well i have a banshee bored to a 370 with wisecos, milled stock head, port and polished, v force 3's, 34 mm pj's, +4 timing advance, pro design intake manifold, um billet airbox, 1/4 reed spaceers, lightened flywheel, running half 91 half 110, with elka suspension to match, ohh and i run pro circuit platinums with 304 silencers. up until now i just had a stock shee with the same pro circuits, jetted with a k&n and that thing was fast. i am waiting on the right size carb boots to get here in the mail and she will be ready to run. i am just wondering what to expect. i mean i know its gonna be fast but ive never ridden a quad with anything more than pipes and jets. anybody with comparable mods to give and opinion and also when i go to pismo in two weeks am i gonna be smoking people or what. im just getting anxious cause i cant ride it yet so i just ask about it on here. thankx

yeah for sure ....yeah 20 over means ...something like .020 inches i believe is taken off the the cylinder wall...maybe an engine builder could chime in to clear this up for a few...

Not sure what there is to clear up. If you click on the link I provided above, it will tell you the english (.020, .030, etc.) and metric (64mm, 64.5mm, etc.) overbore kits sold...which also tells you the displacement, taking into consideration it's a stock stroke crank.

 

IF the guy said boring it over .020 would make it a 370cc...I'd be weary of giving him any more business.

 

It's also good practice to buy the pistons and bring them to the borer/machine shop so they can bore to size...
