Very rainy here. I missed out on all the fun of flooded roads on the DR, because of work.
Managed to tear into the carbs again.
The CV carb was working but clearly lean on the idle circuit. I'd left the idle as-is but upped the main jet, and raised the needle to highest clip position, and it ran well, but obviously missed some power on the lowest revs where still a bit lean. It would stutter a lot on low revs until warmed up.
The (non-pumper) TM carb didn't work when I last removed it having messed with it.
TM has a new jet needle that it fractionally (1mm) shorter than the original damaged one, but similar FP taper. That taper is half the problem though I think.
I've upped the idle jet a couple of sizes in the TM, and put the larger main jet I know worked in the CV.
Above 1/4 throttle or so, all good. Idle all ok after turning in the air-fuel screw a tad. Stutter very difficult to ride around at off-idle to 1/4 (effectively 2k revs to 3.5k revs).
I had to run an errand which involved a test ride, and riding around a stutter at off-idle made for interesting riding in rush hour traffic. Idle was okay, an at 4k or above it was powerful as you like. Just getting over that 2k-3.5k bit in traffic was rough.
My money's on raising that jet needle to its highest clip. If that doesn't push the stutter out, then it'll be swapping the needle taper and starting all over again.
