DirtyFitz Posted October 2, 2006 Report Share Posted October 2, 2006 Well I used the knowledge that I got here on the site and got my bike running good but my bike doesnt want to idle and im lookin for a little help. Temp: 75-85 degrees Elevation: 2100 ft Ratio : 32:1 Pilot : 25 Main : 280 Needle : 4th groove Air/fuel screw: 1.5 turns out Just trying to get my bike running tip top for Dumont on Halloween.

2003LimitedBanshee Posted October 2, 2006 Report Share Posted October 2, 2006 Well, I know it's not the question you addressed but first, I would guess you are a bit lean on the main. I would expect you to be around 300 or 310. You can see my jetting specs in my sig, and I am at 2000 ft elevation, so no big differences there. Now, I am running an open element filter (no airbox) so that accounts for some of the difference, but I still think you would be a bit bigger on the mains. As far as idling goes, I know it sounds dumb, but have you checked your choke tube? I can't believe how many times people will miss this. From their, I would try going in a bit on the air screw, say to 1.0 turn out or so. I went up to a 27.5 pilot at one point, but ended up back at a 25, so my guess would be some additonal tuning on the air screw. Quote Link to comment Share on other sites More sharing options...
DirtyFitz Posted October 3, 2006 Author Report Share Posted October 3, 2006 Choke tube as in the choke itself? It wont even idle with the choke all the way out. Quote Link to comment Share on other sites More sharing options...
2003LimitedBanshee Posted October 3, 2006 Report Share Posted October 3, 2006 No the choke tube is the actual tube that goes between the two carbs. It is a small piece of approx 3" long vacuum tube the sends the choke "signal" from the left carb (sitting on bike) to the right carb since it does not have a choke stat. Look at your carb with the choke "knob" on it. Now imagine how the choke runs through the carb, on the exact opposite side of the left hand carb you should see a small piece of vacuum tubing that goes to the right hand carb. If you are missing that, you've found your problem. Quote Link to comment Share on other sites More sharing options...
