Well merry x-mas everyone. I have a 660 raptor 05, that has been rejetted, k&n intake, yoshimura exhaust and pipes. For x-mas i just got a CDI rev limiter and a new High Peformance racing clutch that i still need to install. Now i am wondering what would the next best thing to do?

 

new piston,cam and port and polish.

 

Im with 89 warrior i like the cam ideal doesnt cost too much and with the 660 you would get a huge gain in power but the porting and polishing im sure will cost a pretty penny but would give you massive gains in power if you have the money go for it if not get you a cam.

 

depends on how much you want to spend and if you want to do it your self. Probably the cheapest thing would be a cam. Not too hard to install either. But if you get a stage 2 cam make sure you get a set of kibblewhite valve springs, or you will probably bend your valves. Then if you are are going to have head work done you might as well just bore it out while you are at it and upgrade the stock rod.
