So, last night my TTR was stolen/joy-ridden. After it not being where I left it, I searched a couple streets and found it parked in one only a couple hundred metres away. They'd broken the steering lock, and then opened up the ignition housing on the other side of the key insert and cut the ignition wires...

I Cleaned my carb (it was really dirty the diaphragm had nearly disintegrated) the previous owner had also stripped most of the screws, ez outs saved the day multiple times. when i put it back on the bike it started easier than ever before and it idled (it used to just die) then i gave a little twist to the t...

Do you guys check it when the engine is dead cold (been sitting overnight) or do you warm the engine up for a minute or so then let it sit for 5-10 then check it? I swear I read somewhere you check the TTR cold but everyone I know with a more modern bike checks it with the other method

Hi guys, Just to be clear: all questions I'm asking not usually are just from one motorbike. As I'm helping my friend at his garage, first TTr was the one I wanted to keep; second belonged to a customer, than then brought a third one, so yes, they are three TTR's I've been/I'm asking about. While checking...

However I have little to no compression stroke when turning the engine over from the crank with the socket I have no resist...

Hi there everyone ! my rear suspension is way to hard even after adjusting the dampening to soft and the adjuster on the bottom of the shocker. I would like to back off the spring tension by undoing the two adjusting nuts ( I have the tool for this ) but getting to it looks a tad difficult, can you simply remo...

The guy who owned this ttr 250 before me apparently did not know that the float pin only comes out one way and broke both of the float shafts right at the hole. He put JB Weld on it but as soon as I put gas in the bike they softened up and fell off. What's a good alternative for repair? I tried to solder them And...

Has anybody upgraded the springs in the standard 43mm forks, I tried to get some progressive springs from Hagon shocks but they don't make any. I was just wondering if anybody had done anything similar? Cheers Andy

Couldn't find anything on my problem, I'm sure it's an easy fix but it would be a bit easier if I new where to start.

I have a problem with a TTR 250. Engine jumps well with choke and runs idle without choke very well. When driving comes no power and the engine jerks. Feels too little gasoline, or misfiring. Who can help me with tips? I would like to sell the TTR, but only if it drives well. Many Thanks ! Chris

I need to replace the gasket on the right-hand side of the engine case because it leaks oil. Do I need anything to stick the gasket down or do I just throw it on and put the case on?
