I have a raptor with a sparks exhaust on it and a uni air filter I want to get some new sprockets. I want to be able to go up hills like olds pretty fast but I dont want to lose top end and I dont really know a lot about sprockets so any suggestions wuould be helpfull. thanks

 

Try dropping the countershaft (front) sprocket down to 12 teeth and see how you like that.

 

if I do that I wont have to change anything on the back sprocket?

 

Hey man I had or am having the same problem. I seem to be getting smoked on Olds hill by other Rappy's.Especially off the line.... I have a K&N filter White Bros.R4 exhaust and a jet kit and just now finished putting on a 12 tooth primary and noticed a good bottom end increase.(of course thats up and down my street) Going from 13 to 12 gains you approx 8% more bottom end but 8% less top end.... My problem was that I couldn't get out of second gear on Oldsmobile.... Other guys were in third gear by the end of the woops. Hopefully this will help ya decide. Good luck [img]i/expressions/face-icon-small-smile.gif[/img]

 

Oh ya.... .... I took out two links from the chain after installing the 12 tooth sprocket... I did nothing to the rear sprocket......(yet).[img]i/expressions/face-icon-small-happy.gif[/img]

 

the trick to Glamis is run the 12 with that set up you guys have and click into third before the whoops and pin it right after all the way up..

 

thanks for all the advice im gonna try putting a 12 tooth in
