50CC upgrade By grima (Read 626 times)

Okay, still working the uneven idle issue (getting into a pissing contest with Ice Bear about it, too) but I'm thinking a little further ahead. Specifically, I know my wife isn't going to be happy with 35mph. So, looking at upgrades. I love Scrappy Dog's prices and their stage 4 kit looks great, but I'm wondering about the results. Can anyone tell me what I could be looking at after installing it? Or has anyone done any of these upgrades before?

And before you say it, yes, I realize that exhaust will probably hit the rear shock. I think I can work a fix for it, though.

I think that is a lot of money to spend to get 5 more miles per hour. I would suggest putting in Taller Gears in the Tranny for about $50.00 dollars and you will get more than 5mph top end on it.

Just getting gears that have 1 More TOOTH on the Short Shaft and 1 LESS TOOTH on the Big Gear will give you 4-5 more on the top end. Going with 2 MORE and 2 LESS respectively will give you 8-10 mph.

Thanks for the info! I'm glad someone's looking out for my buck (besides me!)

Few questions, though... where could I get the new gears, do they need to be pressed/pulled and can a 50cc engine really handle the additional torque with the new ratio? I would think that new clutch springs would be required, at least. (To allow the engine to rev higher before loading it up). Does this conversion mean that acceleration would suffer? (Unless I could overcome that with new rollers). Anyone try this before?
