Hi folks, not been on here for some time now, not been riding much after a bad injury. But anyway, I had stripped my 954 blade down and repaired all the cosmetic damage, put a lot of hours in, and got it all back together and looking fresh again. 600 miles later the engine started running rough and eventually was going off a cylinder on low rpm and idle, also a mate said it was puffing smoke odd times on deceleration. To cut a long story short, I have split the engine, and the cylinders are all scored on the front and back. I have not got many options now other than rebore/plate the cylinders. I bought the bike with 13,000 miles on it, now it is around 30,000, had oil and filter every 1000 miles since I bought it, so I was quite surprised how bad it was for the mileage. What my concern is, if I get the engine replated and new wiseco pistons in there, will this problem re-occur as it is clearly a bad design with the piston skirts being so short, so I can't see rebuilding it curing the problem of scoring. Has anyone here done the 980 and covered a lot of miles afterwards, did you have to split the engine again later, have any problems etc?? I am in two minds as to whether its even worth fixing given the scoring problem.
