Well after a long winter hibernation, I started the bike and went cruising. And to my surprise the engine is giving me a hard time.. even though no changes were made over winter. At first I thought it was bad fuel, but there was very little fuel in the tank and I filled it up with fresh fuel which surely diluted the little that was in there.
Basically the engine quits in neutral. As long as I give it gas it goes, and goes strong. But if I squeeze the clutch, as soon as I let go of the throttle the RPMs drop to a stop. The throttle barrel needle, even when turned in all the way, does nothing. So I turned the throttle adjustment screw (top of carb) counter clockwise for more open throttle at idle. That did give me a way too high RPM at throttle, but even with that it slows down and cuts.
My mixture E-clip is at the top notch and I currently have a 0.61 jet (this setup stopped the 4-stroking I had experienced last year).
Are these all symptoms of a too lean setup?
these are symptoms of the gas that was left in the bowl of the carb over winter turning into lacquer. Take the bowl off the carb and clean it out along with the jet and float needle.

For drilling, this set is awesomeFinally got around to jetting. Looked for a little bit on eBay, couldn't find a jet set 65 to 70 in increments of 1 so i tried the solder shut and drill out. Got the $3.99 micro drill bit set at harbor freight today. I measured in mm since it's a Chinese carb and bad conversions are what took out that space shuttle that one time. The kit says .5mm .6mm and .8mm. seems this wasn't what was in the kit at all lol. The biggest bit i could fit through the jet measured .56mm. my next biggest bit in the set measured .76mm but wouldn't go through the hole in the jet. So i soldered the jet shut and went with the .56mm thinking if it's too lean I'll have to ream the hole a little or break down and order a legit jet set. Took her for a cruise and so far it's way better. Runs smoother at low rpm and revs higher easier than it did before as well. Wish i would have done this a long time ago. 1355' above sea level is my attitude of anyone is wondering. 72 degree semi humid day for the weather. Rooster crowed 3 times this morning, he usually just does 2.
