Hi I'm new to atv's and I want the max out of my blaster. so what all can I do to a blaster engine to get the max hp without using anything more than 92-94 octane fuel? I like to ride long distance and mess around occasionally. I have no intention on racing other than when my buddies think they're sweet. I was thinking about a hotrods +4mm crank, vito's BB sleeve, wiseco BB piston, vito's hemi head, local shop port, bore, and shave job and jet job with a 4 degree advance on timing. Any advice would be greatly appreciated thanks everybody.
