i know there 200s but thats rounded up... true cc's of blaster are 195 warriors are like 348s i think, yea its .020 over but its a different measurement its not 20ccs over, i think .020 is 1/2 MM because .040 over is 1MM, my warriors piston is i think an 84mm and 83 is stock.

Or something like that..... Yeah,.... I'm guessing something in that range too.... might actually be closer to 200 cc after the boring of the cylinder.... but not quite even that.....

You can get a Big Bore 240 kit if you want (from 500-600 bucks for the kit).... That's a different cylinder, head, piston and stuff that makes it rip..... 72mm Piston/cylinder (Stock bore is 66mm)

All indicators I can find say you should have a larger jet if you bore 40 or more over..... But it won't hurt it so much if tuned right, it just won't have its best performance....

.020 is equal to 20 thousandths.... of an inch. so yes,.... 20 over.

I'm not really sure why we couldn't all agree to say it's 2 hundredths over,... which would be equal in proper terms.... but I think it sounds bigger if you say 20 over..... That's probably why the reference always goes that way...
