Take the top off the carb. Make sure the throttle slide is clean with no varnish and no burrs or rough spots on it. I take them off and polish them with "0000" steel wool. Also make sure the slide channels in the carb housing on either side are clean and clear of obstructions so the throttle slide can move up and down easily. Put a couple of drops of 30 weight oil on the slide before you put it back in.

While you have the carb top off, squirt some WD40 into the throttle cable and hold the cable end up so you can lubricate as much of the throttle cable as possible.

When you cleaned the carb, did you find and clean the "Idle Jet"? It is located in the aluminum carb housing in the opening that goes on the carb intake pipe. It is just under the vertical brass tube in the aluminum carb housing. You have to look into the engine side of the carb opening and tilt the top of the carb slightly away from you to see it. Squirt some WD40 on it and blow it out with compressed air. I use a tiny drill bit #74 to clear the gunk out, but I DO NOT drill it.

Does your carb intake pipe have the plastic cup shim. It may have come off with the carb, which is OK as long as you put it back. The bike won't run properly without this.

Also WD40 or grease the throttle slide on the handle bar. Twist the throttle and look under the throttle handle and you should see a little slide moving back and forth as you twist the throttle. Grease this or squirt some WD40 on it. Don't get WD40 under the rubber throttle grip. Also squirt some WD40 down the throttle cable from the top end. Don't take the cable out or you may have a tough time getting it back because of a frayed cable end.

Last thing is to start the bike and have it on the center stand. Use the adjusting screw on the cable just before it goes into the carb top to shorten your cable length a bit. It will make the engine run at a higher RPM so you may have to adjust it a little at a time cold and hot until you get it like you want.

Depress the choke lever on the carb. Twist the throttle, the choke lever should pop up freely.

Let me know if these things help.

Thought of one more thing. Did you remove the float when you cleaned the carb. The float needle valve should be cleaned to make sure it has no varnish on it so it will slide up and down easily.

Also the fuel path from the banjo down through the carb housing should be cleaned of all varnish and gunk so you get a constant, even fuel flow. You should be able to hold the carb up to the light and see through the fuel path in the carb casing.

Also check the banjo pipe to make sure it is clean and free of obstructions. While you have the fuel line off, try the petcock in both Reserve and On position to verify you have good fuel flow from the petcock.

thanks Zippy! i will give those suggestion a shot, and i will let you know.

It is stock...I mentioned that in the original post at the top. I am going to do Zippy's check on the fuel line and petcock tonight. I ruled that out because my carb was flooding previously. There is no needle in the dellorto carb.
