The 99101-393 look to be correct. They should be 8mm top to bottom. They will also come in the sizes you need...

Thank you WG, this will end my frustration..or perhaps begin it I will be sure to post back with my results once I get the jets installed.

Well, here goes nothing! Just picked up and installed #98's and reclipped my needles to groove 4..air screw is still at 1 1/4 turns. My ride home will be my test ride. I also picked up some 100's if the 98's are still a bit lean.

I ended up with the 100's in my carbs, needles 4th groove. Amazing the performance difference!! Thank you WG for your input to this subject.

I sent a set of 102s to a customer a few days ago and am awaiting some feedback. Glad the 100s did the trick. I suspect 102s will be fine as well. I will pass along the reclipping of the jet needle. It would have been better to have tried one thing at a time to assess the effect of the change rather than changes but if it runs nicely now, that is a GOOD thing!

Initially I tried the 98's with the needle at the third groove..not bad, but still had some hesitation. Installed the 100's with the needles in the third groove, improved, but still a tad of sputter around 1/4 throttle. Reclipped to the 4th as you had initially suggested, viola, no more sputter, excellent throttle response, and a set of plugs that burn very nicely. Using 102's with the needles in the third groove should work just fine though.
