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. What basic tools and spares specifically suited to a TTR should I carry as a minimum? Generally we wouldn't venture anymore than about 100km...

Hey guys, Mat here I have two broken mountings on my airbox, caused by a perished bump stop on the rear shock allowing the tire to grab the mudflap and rip the airbox downwards after what I presume was a totally sick jump (Thankyou previous owner). This is the top mounting. My plan was to heat the plastic a...

Hi again, I heard my girlfriend's 325 started to sound strange and has been off the road since.

So I’ve got a ttr 250 1993 with electrical start no kick.

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?

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.

Hi all, hope you all had a good Christmas. When my bike is idling my bikes at a nice 13.5 volts. (Fully charged battery on the bike), when I ride it the voltage drops to 6-9v but then goes back up to 13.5 volts when on a lower but steady throttle. I'll pull the generator off and try to check it out, has anyone...

My battery keeps draining a bit when I am not using the bike for long periods of time 😑 so today I fitted a new regulator, hopefully it will fix the problem

Hi Folks, would appreciate a bit of advice on this if possible. The riding experience on my 05 TTR is best described as "clunky" with respect to the throttle take up, smooth and progressive it is not. Don't think it has ever been really smooth since I've owned it, but I would expect everyone here who ride...

I was cleaning up a clutch cover from a blue TTR and thought I would check the crankshaft end oil seal.
