Well I decided to see if I can sort out the poor running on my RGV. Compared to a Kawasaki triple there is a lot of stuff under the fuel tank.
Been doing lots of reading and learning the last few weeks. These have a CDI and control unit that controls the power valves and air solenoids.
The power valves are 3 piece and these early bikes have the ones that are known to fail
Carbs are Mikuni TM34 SS and have a power
jet, pilot and main air bleeds too. From what I can learn the pilot air valve boosts air at certain rpm to reduce emissions and improve throttle response.
Not sure about this so I'm going to block the ports off and see how it runs. The main jet air boost is suppose to improve power so I'll leave that alone.
There are about a half dozen control units and some restrict power, some don't. I have the control unit 22D00 that was for the German market and
opens the pilot air valve between 2-6K. Best control unit is a 22D30 that only opens the pilot air valve between 500-2K rpm but my unit has the same
main jet air valve and spark curve so I'm hoping plugging off the pilot air valve will be a improvement.
I checked all the jets and someone must have put in a cheap rebuilt kit, most of the parts are not genuine Mikuni
Spent $225 today on
all the correct Mikuni brass and ordered 2 new fuel bowls two. While I'm waiting for all the parts to come from the UK I'll tackle the power valves.
You can get really trick ones that don't fail for about $550. I'm learning right away that these bikes are not cheap to get running right.
Hope to get the title for Ca. if all goes well when I hear back from Sacramento, if so this bike is going to be really tricked out. If not I'll
make another plan. It's a fun bike to ride at 306lbs and around 60hp when all is working right.
