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

Hello guys. Lately it has been very difficult to downshift on my Raid. Upshifting is easy and smooth.

At 1st gear, even when I pull the clutch all...

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).

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.
