ok im finally going to jet my raptor after forever. All it has is a fmf powercore 4 slip on and a pro design K&N kit. Where i live its about 80 degrees but getting colder
I own a raptor 350 with a pipe and air filter kit and i dont know if i should go down to a 12 tooth sproket or not. i just dont know if i want to loose that much speed. How much does a 12 tooth take away mph wise?
I have a Raptor 350 with a FMF Powercore 4 and Pro Design intake kit with a K&N Filter and i was wondering what size jet you think i should use? i dont know my elevation but i live in Madisonville, KY and it is around 70 degrees and warming up
