Tuning with A/F Gauge, Continued
Posted: Mon Apr 02, 2012 9:58 pm
I'd noticed recently that I was getting a stumble off idle when taking off from a stop sign. I suspected that the bike was going lean at the transition from idle. Tonight, I connected my A/F gauge and tuned the pilots a bit.
Here's the baseline, before tuning. You can hear it tapping away, hunting for idle and you can see it go lean just off idle:

Here it is midway, after tuning cylinder's 1 through 3 to two bars toward the rich side.:

This is the final result, after richening and balancing all four cylinders. I still need to sync the carbs, but it seems much improved:
