Default Project: PGO Bug Racer, simplified

And here we go again - go-kart #3!

This one is going to be based on the absolutely awesome PGO Bug Racer buggy. Obviously it'll be a simplified version, with less curves, less plastic, but hopefully still bad-a$$!

Got a start on the frame. All comparisons to the Bug Racer in my design are by eye only. I may make some obvious changes for the sake of simplicty or efficiency.

Bare minimum - 420cc 14hp Predator motor. Will be looking to build a few of these, hopefully using sled motors. A guy wants me to build him a 1 seater version (he's a big guy), and he'll be providing me with a 20hp Honda GX620 620cc twin cylinder motor that already has the driver clutch on it.

I'm gearing the kart torwards the $2000 market (for starters), if someone wants a big fancy motor - they can pay for it or supply it!

I think sled or motorcycle engine is the way to go for this buggy! Looking forward to seeing what you come up with!

something similar to the ones on the red buggy at the beginning of this thread. i think those are 25" tires, i'll be using 22" tires simply because the tires are crazy expensive. 22" should be acceptable.

New toys! I love Harbor Freight 20% off coupons. Hopefully these will make my life soooo much easier. I do wish I had a little more distance between the chuck and the base to accomodate the tube notcher, but I'm pretty sure that by swiveling the motor to the side I can still get the job done. Now I need a hole saw set! The one hole saw I had (3/4") is really long... I think Harbor Freight's set has much shorter hole saws. I hope...

It's odd - to change drill speeds you have to change the belt ratio by moving the 2 belts in it up or down to a larger or smaller pulley. Seems pretty easy to do though. I tried REALLY FAST, and r e a l l y s l o w. . .

Just bought a new Duromax 16hp 420cc motor with electric start for the kart for $290 shipped, and a Comet 40 (clone driver, Comet driven) for $224 shipped. That's a LOT better than the $650 (plus tax) that I thought I was going to spend!

The Duromax motor is basically the same as the Harbor Freight 420cc Predator motor, except I'm paying $80 less for it! I don't know about the 16hp rating, but it claims to have 21 lbs of torque. Hopefully it will make this big kart move!
