so if I do just the piston is it going to be worth it do you think?

If I was you I wud spend a few more pennies and get the cams it would be worth it and ya mase well while the top ends off mate

Yeah true, I'm tryin to keep cost down right now cause the tranny is getting rebuilt too. Thought if I put the piston in now then when I get some more scratch together then throw cams in?

Yeah mate ya could lyk especially if you have spent a bomb on ya tranny issue mate just make sure ya torq the head properly becouse it leads to head gasket problems

Yeah thanks dude, good luck with that hill too! just checked out those pics. Bike is sweet!

Ne prob mate n yeah hard work lol kxf's best bikes ever built ;)

both motors run the same compression so the pistons should not make any difference unless the barrel's or heads are different on the 2 models.

Both bikes don't run the same compression at all thats why 12 are known for head gasket blows or leakages (mostly if not torqued right) and also states in the manuals different compressions for stock

In the United States, they both show 12.5:1. Yours may be different though.

That's what I saw also, it hasn't changed from 12.5 since 2008 or so

So it won't really do much good without the cam swap anyways? But won't harm anything either?
