[QUOTE="idl1975, post: 1376335, member: 95230"] Thanks guys. Good points, and especially that no compression could be the problem. I can't believe it's a fuel or spark problem as I've seen a strong spark and an extremely clean carb. It was the previous owner who did the rebuild. I take the point that he may well have been dodging a bullet by selling it, but OTOH since he did rebuild it himself, I would have thought if there was a compression problem he'd just tear it down and fix it, since he'd put a lot of work into the bike. I'll look into checking compression. I have the original reed block, so could swap that back in. What should I be looking for when I inspect the carbon reeds? I'm not a two-stroke expert by any means (have a TY250 twinshock, but it's pretty bulletproof so this sort of thing hasn't come up :) ) Just managed to break my collar bone, so I'll have time to strip it down if necessary... :ahhh: Tom, thanks for the SR info, it's tough to find. I'm going to assume the KIPS isn't an issue. What carb is yours using? Mine's a euro model and I _think_ the US bikes used the KDX big-ass carb, while the euro bikes got a tiny 32 or 33mm PWK. I'll get a 45 to try as well. [/QUOTE]
