It's THAT time of year again for my TTR.

Every year, in the UK, a vehicle has to be licenced (road fund) and if over 2 years 11 months and 30 days old it will need an MoT certificate. Together with insurance it all adds up! In order that my bike stands a reasonable chance of securing an MoT certi...

Hello all, I have got my bike jetted in and it runs great, but I can't help but to think of this tick. There is a slight tick audable from the motor at high RPM's, is this normal or should my valves be adjusted? I would make a video but i lost my transfer cord and i don't think the recorder would pick up the noise...

I start up the bike, say, to take it out for a quick spin, when I pull the brake lever the back brake light does not turn on. When I press the brake pedal, still no luck. The back light must be dead then, right? Can a simple bulb replacement be done, What will I need? The ironic part is that I have another rear fe...

Hi all, Thanks very much for the info on the flywheel puller. I finally got that off and went to replace the sprag clutch. Both idler gears and all bearings looked good.

I only recently brought my TTR on a private sale, good clean bike but, it would only run on choke but the engine sounded ok so I brought it. I found it was so clean due to over pressure washing water and some sort of cleaner had got into the carb via the air box. I stripped and cleaned out the carb, drained clea...
