Spent a little time in the garage today to do the last of the last of the last thing...for now. You all know how THAT goes.
Anyway, I tried the
DJ 170
main jet since I just ported the manifold AND I'm at 5600 ft. elevation, so I thought I needed to lean it out a bit. Seemed a little too lean, and I'd rather err on the side of richness, so I put the DJ 175 back in.
Here are the settings I have now:
-Ported manifold
-HK 3" pipes
-Speedstar air cleaner
-Speedstar ignition module (if that matters)
-DJ 175 main
-DJ needle at 3.5 (from the blunt end down- washer, circlip on 3, white spacer, 2 silver washers)
-stock pilot
-
PMS at 2.75
-Accel duration all the way down with nut flipped to reverse side
All the following was done in the garage, not riding:
-Needs the choke to start (40 degrees here now), and starts like a champ with it on.
-Once started and choke off--hesitation/stumbling when I throttle; popping and backfiring (from the pipes, not the
carb).
-Turn choke back on--smooth throttle, no hesitation at all.
I read through a bunch of posts, and I guess I'm looking for verification of my conclusion. I think I'm a bit lean and need to turn the PMS out a bit (1/4 turn at a time) until stumbling/popping/backfiring goes away. Then road test. When it's not flurrying.
I would have finished it off right then and just tried it...but I got called in to babysit.

Go ahead and laugh...
Anyway, gonna go back out in a few hours and try and polish this off. Does it sound like I'm on the right track?
Thanks,
RK
