I have seen some problems with the following scenario that happened
to me.
After installing a set of Bub Jughuggers my bike ran fine without rejetting.( I still had the stock airbox on). Then I purchased the Ultra Flow
airbox and a Dynajet kit along with a set of block-off plates to de-pair
the bike with.
After installing all of the above items, I used the 195 main jet, Dynajet
needle and spring with the "e" clip on the 3rd notch. Bike ran great but when 1st giving throttle there was a blip or stumbling point as I went from an idle to take off. After getting up some RPM's all was well in the rest of the gears.
So last night, I tore bike down and installed the SCain A/F screw I purchased from him last fall. I followed his instructions for installation of his screw and set it at 2 & 1/2 turns out. I also moved the "e" clip to the 4th groove and re-assembled the carb and bike.
Fired bike up and it's never ran better. :twisted: :twisted:
I guess the point I'm trying to make is two-fold.
First, just moving "e" clip from 3rd to the 4th notch made a world of difference.
Second, the SCain fuel screw is an awesome way to be precise in
getting the right amont of turns on the A/F screw. That D-tool that came
with the Dynajet kit is worse than horrible! I never was really sure if the tool was actually turning the screw or not. :? Also, from now on, I can adjust the A/F mixture with out disassembling the bike.
I dont know if SCain is still making the screws or not, but I would have to say that his screw is one of the best add-ons I've purchased.
