Marvin Martian's Motorized Madwagon Makeover

Just came in from the first run with the new setup and can't seem to wipe the stupid grin off my face The new goodies are: 18mm Mikuni carb flowing thru custom (aka homemade) intake manifold. 67cc BGF motor with piston skirt trimmed to clear intake port. The exhaust pipe is as close as I could get to the measurements spat out by JavaPipe-Tuned Pipe Design program. I still need to make a muffler, as you can tell if you watch the video. (I'm pretty sure the neighbors hate me already) Once the muffler is on I will have to tweak the jetting/adjustments on the carb, but it seems pretty close right now. I can't figure out how to post the video so here is the link to my photobucket page. The video is on there, if you're interested. It's called throttle tuning. Hehe Hehe.

I watched the vid, pipe sounds cool! Good job Marvin!!

I'm interested to hear how you make out with the 18mm carb after you get some running time in...18mm should give you all the revs you'll ever need

Thanks, Rockenstein, I'm starting to wonder if I should have used a higher max rpm in the javapipe program. I used 6000. I don't know if a 67cc want's to rev much more than that with the stock porting, though. The good part is that even with the 34 tooth gear and my 300lbs on board, the thing pulls like a tractor from a way lower rpm than my old motor (50cc) did.
