I did the UTB 3 weeks ago. As far as I remember there are 2 screws available only for adjusting the throttle buttefly valves at 4200RPM. One screw adjustment for cyl 1&2 and another for cyl 3&4. There are 4 air screws in which you adjust 3 of them in order to match cyl #3.
I tried to adjust cyl 3&4 then 1&2 at 4200 RPM then I adjusted the 4 air screws at idle.
I got them all fairly close to each other @ 4000 RPM but I found that the vibration just shifted from 4200 to the 5200 RPM range. Am I doing something wrong?
Should there be 4 adjustment screws for each throttle body butterfly adjustment ? I only saw 2 and they appear to be interlaced.Pictures showing the adjustment screws for the buttefly vaves would be useful.
I later installed the PCIII with the Wally Map. Found the throttle to be very smooth and more linear. Better yet, I find that my FJR doesn't get as warm as before. With regards to the vibration I dont find that the PC III makes much of a noticeable difference. The PC III has improved the heat issue and improved the throttle response.
Am I missing something here
