Hey, It's been a long time since I posted here. I'm looking to Dyno a stock XR650 and chart the changes of different parts. Specifically I'm looking for bikes that have had head porting work done. So if anyone is planning on porting their head and installing a cam, from a stock engine to hopped up.. I'd like to dyno it and get snap shots of the differences as parts are installed. I have an XR600R 100mm bore, that has the head done by XR's only with big fins and all.. and it's faster than all get out.. but I bought it like this so I didn't get to see the difference's as it was built up. I'm in the bay area and have a dyno at my house.
