Hello folks,
We (both my wife and I) could sure use some help with her 96' ST carb issue. We purchased a 95/96 ST from a co-worker who seldom rode rode the bike as it has 21K on it. It started with choke "on" and seems to have the idle circuit plugged from sitting even though he ran Stabil at storage time. After warming -up it runs great but only problem was a cold start and idle until warm. So, we purchased the bike and thought I'd pull the carb's with a pilot jet plugged as it ran fine after warm. Just for grin's I pulled the plug's and checked the fuel filter, air cleaner, sub-filter and all looked good. I di check on a cold start to the exhaust temps and looked like cylinder 1+3 were colder than 2+4. So I'm thinking the pilot jet on 1+4 are plugged and go through with removing the set. After removing all of the pilot screws, they seemed to be clear? I bit the bulit and ordered the "Air Screw adjustment tool" that wad "D" shaped hoping this is the only other spot for a clog? The bike runs great after 12-1500 rpm and good after warms-up. Does seem like the idle screw is in "clockwise" to idle and when shifting through gears the tach speeds up about 4-500 rpm. Also, stupid question, but, what does the air-cut diaphram/valve do? Holy smoke's, thought I knew something about carbs but throwing me a new bone! Sure would appreciate any ideas! Thank you very much!
