had a bunch of personal carts over the years, a few of the CC's I've belonged too didn't allow custom carts, Rancho Murieta, Blackhawk, Oakhurst, some have since relaxed those stupid rules...
I still would do some stuff, bigger mag wheels, wider tires, some engine mods, a few decals, radio, heater & cooler side mount & club/ball-washers too etc., my last Yamaha gas cart went about 30mph, better clutch, wider belt for the drive, ported the head & did a performance valve job {they have a crappy valve-spring}, made a non restrictive straight intake out of 1" exhaust tubing {far less restrictions}, made a free flowing 1" exhaust split so it had duals out the back {with out all the chambers, like the stock muffler/exhaust} wasn't really that much louder at all, I used a K&N filter off an old motorcycle, 30mph after all the mods with 2 x 250# golfers cart bags full of crap & full coolers, it would only go about 12mph before...
I wanted to lift it, it wasn't allow then & that was too obvious, I would have gotten fined & in trouble "Yet Again"... as soon as I sold my place they changed the rule, my neighbor bought my cart he lifted it & put a long arm suspension & coil overs on all 4 corners, said he was going to do disc brakes too off a quad... I haven't seen it since just after the lift & suspension mods...
