Hello guys. A few days ago I changed the piston rings. When I put everything back together, the bike ran fine - the mechanical parts at least. However, the odometer refuses to turn on, and the left/right signals do not work. N indicator still work, as well as the head light. When I signal left/right, the...

The notorious stock Allen head bolts are known to be a PITA and strip easily. An excellent and easy replacement is the bolts that connect the fuel tank main bracket to the fuel tank (blue/plastic). They are exactly the same size, have a normal 8mm hex head, and have the same coating on them (phosphate?)...

A simple question. If I open the engine, what more pieces should I change? Including all the gaskets. If somebody can make me a list and where I can find them, it would be good. I have forgotten for many time this problem in my TTR and probably I should not forget it forever.

Any ideas how to get the chain puller off? It's the only good part left on this axle and for some reason costs twice as much as the nearly identical puller on the other side (WTF?!).

Anyone had this? When a mate's TTR gets hot (about 15 miles into a ride) a very loud screech starts in the clutch/gearbox area. The pitch changes as the gears are changed and it happens with the clutch fully engaged. I haven't heard it myself and was unable to replicate the noise when I took the TTR for a ru...
