Update on the Treefrog....
Cruddy HarborFreight Handtruck tires are shredded wheat. (Imagine that?!?!....) Everyone loves this kart and that's why the tires lasted just one season! SOOOOOooooooo.... I've been looking to put slicks of similar size to their destroyed counterparts, and I'm using the Clone/Torq-a-Verter combo on it. I'll have to move the motor back 6" and raise it about 2" (which shouldn't effect the handling too much) and I'm swapping the final drive to a 4>1 ratio.
This will give a 10>1 starting ratio and still allow the kart to top out at 37 mph with the governor still hooked up. But, as discussed in other parts of this forum, I'm going to cave in to temptation and mod the motor with better exhaust, better air-filter, and re-jetting for proper mixture.
This will all be limited by Time & Money. (Like ALL things in the Known Universe)
