The first dirt drag of the spring is this Saturday, and I've never actually raced in an organized fashion. I've got the stock tires I can run, or some brand new 18 holeshot mx4's. I was thinking of the 18's with 15 front. Anything besides the lowering blocks I can do in a weeks time to clean house at this thing? Thanks.

 

I would not put the 15t sprocket on to drag race. I would put the 18's on to gear it down some. A good cdi box would help you out.

 

dealer called hpd friday, and the new cdi is supposed to be delivered this week. its been on order since i got my pipe. anything else? how much difference does plastic make? as in cut front.

 

I don't think it would make that much difference, I think it's more for looks then anything. What cdi box you getting.....is it made by hpd?

 

yea, its from hpd, i think its vortex? where do the cfm blocks come from? they weren't on their site.

 

I got them off e-bay. Here is the link.

 

Who sells a 15 tooth front sproket??

 

ernie660r what all is done to your raptor and where did you get the parts to do it

 

sprocket specialists sell 15t. sometimes ya gotta knock part of the ears off the clip to install, but it fits the shaft fine.
