Hey guys I have recently picked up a ttr250 on the cheap and I'm working through its little problems. Biggest one is that it won't start off the motor (grinding). Pretty sure I need a new sprag clutch and I figured a new starter gear as well but looking through the case both the teeth on the motor and the lar...

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

Blue model 35,000km with little dirt work but i do get up it through the gears on the road at times. oil changed every 1,500-2,000 kms , although i dont know the first 10,000 km history of the bike.

Looks like I need a sprag clutch, idle gear and started motor :( Any one got any of these parts and willing to sell, I have read it is best to buy a brand new sprag clutch.

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?

Hi all, I have pulled the carb out recently on a 2007 TTR250. I have seen a couple of pictures where people have said there is 2 O'Rings under the cover of where the diaphragm and needle are. Is this true for my model? As when I pulled it apart, none fell out. Perhaps they have perished completely? Tim

Does anyone know if applying plasti dip to a cracked carb diaphragm will work to seal pressure? I will eventually replace, but I just spent $75 on carb rebuild parts and don't want to spend another $35 just yet. I assume it would be best to apply to underside of diaphragm due to the suction. Does gas c...
