KFX450 WONT START AT ALL????

[scotty_33]

Hello, I just purchased a used 08 KFX, which had a slip on HMF and airbox lid removed. Since i bought it I also bought a full procircuit exhaust which i just installed and now am waitingfor my cfm intake and powercomander to come in. Last night i had the bike running with no prblems. I try to start it today and it turns over and everything, fuel pump primes and everythin, clutch pulled in, in neutral everything and the bike wont start. Even tryed bump starting it with my truck down the road and nothing at all??? I did leave the choke on all night(forgot to turn it off) but the key wasn't on and the kill switch was in the no run position aswell. I haven't touched anything on the bike except the exhaust since i bought it 3 days ago???? and it ran fine befor i puled it in the garage to put the exhaust on. Please help i still haven't even took the quad out for a ride yet and am dieing to try it out!!!!

First check your roll over sensor, it's under the hood (you can do a search here and you'll find a pic), you may also need to adjust your TPS as well which is pretty common, if the voltage is off dramatically it may not start at all.. both of these are real minor issues.
