Re: <strong>Weber</strong> <strong>32</strong>/<strong>36DGV</strong> <strong>verses</strong> <strong>the</strong> <strong>Weber</strong> <strong>38DGES</strong><br />

That, I also believe and, in fact, have "tuned" my engines many times to just remove enough "ping" that I couldn't<br />
hear it.<br />
I've read recently that sometimes you can't hear pinging even though it's going on -- on a motorcycle jetting/tuning page.<br />
no way, a digital camera?!?<br />
or even better, a 1987 holder for <strong>the</strong> GNARLY4X license plate?<br />
Re: <strong>Weber</strong> <strong>32</strong>/<strong>36DGV</strong> <strong>verses</strong> <strong>the</strong> <strong>Weber</strong> <strong>38DGES</strong><br />
Your ping is directly related to <strong>the</strong> jetting, that's what got you <strong>the</strong>re in <strong>the</strong> first place. If you cause ping with a <strong>Weber</strong>, <strong>the</strong> indicator<br />
is nasty white plugs if driven within that range for a short period. Yes, <strong>the</strong>re is a chance you have carbon deposits causing <strong>the</strong><br />
noise, maybe even from playing with <strong>the</strong> jetting. Sometimes when tuning I just resort to swapping in a new set of plugs to final<br />
test mixtures . Occasionally, you get a surprise....<br />

You could be right, but in my experience, a ping occurring from a dead stop and lugging <strong>the</strong> engine is usually caused by an<br />
ignition timing problem, and especially in a vacuum advance/centrifigal disty. A ping occuring at high RPMs under load can be a<br />
fuel/air mixture issue.<br />

Again, perhaps, but with Yodta's driving style, I'd say <strong>the</strong>re probably ain't much carbon on <strong>the</strong> top of <strong>the</strong>m thar pistons.<br />
