I am thinking of big boring my king quad.
I found a place that does King quad work.
http://www.mt-llc.com/index.html
There kit comes with a CP piston, Boring, the recoating of the cyclinder, gaskets. All the crap to rebore it to a 750cc monster. Only problem...example pic... "The 6mm oversize piston is .236" or .118" per side. That seems like a lot of meat to be removed from the cylinder wall. I can see where the spacer would help the head gasket seal but what about the rest of the bore. Being the wall was thinner, could it potentially warp after the boring if your engine got hot? It doesn't appear as though there is much wall thickness to begin with."
they also had a problem with the head gaskets leaking, they come with a spacer, that gives the king quad heads gasket more surface area but "slightly" restricts the flow of coolant.
My king quad is a IE open deck cyclinder. Wonder how these type hold up to big bores.
I am new to this 4 stroke bore thing. I have only done 2 strokes before but the price for all this crap is $575. Is that a good price for jsut a bore, replate and pistons and gaskets?
On top of this I would be getting cam, cam chain, valves ect.
thanks, hope I made since
