Re: Need Suggestions
The main jet works between 3\4 throttle up to full throttle.
If it is too small(lean) it will not operate correctly at the throttle settings i just mentioned.
Bigger pistons will require "A" bigger jet. How much bigger? No definite answer. You need to take into consideration, your altitude, humidity, what did it run good with before, what mods have you made since then,.....and so on and so forth. Its basically hit and miss, unless you can find somebody that has the same bike with the same mods as you. Thats rare, but its happened to me before , and i got my jetting perfect.
