    Well I finally decided to start over with the carbs. Could never get the idle right and it always had some sputtering on decal. Since the exhaust is not really much louder than stock and I went back to the stock airbox, I figured that the stock #95 jets just might work. Got them in today and guess what, it runs like a top! Have the fuel screws out 3/4 turn and started with the air screws out 1-1/4 turns. Got each carb adjusted and then synced them all. Runs very strong all thru the rpm range and idles great! Still have to do the plug chops to verify that its not going to burn itself up by being too lean. Wish I had started with the stock jets a couple weeks ago! Oh well, live and learn!

      What more could you want? That's the way I judge every bike.

      2016 XL883L sigpic Two-tone blue and white. Almost 42 hp! Status: destroyed, now owned by the insurance company. The hole in my memory starts an hour before the accident and ends 24 hours after.
