jjven68 Posted March 22, 2015 Share #1 Posted March 22, 2015 Hey guys here is one i can't figure out. After taking the carburetors out and throughly clean then and putting them back on, the bike takes several long cranks to start. Fully choked once it starts and warms up it will hold idle (although a little high) for just a few seconds a then died. Is almost like gas stops flowing into them. I disconnect the pump, which I tested and is working correctly, and connected an auxiliary tank straight into gas intake of the carbs with the same results. As long as I keep reving it stays on. But if I stop it dies after a few seconds. Any ideas? Link to comment Share on other sites More sharing options...

jjven68 Posted March 23, 2015 Author Share #3 Posted March 23, 2015 Thanks Peder...I have been looking for the pilot screws setting. Any idea? Link to comment Share on other sites More sharing options...
Marcarl Posted March 23, 2015 Share #4 Posted March 23, 2015 Pilot screws setting start at 2.5 turns out from bottom. Did you clean them as well, or could you not find them? Vacuum leaks are also a 'look at', but my guess would be to check the sync on all four. Often times people want to adjust the idle, look for a screw to do that with, find one and end up turning a sync screw instead,,, and yes, turning on a sync screw will adjust the idle somewhat, but do nothing for the overall picture,,,, and these motors will run amazingly well when they are out of sync.

jjven68 Posted March 23, 2015 Author Share #8 Posted March 23, 2015 well I guess after taking out and cleaning the carburetors 3 times you don't have any other options but becoming good at it. Haha!! Its funny you ask because I think I came up with a very simple an awesome tool for the job. I took one of the bristles from my large metal brush and unbended it from the middle to make it longer. It happens to fit the hole of the pilot jet just perfect and it is hard enough that you can push it through it and take out any obstruction. Highly recommended.

Peder_y2k Posted March 23, 2015 Share #9 Posted March 23, 2015 I use a single strand of copper wire from some 16ga. wire. Soft, yet stiff nuff to do the job. Pete, in Tacoma WA USA Link to comment Share on other sites More sharing options...
jjven68 Posted March 23, 2015 Author Share #10 Posted March 23, 2015 (edited) Hmmm never thought it would be stiff enough to go thru. I will add it to my tool box. By the way what is this jet? The one left of main jet. Can't find it anywhere. You know? Edited March 24, 2015 by jjven68 Link to comment Share on other sites More sharing options...
