banshee_terror_ Posted February 8, 2009 Report Posted February 8, 2009 i was dradding a few guys today on a frozen lake and i raced a raptor 700r and the problem that happined is i was creeming him i was in fourth gear and switched to fith and all of a sudden it lost power lik it slowed down. so i shifted back into fourth and lost by 1 quad lenght and the race was easly a quarter mile if not longer. but i was like fuck it and keep riding the whole day and i raced a piped and cammed trx 400 or 450 and it did the same thing in the race and got murderd by like 4 lengths. wtf. i have no power 5 and 6th. i dont know if its a gas problem maybee a new petcock or port the fucker out im so pised.... also i was letting it sit for a bit cause it was getting hot and i threw snow all over the motor. and then i took off to go race the same trx cause maybe it was a fluke but i got murdered anyways it sounded like i had a rev limiter in it. wtf happined there. dont meen to have a long post sorry for that i just have to explain my storie.

locogato11283 Posted February 8, 2009 Report Posted February 8, 2009 if youre drag racing 1/4 mile its very possible youre running the bowls dry. if you think its the petcock, take it off and inspect it. it might have shit built up around the screens and fuel might not be flowing through it properly.

locogato11283 Posted February 8, 2009 Report Posted February 8, 2009 what is it that you want to know? changing your jets wont solve a possible petcock issue. also, if youre running the bowls dry, changing jets wont solve that either. if youre doing mile and a half long races, i will almost guarantee that youre running the bowls dry.. no gas = no power and possibly locking your engine up.
