Mike
You and I are two of a kind man! That post has me reliving my life, only mine was/is with the V rather than the DS and the Ford instead of the Dodge. Too funny, but true!
Okay, I need you gurus help with the new beast. I cannot get it to idle properly. We are running dual CV38's on this bike and if blipping the throttle it is slow to return to idle, and if the master idle is set too low, the engine will die. Started with 40's for pilots, had idle problem and was hard to start warm. With 45's has idle problem but is easier to start warm. Tried 50's and its worse than the 40's with idle and starting warm. No obvious vacumn leaks or clogged orifaces in the carbs. Any ideas?? I am totally stuck on this one as is Ray. Thanks guys. Ken

A lot of times the bigger cams will want to idle at a higher rpm because they have low vac signal below their power range. I usually have to idle mine up 200 to 400 rpm higher.

I think that the BOM is close on this one.
Ken, do you have any idea where you're idling at right now. 1200, 1800???? I know that the more radical the cam, the higher idle you'll need. Sounds to me like the BOM is right on. I'd would go back to the 45 pilot and bump the idle up to about 1800 - 1900 rpm. Just so that you know, with the Big Lectrons that we are running, we can no longer run the low (stock) rpm. We now run our RPM's at about 1800-1900 RPM. With that monster, I'm going to assume that Ray has some SICK cams in there. If the cams aren't too crazy, the big carbs have soooo much volume of air to make up, you may be seeing the exaxt same problem created by a drop in air velocity through the big carbs. I would doubt the latter to be the case, but it's possible.
Some of you DUAL guys chime in here.
It does sound like a leak though doesn't it.
Ken, you may have to bring it over and throw it on the lift so that we can really get a good look at what is going on.

WooHoo..... Its idling good now. Not sure if it was some new clamps on the intakes or some newer shorter style pilots, buts it where it needs to be now !!
Mike, get ready....
And call me with those dyno results! Thanks guys for the input!!
