letsgetthisdone Posted April 5, 2006 Report Share Posted April 5, 2006 I am at 2,200ft. elevation (Las Vegas, Nevada). The bike has T5's, .010 over wisecos and the Trinity 35mm single. It has a 190 main a 52 pilot and the needle is in the middle. It bogs severely from 2/3's throttle and up. I'm thinkin its rich but just want to make sure.

Dinner Posted April 5, 2006 Report Share Posted April 5, 2006 Have you tried screwing the air screw out to see if that makes a difference? Quote Link to comment Share on other sites More sharing options...
letsgetthisdone Posted April 5, 2006 Author Report Share Posted April 5, 2006 (edited) I thought the air screw was like the 0-1/4 curcuit . But it has to be the main that is rich becuase it doesn't do it until the cylinder head temp is 160+ if it is down around 145 (cylinder head temp) it will pull fine.

letsgetthisdone Posted April 5, 2006 Author Report Share Posted April 5, 2006 (edited) Just tried the air screw, turned out to 3.5 out from 1.5 out didn't work. Did not work. Thanx though. Anyone else have any suggestions. Edited April 5, 2006 by letsgetthisdone Quote Link to comment Share on other sites More sharing options...
scuba147 Posted April 6, 2006 Report Share Posted April 6, 2006 (edited) Try one size smaller on the main jet and see if that helps and if it is better work your way down. Alot of my buddies are at 178 to 190--190 with port work at 500 above sea level. When i bought my shee it was 5 sizes down on the main jet-165 and had to have the choke on for it to run right--i rejetted that day and have had the same main jet (178)in for 4 years--you will know when its right and do a few plug checks. I'm sure someone else will chime in on helping you out---I'm no jetting expert. Good luck. Edited April 6, 2006 by scuba147 Quote Link to comment Share on other sites More sharing options...
Wallynut Posted April 7, 2006 Report Share Posted April 7, 2006 What needle do you have? The 190-175 mains are the range to see about working in. You might want to try the old trick of pulling out the choke to see if worse or better. You could alsotry moving the needle to see what effect there is. When you said that you played around with the air screw, was there any effect at all? I would think that you should have seen some kind of change from 1/4 to 3-1/2, one end or the other should have shown something. Like scuba147 said, once dialed in, you won't have much need to adjust anything but the airscrew. Quote Link to comment Share on other sites More sharing options...
