Big Bore kits for kxf/rmz's

Recommended Posts

Starting to wonder about fitting a bigbore kit to my little thumper, has anyone here fitted one, and what sort of changes did they find.

Think here are a couple of the cheaper ways to go are:

Forward Motion 262cc ($375.00) and can have head totally done at same time for about $800.00 (head and 262cc) w/ KB SS valves and hardened lifters.

Muzzy 280 cc is about $450.00 after cyclinder exchange

Parts Unlimited (Athena) 290cc (special built cylinder w/larger cooling jackets) $650.00

No personal experience with reliabilty with any of them.

I have a 262 kit in mine, you notice the displacement pretty easily, as far as reliability go, I havn.t had any issues, would do it again in a heartbeat, there is no real magic to getting it done, milleneum tech did my cyl, stock head gaskets and base gaskets work just fine, wiseco or pro x both provide a stock compression piston for them, you will need to go up at least one size on the pilot, good gain for the money.
