At idle my bike doesn't seem to run very smooth. I would think that it should sound like a smooth hum, but it sounds like ba bum ba bum ba bum. Sorry, that's the best I can describe it. Right now I have Sato exhausts and a power commander, which I believe has the proper map since I bought it from Dan Kyle, (I really don't know anything about the Power Commander) and I did the flapper mod. I bought the bike about two weeks ago and it was completely stock and hadn't been ridden since 2003. (1600km) Even though the idle doesn't sound like I think it should, the bike runs very good. Is there problem with the bike, or is this normal?
I'm in Calgary too.
I have Yosh TRSs and a PCIII.
It has been custom mapped, and idles smooth.
When I ran LordDuckHunters v-4 Moriwaki based map it ran very well and idled nicely.
Have you synchronized your PCIII to your ECU ?
If not, that could be at least part of the problem.
Which Dan Kyle map ?
If it is his 2002 map that was based on the original large bore Satos, it is a max power mapping that is too rich for normal street riding.
Download the map to your laptop or PC.
Look at the notes.
If you see A/F comments about low/mid/high and full and numbers from 12.7 to 12.9, then you have the rich max power type map.
Worse yet, that dyno work was done at sea level. We are at 3500 ft. The ECU absolute air pressure corrections for air density are not perfect once you get too far away from the altitude the dyno work was done. (I think that intake flow inertia vs inlet friction losses is part of why this is.)LordDuckHunter has commented in the past, that 4000 ft altitude difference is the limit from dyno work to useage work, if you want sharp fueling.
You may have got a PCIII with nothing more than their standard PCIII map in it, which is not that good.
Do you have access to a laptop or PC?
Are you familiar with this stuff ?
If you want help, PM me, and you can come to my house and I can help you with it.
If you want LDH's very good map, I have it.
If you want a copy of the custom map that Ben Wheeler at Redline in Calgary did for me, just say so. It's free.
