Hey all - looking for XR600 experience. I am getting a '97 XR600 with quite a few hours on it and it will need freshening up. While I have it down, I am considering a 660 piston, 9:1 low compression so it will run fine on pump gas. Also maybe have the head roto-rooted some. Plan to run a fairly quiet exhaust and DS the thing. I just want to get it to run 100 MPH at altitude around 8k feet. The bike has been GPSed at 93 MPH WFO at 2.5k feet in current form. My friend that had the bike has owned several 600s and that this one was one of the slower ones he's had.
So, about the 660 kit. Does it add much vibration to the bike, seeing that I'll be DSing it? Do I really need to go to the lower compression piston, or can I use the normal big bore kit 10.2:1 piston and be OK with pump premium then dump some octane booster in it when I have to use low test or Pee-Mix gas in it in Mexico? Specific to fuel questions, understand this bike will be in the Rockies most of the time and I want to be able to burn pump premium up here which is like 91 octane.
Thanks for your comments! Leo.
