Which 96mm cylinder's are you talking about? The cylinders that came with the pistons?
I had stock 94mm cylinders bored out by Rimco to match the 96mm KB pistons. The old set of cylinders that came with the KB's didn't fare so well after 10k miles, hence the rebuild. |

is your avtar the melted piston your refering to? did it happen with the aftermarket cylinders or with bored out94's. this is my biggest concern. are there good AND bad aftermarket 96's? the avatar piston happened on the first drive of a new rebuild 5yrs ago. throttle pedal got stuck, my dad's first reaction was to give it a quick jolt with his foot but that made it stuck at WOT and snap, crackle, pop the fresh engine was toast. That was not a happy day. Both he and I have kicked ourselves for not just turning the key off rather than listening to it roar at WOT... Ahh, memories... fwiw, the cylinder used during that session are the one's that came with the KB p/c sets. Not sure if the same cylinders come with the sets these days. I rebuild it last summer b/c I had it mistuned and overheated the engine (damn operator errors (IMG:style_emoticons/default/headbang.gif) ; oh yeah, that operator is me). Anyway, the cylinder's expanded due to the overheating and are out of tolerance which is why I've gone to the stock 94mm's bored out. I think cost wise, it's a bit more $ going the 94mm bored route but if you can get a set of stock 94mm's in the classifieds for $50 or so then Rimco will match them to your 94mm pistons for about $150 (then there's shipping). Not terribly expensive but budgets vary. -pt |
