Are there any high compression piston kits to push the comp ratio to 11:1 to squeeze out some extra performance? I know you'll have to move to premium but I've been searching around and can't find many details.

I'm new to motors and what not. Can I take just about any old 52.4 mm piston with a dome and slap it in for increased compression?

I'm going to read about measurements and what not for doing this.

I realize I probably sound like a idiot but I bought the grom for the fun and learning about bikes in general.

^ yes and no, yes in that if the deck height an wrist pin size are the same it'll technically "fit" but no in the fact that the Grom uses a twisted valve style so unless you have new relies cut it's likely the valves will touch the piston
