maybe ill buy this set and use the M-Speed cylinder and crankshaft
They LOOK fast, but i'm not sure if they are....
All the hype seems to be just advertising....I personally have found nothing on them, no reviews or anything, i think KHB have sold very few of these. I'd also worry that the KHB graphite piston might throw the engine off balance.
Having said that, i have no right to give my opinion on a product i know nothing about, so go and buy one, then tell us how it is. As for durability, who knows, i'm sure KHB would be quick to tell you it will last 1000 gallons...
