best bet seems the replacemet carb.(i'm watching Stoo to see how this goes)
From what I have been told, and based on my own experience I suspect that a lot of tuning work etc concentrates a little too much on free-up the intake of the XR in order to maximise the tope end power output. It wouldn't surprise me if this in turn tends to screw up the initial delivery.My bike benefitted from a long setup period, with perhaps a total of 30 or so dyno runs and loads of test rides covering various carb/exhaust/jetting options. The end result uses a pilot jet considerably smaller than most people end up recommending, and the retention of the backfire screen. Despite this my bike still puts out a respectable 50bhp at the rear wheel - which seems to be about the limit for most XR6's.
Interesting. A kick in the seat is OK for wheelies, but not when you're cranked over in the wet or backing it in IMHO.

WHat about fork seals? More than one person has mentioned to me about how XR6s blow fork seals. A few I've seen for sale, like the one on ebay is sporting "new fork seals". Is this quite a problem then? Is there no mod for this?
I'm GUESSING here, but i think blown seals are more likely to be associated with over-pressurised forks.having said that, any xr600 pilots can tell me what pressures theyve put in their front forks?(I havent messed with mine yet)
I'm all ears
