Need advice

[yuana]

He guys, ;D

let's say you have a hmf pipe and a pro-design K&N filter on a raptor 350 with a 14T sprocket, is it possible to install a aftermarket cam or do you have to do more engine mods first to change the cam. I haven't got a clue! :-/
I see so many options these days for performance gains but I don't know what really works.

Thanks in advance

you can get a cam... id sugest like a powroll .390 lift cam ive always heard good stuff about powroll. If u do motor work then get a higher lift cam like a .430

higher lift cam like the .430 lift requires stiffer valve springs as well

But is the powergain real noticable like when you replace the cam in a YFZ450? I know the 350 Rappy is not a YFZ 450 but just looking at the dramastic change of power.
I've seen video clips of YFZ450 that changed the cam and raced against a standard 450 and the one with the cam blew the standard away. So could you really blow the standard 350 Rappy away with the .390 cam.

idk really . but im pretty sure on the bigger machines you get more hp outa aftermarket parts then you would with the same part on a 350 (correct me if im wrong)

Ok, still willing to try the cam but think I will start with the .390 because I don't know how extensive the motor work will be.

.390 sounds like a good cam. i was considering getting that cam myself, unless of course i decide to stroke it, then i'll just get the .430, but i'm not sure what i want to do yet!
