Hi All, I'm new here and have a question. Anyone have any experiences with large bore kits for the 650 L? I'm looking at one done by an outfit called Kustom Kraft that has a sleeve and slug displacing 720 cc. It requires boring the cases and before going thru all the expense and hassle of doing this I'd like some input either pro or con!? Overheating? Exsessive ring or piston skirt wear? The guy I bought the bike from neglected to inform me that the jug had already been bored to 101mm and it shows some taper. It's either go bigger or find a stock jug and start over. I see Wiesco offers a 102.4 but I'm afraid the stock jug just won't have enough metal left to cool properly or resist hotspots and/or warping?! What do Ya'all think? Any help?
