I was looking at another thread. Here https://www.fireblades.org/forums/hon...to-shorty.html
Concerning the video. My bike makes the same black puff when I get on the throttle good or just rev it hard the same as he does in the video. Is this common on these bikes? Is this just a rich condition? Does this mean it needs tuned or is this normal?
Yeah, I have the same thing as that guy... Wait a minute, I am that guy!
I think I am running a tiny rich at the moment. Not wnough to hurt anything, but as soon as I get my HTEV Eliminator I am gonna have the map tested and retuned.
I think the puff of smoke is from the Accelerator pump feature on the PCIII
. The tuner said that he uses it on some bikes if they need it.
he had it on the dyno and had the A/F dialed in perfectly, but he showed me when he goosed it how it leaned out for half a second, and then he turned that on and it stayed at the proper ratio when he opened the throttle.
Some bikes it really doesn't make a difference on, but mine it did.
I dunno though. I had the map made for a different bolt-on can, and then I through on the Yoshi and then cut it down without retuning it, so it may very well be off, but not by very much or I would notice it when driving it.
