So, I'm looking for more power! I have a '94 raid. I am hoping to add electric grips and an electric vest. Grips run at about 60 watts. That's almost half of what the stator produces. Are there any aftermarket stators for the bike? Am I looking at a rebuild?

Years ago when I last went riding I used to fill up my backpack with all types of useless crap that was heavy and probably only usefull on everyone elses bikes.

Hi guys, I bit the bullet and picked up a 2000 TTR-250. Was riding it fine up until yesterday. It started bogging when I tried to go full throttle. Then it stayed reving higher than normal at fully closed throttle. Done is done and she's mine now. Now it starts up but only stays running when I apply t...

Would simply replacing the standard piston with a wiseco high comp piston of the SAME SIZE offer any power or torque gain?

Hi Everyone, Tearing into my new to me TTR project - my first one - bought it not running. Is it possible to confirm the engine year from the serial number stamping? My bike is a 2003 (build date 06/2002, 10th digit '3') - looks like maybe the engine has been apart - the piston is missing and the connecting r...

Okay! My "new" 2011 TTR250 is arriving in a few days, and I'm sorting out what tools I need for the workshop. What would you guys suggest? It's been a long time since I've owned a bike, and suggested tools for the 250 would be appreciated. Also, what gap have you got set on your TTR250? Cheers

Riddle me this! I am just stripping apart an engine that I bought as part of a job lot many years ago and I have no idea as to its background. It's from a metal-tanked bike as it has the extension on the transmission shaft for a magnet plus its number is 4GY whereas the blue TTRs invariably have a 4PX engine n...
