IM trying to fix a Yamaha big wheel 350 4stroke, the bike is very hard starting, once u get it running it misses and backfires, spits and sputters, and is hard to keep it running. But if u can keep it running for 10 mins or so, after bike gets warm the problem goes away completely, runs like a dream... So what do u think it could be? Thanks
