My setup is a 2001 raptor, durablue axle, front wheel spacers, Curtis Sparks Racing System, K&N proflow kit, air box lid removed, I am having problem jetting this bad boy, I have 160, 165, 170, 175, mains that I can use, I also have 27.5 pilots to put in but have no idea on any of the carbs settings and which mains to use I live in North Missouri, but I also ride in oklahoma, I am also moving to Pheonix later this year right know I am worried about Missouri, I am also wondering about the gearing that would be good I drag race a little but mainly like to just haul *** around

 

I would suggest purchasing a jet kit! But before you do that hit the search button and type in raptor jetting....that should keep you busy for the rest of this month.
By the way...which part of Phoenix are you moving to?

I am moving to the northern part to go to MMI in July, I would really like to try and jet it without the kit since I already have most of the jets and I'm a little short on funds right now

 

Hey, I run sparks stuff on two raptors. I couldnt get them to run right until I got dynojet kit. I'm surprised they didnt tell you when you bought the parts from sparks. they were very helpful. So what sparks parts are tou running?

 

My guess would be:
165/170 maybe 170/175 if that exh. has no spark arrester.
4th groove from top on the clips
2 1/2 left 2 3/4 right mix. screws
Good Luck!

 

At the time I'm not running any other sparks parts but the exhaust is an x-6, I'm planning on doing other work later but right now we are in the middle of moving thanks everyone.....shmave
