[QUOTE="Nighthawk016, post: 174732, member: 334"] CDI's are not known for dying on these years of 125's, check your grounds, spark plug wire and boot. 87 and 88 jugs, heads, and crankcase will work, however the internals are all completely different, IE piston, crank, con rod etc etc... they shared the same powervalve setup, but the power valves are NOT compatible. The bores came factory as non coated iron bores, if you are over .040" or 1mm over i recommend resleeving the cylinder. The powervavles are known to fail on these bikes and fall into the cylinder. I run mine with out the power valves and it runs fine. If you need anymore info let me know! [/QUOTE]
