Hey all, need a little help from the community of twin straddling gurus. I've been working on a chop project for about 2 years now. It's almost all together now and I'm just chasing this damn tuning rabbit all over the garage trying to get it nailed down. It's a '75 motor with headpipes lengthened about a foot with 1.5" pipe, keihin PWK's with pod filters. I've been trying to get these carbs dialed in for my mods and altitude(4500ft), but have been having a hell of a time getting them right. First it had a hanging idle problem, and seemed a little rich so I rejetted it with a leaner(30) pilot. Then it was revving to high hell at idle, so I put the original pilots back in it, but still had a really high idle problem. Well after adjusting the mix screw a half dozen times(which is a real pain in the ass with the right side mix screw in the middle, btw) and couldn't get the idle to come down. SO, for shitzngiggles I pulled the starter fluid out to check for leaks again and sure enough the RPM's dropped when I hit it with the starting fluid...
So my Keihins have an air leak, not sure where yet exactly, I had to pack it up to head to class, but when I get home and pinpoint how do I fix it? I can't imagine it being a cracked boot since they're brand new with new gaskets and all, so is there a silicone spray I can use or what? Any help would be totally appreciated. Suggestions on jetting specs would be nice too!
