Title: 50cc dirtbike question
Post by: DeeJRedE on August 03, 2007, 12:22:05 PM
I picked up a small 50cc dirtbike, its made by Madami the model is a pb50jr. I can barely find anything online about it, but its got a small mikuni carb with one jet. I was wondering if anyone might know what the jet size might be? and/or what size i could rejet it to. or even where to start looking to find out. Its a peppy little thing, but everyone knows you always want to make it a little better than stock. Anything else i might be able to do to get gains out of it?

Probably uses a LIFAN engine. If you'll google on that you'll probably come up with the information your looking for.
