Question about 2003 Yamaha TT-R 125 E

1 Answer

I am a mechanic and own sevral bikes pw 50, cr 125R, xr100R,etc

I am a mechanic and own sevral bikes pw 50, cr 125R, xr100R,xr650R,rm250, a pro pitbike...and so on and on my pw 50 i had a simalr problem... i tore the bike down and built it up use then did it again but this time a found a major problem... there are two silinoids in most bikes one is a running coil the other is a starting coil.... if your starting coil is good the bike will run for about 0-8 seconds then die this is due to the engine once it gets itself warmed up enough it will automaticaly switch coils and if you running coil is bad it wont run.. i sugest finding your running coil and bringing it down to your local dirtbike or auto shop and having them test it.. if u need one they can be cheap ($30) and get expencive ($800) urs will prolly be cheaper due to the popularity of that bike. hope that helps

My dirt bike fires up and only runs for like 20 seconds what is wrong with it

There could be a few things to look for when this happens. I found on my KLR 650 i had a bit of rust or dirt in the tank that had clogged my fuel line by the shut off. If the bike has been sitting, the fuel may have gone bad or started to "gel" in the bottom of your carb bowl causing the float to hang up or flood the bike out. Hope this helps.

Bike stall

what should I do?Check the fuel tank petcock position. Check that the valve is in the proper position for fuel to flow. It happens. It's possible that the spark plug is fouled. Remove the plug and inspect for evidence of fouling. Clean and replace and then try starting the engine.,
