My 01 starts funny on a couple spins then cranks over...an then sometimes it fades an backfires. After a ride an while it's hot it's really bad an back fires a lot then finally starts...I smell fuel sometimes an choking it makes it worse an will throw a fi code then goes off, I've tried to catch the code but when I try I won't come on... it's also burning the spark plugs, the only change I've made was coils an air filter but the problem started before I did those things... about to change the strainer an floater filter but after that I'm clueless.... I need help please!!!!
