I have been noticing that there are many different cylinder configs when pertaing to this particular motorcycle. My buddy just unloaded a real gem on me. The cylider that appears to have come with the engine is plated (destroyed). Ad the replacement jug has a steel liner with a stock piston in it. Both jugs are 85-87 types with the round hole powervalves. Can anyone shed some light on this for me? The piston appearsto be cast. Was my bike manufactured in a transition period when Kawi was trying to tone down the bite of it's big bike? The manual I have shows that the carb size went down and thcompression was lowered for that paticular model year. ('87)
Thanks, Bob Shy

Whoa, One question at a time, and more paragraphs.
Cylinder from at least '86 on has a plating--not a liner--when stock.
How exactly is the cylinder destroyed? Severely gouged, or just worn down?

It as quite bad siezure marks on the intake port and the exhaust port as well as a 1mm gouge in the intake port. I realize that plating and a rebore can repair this (along with a larger piston :evil:) but I was wondering if the steel linered cylinder included with the bike would be cool to use?
I haven't checked the clearence of the cast pistoned steel lined cylinder yet, but the book says service limit of about .003". My calibrated :lol: hand says that it feels looser that that.........sooooI'm guessing at best I'll be needing a new piston.
There hows that for paragraphs? :-D
