Arigato:
If you go with the big bore, make sure you have the crank balanced and welded too. Othewrwise, you'll have a lot of vibration and a bunch of bottom end problems.  How do I know? Just ask my credit card!

BrianSM,

With stock squishclearance and compression ratio you get lower power
with higher fueloktan as 110 oktan. :wink:
(Slower flamefront in combustion and no real use of that higher oktan).
Put in a new headgasket approx...0,4mm and somewere around 100 oktan gasoline and ALWAYS measure squish clearance,not below 1,3mm or you got a "headbanger". :evil:

Brett:
Doordie, are both those headgaskets off a kx500? They are very alike but have small diferences, is there two different cylinders and heads available for kx500, if so what year did they change and pro/cons of each. cheers

BrianSM:
Thanks Doordie......so maybe If use less octane I should get another 5 HP !!!!!!! :) lol......hell at this rate I'll see 65 hp sooner than I think.....Thanks for your info I do appreciate it...I

doordie:
Brett,

right 1989 and further... :wink:

Brian,

Yes, you CAN get more hp with less oktan, IF it?s tuned for a specified oktan! :wink:
BUT best is ,high oktan and right compression and timing for that fuel. :twisted:
