Well motorgeek then it is time to develop an adjustable main jet on the handlebars ....
and be a millionaire $ $ $ $ $ $ ;-)
I could become a millionaire by making an adjustable main jet on the handle bars if I also owned a piston company. I would make my millions selling pistons not the adjustable main jet apparatus.
The majority of the riders would not have any more success tuning with an adjustable main jet than the guys that are using tools to change jets. You need turning experience and a way to gage performance when optimizing your jetting.
