My friend is running a streamlined xr500 on the salt very soon and things have turned for the worse as he can't get the 38mm Lectron flatslide carb to pull off idle on the dyno, even with Fast By Gast tech help. He has dyno time scheduled tomorrow evening, and I told him I may be able to get ballpark jetting and a Mikuni together for him. I have a 36mm and 38mm Roundslide VM and quite a few jets.

Can anyone put us in the ballpark for jetting?

Anyone put us across home plate with Bonneville jetting advice?

Thanks,
