what kind of mods can i do with keeping the stock bore in my cylinder? I'm not ready to bore my cylinder yet but i want mods that will give me some extra horsepower... Eventually i want to have my stock 400EX motor push an extra 10-15 horsepower, but im sure ill have to bore it. What are all the things I can do to achieve this desired modification?

Put a high compression piston and a cam into it with a good exhaust system.

I still have the stock bore, and I am pretty sure with all my mods I got an extra 7 or 8 horses. It feels like it anyway. I can spank stock raptors and banshees. (yes, I said banshees.) My cousin has a raptor and he just bought a Curtis Sparks X-6 pipe. He was excited and expecting to beat me, I was expecting it also. We raced 3 times and it was dead even each time. I mean we are side by side. When I get wide open he barely pulls by me. (just barely)
