Hey everyone! I bought an '82 QT50 in March and have been tinkering around with it and got her running pretty good. I have a few friends with bikes and we ride together quite a bit and they are a little faster than me, so I decided to buy a performance exhaust =) and have a few questions about jetting and stuff once I put it on. First of all, does anyone have a QT50 with a MLM People's Pipe on it? Here is a link to it, I thought it was pretty sick and would be a good choice http://www.1977mopeds.com/product/50472
I want to know what size jet I will need to put in it to run it with this pipe. The entire bike is stock right now and this will be the only mod that will be done to it. Another thing I was wondering about is if I change the jet size, do I have to mess with the automatic oil pump or will it be fine? Any insight on these two things is greatly appreciated!
