bongobobny Posted August 1, 2012 Share #2 Posted August 1, 2012 Pretty much just remove the 4 lines and cap the vacuum ports off... Link to comment Share on other sites More sharing options...
jasonm. Posted August 1, 2012 Share #3 Posted August 1, 2012 Pretty much just remove the 4 lines and cap the vacuum ports off... But remember they are capped. I had caps dry out and crack on a YICS bike in 1 year. Quality caps are an unknown quantity. So caps need to be inspected often. Link to comment Share on other sites More sharing options...
Venturous Randy Posted August 2, 2012 Share #4 Posted August 2, 2012 (edited) I capped mine off several years ago and the bike ran better and my gas mileage is better. I have had a problem with the caps having the top come off, and it is always one of the two that are the hardest to get to. The next time I have good access to them, I am going to put a short piece of hose on and put a plug in the hose. I believe it will last a lot longer.

Tkosanic Posted August 2, 2012 Author Share #5 Posted August 2, 2012 What size caps do I need. I would like to pick then up on my way Home. Do you by chance know the size of the E-clips for the throttle tie in rod and the choke tie in Link to comment Share on other sites More sharing options...
Power Trippin Posted August 2, 2012 Share #6 Posted August 2, 2012 Just curious why you would want to disable the YICS? Is it a fuel mileage issue or do they actually run better? I have mine still hooked up, bike runs great, gas mileage around 40, idles good, can't complain a bit. Link to comment Share on other sites More sharing options...
Condor Posted August 2, 2012 Share #7 Posted August 2, 2012 Just curious why you would want to disable the YICS? Is it a fuel mileage issue or do they actually run better? I have mine still hooked up, bike runs great, gas mileage around 40, idles good, can't complain a bit. On older bikes the possibility of air leaks is greater with the YICS hooked up. Sometimes it helps to disconnect it. On the '83 there is one hose that needs to be left alone from the #2 carb to the booster. Should always be checked and replaced as needed....
