I think a lot of the idle problems come from using the larger 14mm bing. You may be able to better top speed out it but its idle circuit is too rich. In the wiki they call the jet holder which is weird but that part comes in numbers like a jet. I believe 14 and 15 bings run a 2.22. If you have others bings you might want to try a different jet holder but keep the same jet and that might help the problem.

Here at 77 we've better luck with stock cylinders we've had better luck 12mm bings and SHA's. They actually went faster and wanted to idle. I think it all has to do with the idle gas/air mixture.

16 PHBG is good choice too because you can tune them more easily. It's an expensive option though.
