Adjusted the one tight intake valve on my 89, and figured that seeing that the Tupperware was all off, I may as well check the carb diaphrams. I had small holes in 3 of them---my bike only has 58K miles on it. I looked up Sirius and found that they were out of stock on diaphrams until the end of the month. While doing searches here on this site, I came across Snagletooth's message about using Plasti coat to make a temporary repair. Home Depot carries Plasti coat, so this morning I followed Snagletooths' proceedure and this afternoon I re-installed the sealed diaphrams. In addition to the Tupperware, both heat shields (the ones that are over each valve cover) were out, so it was real easy to change the spark plugs. Heck, I also found an open plug cap. I ordered replacements, but I took the bad one apart and convinced it to work by cleaning everything up. The resistance is a bit high (the resistor itself reads high), but it'll work until the new ones get here. Then the fun began. I started the bike up, and it sounded good when you opened the throttle, but it idled badly and slowly. I checked the carb sync, and it was all over the place. I synced the carbs (both on the right side were almost completely closed) and I had to slow the idle speed down quite a bit. I also had to adjust the idle mixture screws. Now it's idleing great. Those holes in the diaphrams sure had an effect on how the bike idled. BTW, I had adjusted the carb sync in May, and it was idleing what I thought was OK before I started on the diaphrams. Tomorrow morning I'll put it all back together and if it's not raining like they predict, I'll take it for a ride.

So last week I washed the bike a work. Fired it up and rode block down the street to fill up the tank. As I pulled up to the pump the idle got rough, dropped to about 600 and eventually died. i ended up pushing it to one of my employers other building. After 4 hours of trying to get it to run I gave up and left it for the night. Occasionally I would get it to fire, but it would never idle right nor would it idle over 300RPM. Next day, after work it fired up and idled. I could even twist the throttle and rev the engine. Shut it down, change the plugs. After changing the plugs, it idled smooth. The throttle was crisp. I went ahead and rode it the 70 miles home. It ran great! I did notice at idle it smelled rich though. Fast forward to today. I wander out to the shop to take the scoot for a ride. Hit the starter. It cranks for a few seconds then fires. idle was REALLY low. Let it idle for a couple of minutes and it dies. Now it won't start again. Anybody got any suggestions where to start? Thanks, Ed
