[QUOTE="GMRaceworx, post: 1356340, member: 107831"] Okay I have a few questions on the 1990 kx250 engine I am hoping someone can advise on. The engine I have is going to get a complete overhaul and in the process tuned specifically for woods use. I want to bore up this engine as big as possible/practical also. First big question is that I would like to replace the tired old crank and rod with a hotrods crank. I see they advertise the 92' onwards cranks with 2mm longer stroke than the 90 model engine which would suit what I am doing, as long as the crank can be made to work without major headaches. Second the cylinder I have has been resleeved. The cylinder was bored under 74mm to fit the sleeve, so I am wondering if this year cylinder can be bored and plated to 74mm and made to work with the power valves used in this year? Any advise most welcome. [/QUOTE]
