Many of you here have met my son Joe over the years. He has always been a good kid. He has always had a knack to all things mechanical... to the point where now, at 13 he does all my small engine maintenance and repairs. Hard thing is to keep him from modifying it ;-). About 3 years ago Ann and I got him and older full suspension go kart, a Foxfire 620. It is not made anymore. It is too heavily suspended an underpowered with a 6hp mitsubishi motor. Good gear, just not enough for this cart. About 1 year ago Joe took off on a quest to modify it. Here is a list of his mods, all done by him, all his ideas and work.
- Mount 36 MM Mikuni carb (we had an old Honda ATC sitting in our junkpile) He removed it, cleaned it, found an adapter on line and mounted it.
- He used parts from the ATC and some leftover parts from my jeep days to get it all hooked up with a custom air filter assembly.
- He mounted the rear tires on the cart, cause you know more clearance and bigger is better ;-)
- When he first launched the modded art it shredded the torque converter belt every 10 minutes. He found on line a "Torqueanator" upgrade, saved his money, worked his tail off to earn more and bought it.
- At this point, the belt shredding ceased.
- Top speed rose from 18 MPH to 30 MPH!
- That excessive speed led to the stock front axles breaking. Thankfully we have a cousin is a machinist and custom made him some heavy duty proper front axles. Super beefy, quality metal.
- He also mounted some new to him rims with some taller tires on the front.
- He built himself a custom exhaust, using a cheap spark arrestor, and some exhaust tubing I had laying around. Nice throaty growl.
