2005 KX250F Fresh rebuild, having problems
Hey guys, i picked this bike up a few months ago from an add or craigslist. The bike was for sale as a project, previous owner tracked it pretty hard. Crank bearing let go. So i got the bike pretty cheap
I took the motor apart replaced the crank with a Wiseco forged crank and all wiseco gaskets and seals. stripped both case halves completely down, washed, and rebuilt with new bearings.
I placed the motor in today, bolted everything back up. Its not running though. When i got the bike it was already taken apart, so i there's a chance i could have missed something when i put it together.
so it turns over, sputters sometimes but wont run. Ive witnessed a few backfires out of the exhaust as well. What do you think is wrong? I remembered to set my timing correctly and checked it a few times. Weak coil? carb issues? im not 100% sure how to set it correctly.
Any and all advice you can give me will be greatly appreciated!
