Okay so I'm planning on doing some engine work on my rmz 450, I need advice.
I'm gonna use this bike for supermoto races and maybe an occasional trail ride here and there but mainly supermoto. I'm looking to increase power with as little to no loss of reliability as possible. Reliability is, overall, my main concern.

I plan on keeping the stock head. I'm looking to find the best combination of maybe increasing the bore and/or raising compression. Does anybody know of any pros & cons to different combinations of having

stock bore with stock compression
large bore with stock compression
stock bore with high compression and so on

I'll be using wiseco parts.

any advice is much much much appreciated <3
