Got the problem fixed. 1) Replace the choke plunger assembly: cost $11.14 plus shipping at http://www.jetsrus.com/individual_parts/007_752_su.html The company is JetsRUs Part Number: Starter Plunger Assembly VM16/210A 007-752 Bear in mind that the above part number is for the "short barrel plunger" these are hard to find and this is a really good price. If you have the "Long barrel plunger" these are easy to find. Look at yours real closely and then look at the pictures of the long and short barrel plungers on the internet you can tell which one you have that way. I say it like this because after doing the research myself, the parts people I talked to did not know which one would fit my carb, so I just looked at the pictures very carefully and you can see the difference between the two. Note: Air leaks thru an old choke assy. When you get the new one you will see how much tighter the plunger fits the opening it goes into. 2) Make sure a good plug is covering the little brass tube that is under and just to the right of the choke knob. Go to any auto parts store and get the vacuum line junction plugs, you need the 1/8" size, this fits tightly. Don't trust the original one if you still have it on the bike because it could be old and dried out letting air by, even though it looks like it is still intact. 3) This has to do with the oil pump injection system. If your oil pump injection system is connected and working fine disregard this step - just make sure the oil line from the oil pump to the carb is not cracked or worn or dried out or leaking oil where the oil line connects to the carb. If you have the oil pump disconnected and are mixing the oil and gas in the tank, make sure to put one of those vacuum line junction plugs where the oil line is supposed to connect to the carb. Don't leave the oil hose connected to the carb, you are only sucking in air there. You can buy a package of about six of these plugs for around $2.00 This solved my problem entirely. I was getting a bad case of the revs not dropping when I let off the gas, this was really annoying as you know when you are shifting gears. The carb idles perfectly and the revs drop when I let off the throttle. Plus no more run-away idle. One more crazy or odd note. Before the fix, when I started the bike and the engine was warmed up and the choke knob returned to the "in" position for riding. If I ever, ever, ever soooo slightly pulled the choke knob back out, the revs would race to 5000 rpm, no kidding, I pretty much thought something was up with the choke.at that point. Mine was the original choke from 1979 and it was pretty sloppy inside. Hope this works, Steve 818 270 5957 I live in Sylmar California
