Like I said, I don't want to get crazy because i really want reliability. I like to just maintain air filter and, oil changes (oil fiter too) and, gas and, ride.

How would say a Port Job, stage 2 cam and, the springs mentioned above, a 11:1 stock bore piston run for me? And, could I do this stuff myself? I'm mildly mechanical. That would probably be all i'm willing to chance! (can't see 26cc making that much difference to go 686)

 

I would do that and add the sixsixT adaptor..........

you will have a fast bike then!

 

What Octain gas do you run w/ 11:1 stock bore?

Can it put in the cam, valve springs, and, piston in then have someone port it for me? Who should I call to port the head?

O, and, what cam? I've seen Hot cam, Wem cam and, a few others.

 

Craycraft does a good port job and includes matching your intake boots and a 3 angle valve job along with installing the springs. I would also get it bored if you going to get a piston, the cyl. needs to be fitted to the piston anyways.
I like the hotcams.

 

Dude you just need to call Craycraft. There in the buisness to do what you want they way you want it. I've seen them boyz race around here( dallas ft. worth area) and they are it for the raptor.

I think this is the site. When ever I get rid of the polaris it'll be a craycraft reptor. But I have to try alky on my bike before then.
