I reckon i can handle the pocket bike exhaust mod no problems. I'll have to go check out this handlebar idea too.
Do you know the actual name of the mikuni clone? so i can do a bit of a search for it? and what was the filter you had on it?
I saw a post somewhere about modifying the stock exhaust by cutting it and joining it back together with copper pipe. He said he got a few more mph by doing it. I like the look of those pocket bike exhausts tho. I might try modding the stock one while i wait for the new one to arrive.
At the moment i dont know what a reed even looks like so I'll go do some learnins on that.
