GottaGo- do you have any PICS or tips for how you did your porting? How do you know your doing it optimally?

is there any guide to porting the raptor head? Or, pics out there of before and, after?

I will have pics here soon of everything. Any tips, yeah I have one really good one. I am a diesel mechanic with quite a bit of mechanical experience and here it goes, DONT DO IT YOURSELF!!!!!!! I found this out after taking it to have the seats ground. It has now cost me $300 for him to fix what I screwed up. It is a science and that is all that there is to it. $300 and maybe 6 hrs of my time, not worth. I have also heard of people being able to modify the stock carbs to perform alot better, but the mods are permanent though, have you guys heard of anything??? In reply to the other guy who has a LE, why keep it stock??? Gotta have fun going faster than the rest of them. Why do you need a new timing chain? Mine only has 20 hrs on it, it shouldnt have stretched, right? Thanks for all the info guys

Isn't that the truth. Mine is 6 months old, and has around 35-40hrs on it, and it's already in a million pieces with most of the motor at Craycraft.

Just not worth spending the time and screwing it up. What do you retorque the head to after a couple of rides? What about the timing chain???? Does it need replaced with so few hours or is it just a convenience thing??
