Alright... I got a bunch of work done to my Raptor and it's makin' me very angry and b4 I take it to get looked at I hope someone and a good idea what it is............alright fisrt of all I would ride and jump alot well my negative on my battery comes loose and my quad would die...Then after awhile I would ride and when it was warm sometimes it just wants to die like it was getting too much fuel and not enough air and would sometimes backfire and shoot out a blue flame!
I did have my stock carb jetted and stuff but it makes me wonder if that's it...?
One of my buddy's said it could be my fuel mixture but I only run 40% 103 VP and 60% regular gas....... I got to go to bed right now for work but I will be on 2morrow to fill u guys in with some more info........please help me out...I wanna RIDE!

 

You could be running way too rich. A warm engine needs less fuel than a cold one, so a too rich engine will run better when it first starts up. And warmer outdoor temps will make it run richer and as it gets colder outside will lean it out some.

 

Okay thanks for the info dude...I'll see what I can do and if I have anymore problems I'll let you guys know...BUT is there a different kinda battery I can get or a different setup so my negative and stuff doesn't wiggle loose after jumping some 8 to 12 footer jumps??? I have a tie metal bar thing to hold it down but hittin them jumps it still moves some...

 

mine did the same thing. it was the carburetor syncronization screw. but i mean did it do this right after u got it jetted or did it come at a later time?
