Need help on parts

[notch65s]

Hey there, i purchased this kit to get into my jap import 50s and need help on which crank to buy


www.sip-scootershop.com/en/products/tuning+kit+malossi+sport+112cc+_10304000

also which primary gear would work best for me

i am only 55kg so very light and would like to be able to cruise on 100kph or 62mph. i didn't wanna go to 130 cause i thought i didn't have to open the case but now it seems that i have to to change the primary gears anyhow, but its too late to get a bigger kit as i have purchased the malossi 112cc kit.

links to the best Crank and primary gear would be great to cause i am hopeless on the SIP website as i have no idea what im looking at.

HELP

Thank you so much for any help

Cheers Michael

62 mph is unlikely on any 112. (45ish at a guess)
a 125/135 will do that on a good day if everything is setup to perfection.

a 112 MIGHT do that if tuned to near the limit

I'll presume you're not changing the ignition so if so then you'll be looking at a small taper crank with 19/20 cones and 43mm stroke. 100kmh cruising speed isn't really going to happen with these old trolleys without spending a lot of money and/or time. If that's the be all and end all you'll need to look at something more modern or spend big.

i am willing to change anything to find power, thats why im here to find out what to do/buy to give me extra power. i have read on here people doing 65mph when they weigh more than double me so it has to be possible.
