increasing the bore a few sizes will give you no HP increase, other than the fact the bore is round and sealing better, if you melted the top thats not oil but a lack of fuel can you post a pic of the piston?

 

[blasterfreek30]

right on gonzo, the fuel is what keeps ur engine running cool

probably jetted to lean or air leak.

sounds like you run it to lean,it would be a good idea to have the bore checked,youll probibly need to rebore the cylinder if youve cooked the piston

if u havnt removed ur oil injectuion remove it first then premix. if ur cylinder is skoarded and u need a rebore go up the next size and get a new piston. boring out that small does nothing for horsepower but merly gives u a clean fresh cylinder.

The aftermarket pistons will give you a little more power too. Boring it out is just to get nice fresh, clean cylinder walls. Be careful though, you have to break in aftermarket pistons carefully, and they need to be warmed up with much more care than a forged stock piston.
