Still working on getting my project back on the road, and I've finally reached the point that I know I need some help from the group. Here are some background details:
'88 1127
Pre-750 Carbs w/ factory pro jet kit (32.5 pilot, 15mm float height, 107 107 112.5 107 mains, 2.5 turns A/f screws)
Post 750 ignition system (including CDI)
At the settings above I can get it to idle if I am delicate with the choke and throttle. Once idling it is mostly responsive to the idle screw and will stumble and sound rougher when throttle is applied. Pulled the plugs and numbers 1 & 2 look fairly wet & a little dark and numbers 3 & 4 look normal.
My first thought is a need to try a vacuum sink which I will try to do as soon as I post this. Figured this is something that could make a 1 & 2 vs. 3 & 4 difference. I've tried some various things recently and 1 & 2 always seem to be more rich than 3 & 4. Infared thermometer confirms 1 & 2 are not firing as well as 3 & 4. Everytime I have had the carbs off and back on I would bench sink.
Bike has new engine intake boots and seals, and new rubbers on the airbox side also.
Stock electrical system which was running just fine before the project started...
I know there is more information I probably need to provide, but thats half the reason I wanted to start this thread. Need some input from some more experienced people.
