1. I would check the needle valve under the float arm. Make sure the arm is not bent too low never turning off the flow of gas when the carb bowl is full. There are photos on the web showing what it should look like when proper. 2. Make sure the needle valve is on the correct side of the float arm. 3. Check to see if the needle valve point is damaged. 4. Check to see if the needle valve seat is damaged or has rust etc in it. Just some ideas to check.

Having the motor rotor shaft end wear out in 1,000 miles ( how many starts?) is not normal.Even with no grease they should last for years with "normal" start times. Lubing the end caps will help but only to a point. If you still have all the receipts,I would contact the seller and see if there is a warranty or if they are aware of this short life problem? You have rights as a consumer you can exercise.
I would also check out your starting voltage. Make sure the replacement starter motor is the correct voltage. a 6 volt starter in a 12 volt system will have a very short life. Also make sure the starter "Bendex" is not binding on the flywheel causing undo sideway force on the shaft.
The new Chinese cone air cleaner for the Dellorto showed up today. The engine has a deeper growl and engine response is much better. Top speed is still 35 mph. At my altitude and original exhaust, I'm probably at my max speed. The bike will not climb a steep hill, the clutch just does not have the bite due to the lowering RPM.
I drove down to my mail box and let the bike idle while I got the mail. When I pulled away from the mail box the bike acted like the plug was fouled a little. It stumbled for the first 100 feet or so and then it will catch and take off. Is this a jet problem or is something else going on. The engine had been run for about four minutes when this happened. The spark plug has a light coating of black carbon on the ceramic rather than a brown coating. I'm running a 68 jet (Delerto). Straight fuel and the bikes automatic oilier. Any ideas?
After reading many post from all over the web, I'm torn as to change out my exhaust system. The fellow who posted the Modification of the original muffler vid has since recanted. He says it does not help performance and makes the bike really loud. I've also seen post where some of the guys who installed the "side bleed" type tuned exhaust have also removed them for poor low end performance and excessive noise. I'm on the fence as to do anything to my bike's exhaust?
I'll try again. Front view. Walmart basket ( 3 bucks) to hold my mail.
cylinder cooling fins shaved to fit between foot pegs.1/4" had to be removed on each side. Treatland Delerto adapter. Delorto SHA 15.15 carb Head on view-Head light bulb is replaceable Rear view Speed-o-meter with LED back light Tail light is also LED. All battery powerr goes to headlight which is good. It does not go bright/dim via engine speed.
