The cam souldn't hurt reliability any.

 

I hvae an xr650 cam in my ex, and it works great, no bogging at all

 

I also was wondering if I should order a jet kit? Currently I have a White brothers R4 full exhaust. A K&N air filter. I just moved the clips in the Carbs. Runs good now but with the cam Should I Change the main?

Fast440,

Which 650 cam are you using? XR650L or R?

Choky,

I would only use the Stage 1 in a stock engine. It produces more torque and HP all through the rpm range once a pipe and ket kit are installed.

how much does a stage one hot cam set up cost??? lets say i have a stock raptor with a k&n filter, what would i be into with a stage one???? i know i would be getting a a pipe so dont add that in the price. how much horsepower do u add???

 

Big,

MSRP is $149.95 for the camshaft. Nothing else is needed for the install other than some Yamabond 4. You're looking at about a 10% increase at peak for the Stage 1. It develops more HP and torque everywhere in the rpm range with a well set-up machine.

will they give you better OVERALL power or just top end?

 

The Stage 1 will. The Stage 2 is good for mid and up on a stock bore, stock compression engine. With a 416 engine, it becomes very good everywhere.

Hot cams- I went back to the stage 2 after a 2 week try of the web 685. Still smiling. I was on Bob's sons raptor saturday with 35mm FCR's into a custom intake. The right intake makes a world of difference. After i got off the raptor Bob's son came over and checked the avenger 2 EGT. Said i was shifting at 8800 rpms. I was still making good power on top. Very impressed. I felt (butt dyno) the stage 2 was making power up there. I thought the stage 2's peaked at 8200 rpm?

 

Excellent! Glad to hear (read?) it.

Thanks.

Tony
