I have owned 3 electric carts and one gas powered 2 cycle EZGO golf cart over the past several years I recently sold my 03 EZ GO PDS and am thinking about a newer gas(06-08). I am an old motorcycle racer and engine builder both 2 strokes and 4. I am looking to get about 25 MPH out of a gas engine cart without changing the motor. I read on the forum about adjusting the govenor but that many of the engines will easily overrev. I also read that they sell hi rev kits for some motors but I have not seen them for sale. Does anyone know whats the best rout to go on this as to what brand of cart and where to find performance parts. I know a lot of people put bigger rims and tires to pick up a few MPH. Also what do you guys with the fast carts do for brakes?
