I finally tore down the top end of my motor. I bought the bike with the engine stuck and never got it to completely spin free, so it is time to look at the carnage. Bad rust and some pitting. Bored to 2nd over, pistons, rings, gaskets or buy Mike's big finned cylinder/piston 650 kit? I like that everything is included, but is the quality any good? Does anyone have real experiance with this kit? I have read about all the hit and miss quality issues from Mike's, and I'm hoping for a little advice.
