im making a petrol scooter i have a 26cc 2stroke engine and im wanting to know what sprocket ratios would be best i have the scooter but i need a new back wheel cause the one on it now is belt driven (the scooter used to be electric) and if anyone knows where to get a wheel with a sprocket on it i would appreciate it

Well, I'd be thinking about some sort of clutch if this is not a suicide scooter!

nar i have an accelerator for it and if i am not using the accelerator it dosent move the drive shaft lol

Is this a chainsaw engine? I can't think of many others where the shaft (sprocket?) don't turn unless the accelerator is pulled. A chainsaw has a clutch on that sprocket.
It seems to me a standard bicycle deraileur could be mounted onto a wheel and also gives some gear options.

The following is a link that may help - but since you said 'petrol' I'm guessing you're not in the USA, so it may not help.

Google - Go Kart Sprocket Wheels - should get a load of hits. Good luck.

Im also making one ,this is the wrong forum for that but seeing how your buzzer only has a displacement of 23cc and more rpm related power around 7 or 8 x 1000 rpm id be thinking a 1/12 ratio for the chain torch converter ,i couldn't give you a suggestion on what size tire but not much bigger than the end of your drive.

Iv owned one of these engine's from a goped ,a RC 23cc with a unknown bore size after market carb and many other goods inside the engine i did not purchase but the guy at the repair store said i had a very after market engine ,they have not much torch they are all rpm so don't be expecting a fast machine from one of these unless you plan to throw 500$ into a remote control airplane engine and weigh a 50 pounds. Yours probably has 1.? hp depending on the brand and age ,you might want to get a cheap compression meter to see if it's even worth it because if you just put it on with crappy compression ,it will start but die out every time you get on it.

This site seems to have a load of information, and a bunch of useful parts. One of these installation manuals might provide some hints about problems.
