ok i just changed my head gasket. I thought that was the problem with my 250r. I'm kicking it and I have spark it wont start it blows a puff or two out the back at the bottom of every kick and feels like the plug isnt firing at the right time i have no idea whats wrong and it gets fuel? is it a timing problem lol or is that a dumb question???

did u do a compression test or a leak down test....will it start if u try pull starting it? if so, it could be low compression.

take off the flywheel and make sure your timing marks are on...check the manual for the right timing. i know there is a mark on the case that lines up with the stator.

it's getting fuel? do u have strong spark? check out your coil, cdi, and stator with an ohm meter if u can.

electronics going bad, out of time stator, low compression are all culprits.

try a new plug also. and after u checked the timing, try pull starting it.

i had the same prob with mine and the key for the flywheel was broke and the flywheel had moved put a new one in it and it started right yup

Ok this happened to me and I took it to a local shop because I couldn't find the problem. They said the ignition coil was shot. It cost $110 installed. It was odd when it happened too because one minute I was riding then I shut it off so I thought I fouled a plug, I changed it out and it still wouldn't start.
