i just got a raptor this weekend, and there seems to be something wrong w/ the reverse. if i get on a hill it wants to start bogging, no matter what. even if i push the throttle all the way in, it'll die. the previous owner put a white bros r-4 slip one pipe and white foam filter on it. it hasn't been jetted, is that the reason it won't pull in reverse? help me please[img]i/expressions/face-icon-small-smile.gif[/img]

 

I have had the same problem. I believe it has a rev limiter on reverse, like the parking brake.

 

maybe, i'm going to jet it and see if that helps. how do you engage the parking brake? know that's a stupid question, but mine still rolls when i do it the way the manual says. and my brakes are still very good.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Try adjusting the park brake, and it probably dies cause the rev limiter

 

You can adjust the parking brake on the clutch lever (top one).

 

ok, and how do i adjust the rev limiter?

 

There is a rev limiter for reverse. You can bypass it but you rev light won't come on or you can buy a bypass kit that will allow your light to come on but not the limiter.
You still may want to rejet it anyway but that's not your problem.
You need to adjust your parking brake.

 

yea, thx.... i still need to rejet it though, just to get the full potential outa that pipe

 

i have the wb r-4 pipe and white air filter, does anybody know what jets to get, or where to look to find out? thx
