Fist Time Rider - Issues with Idel and Throttle

brewsky · Post by **brewsky** » Thu Oct 29, 2009 4:36 am

I got mine from an ebay vendor here:

I believe Apex cycle has them also, and possibly Retrobikes.
The cable I got was in a 3 piece set and worked fine except the clutch cable was a little longer than my old one.
Make sure the throttle cable is for the Late model Dream with the slack adjuster in the middle of the cable.

brewsky - Thanks for the link. I actually went ahead and ordered the parts. Hopefully I'll have little issue putting these in once they come arrive. If so I'll be back on this thread!

I replaced the throttle cable and successfully freed up the throttle. Although it moves freely, it still doesn't really return. From the previous post I'm assuming this is due to the age of the bike, so I suppose there's nothing to worry about. After putting everything back together I cranked the bike and it idled great. I ran it a few times during the past few days and it has continued to run fine. I thought I had everything fixed until yesterday evening. After letting it run for a few moments the idle jumped back up. It has continued to do this the past few times I've cranked it up. From reading past post I've - ensured the cable is not caught an moves freely - loosened the screw holding the carburetor to finger tight. Any ideas? I would assume if I had connected the carburetor incorrectly than it wouldn't have run fine for the first 2 days. The only new aspect i have to note since putting the tank and carburetor back in is that after letting it sit over night I noticed gas leaking from the "over flow" hose on the bottom of the carburetor. I'm fairly certain this isn't related as I'm assuming I left the gas on. Since buying the back a month ago I've kept the gas off when not running. Additionally I made sure the gas was off last night and as of today there was no additional leakage. I'm open to all suggestions! Thanks in advance for the help!

Sounds like you have a couple of different issues.

First, the "finger tight" spec for carb mount nuts is a little overkill...they need to be snug enough to prevent air leaks...which can cause idle issues. You can spray some carb or brake cleaner (flammable type) on the joint while idling to check for leaks..if leaking the speed will increase.

Second, if the carb is overflowing form the tube, you have float or float valve issues..hole in float, improper adjustment, stuck valve, bad valve or seat etc.

Third, while the bike has a fast idle, check the throttle cable again at every location you can by moving it around. mine had a habit of catching the slack adjuster on the hole in the frame under the gas tank.

Fourth, the throttle is never going to return with the hard snap of other bikes which have an external return spring outside the carb.

Hi,

Are you sure that the grip is SLIGHTLY lubricated with a little oil or light grease. Never use to much grease, especially not heavy grease to lubricate the twist grip. No lubrication is even better.

Are you sure that the twist grip itself is mounted correctly ?
Does it have enough play to the left ?
is the throttle spring still strong ?, does it has the right length ?

If everything is ok, the throttle WILL snap.

brewsky - Originally I had the carb nut mount snug. I only loosened them after reading a post about it. I have since tightened them back and the problem still exist. Before purchasing the bike the carburetor had just been rebuilt so all parts should be good and in working order. If it is indeed something wrong with the carburetor, I'd have to chalk it up to improper assembly when i put it back together. I'll have to take a look at it again tonight. I'll also check the throttle cable. Thanks for the advice.

Jensen -

Are you sure that the grip is SLIGHTLY lubricated with a little oil or light grease? Originally it was caked with thick grease. I cleaned it up and applied a light lubricant.

Are you sure that the twist grip itself is mounted correctly ? As far as I can tell. It moves freely.

Does it have enough play to the left ? There seems to be plenty of play.

is the throttle spring still strong ?, does it has the right length ? Judging from the trouble I had putting the spring back in when replacing the cable I'd assume so.

I suppose my real confusion is why it would have run fine for a few days then jump back up to high idle. Thanks for the help!

Pwilke, If you think you have ruled out all of your carb maladies I would suggest you check your timing, particularly your advance unit. As far as tightening the carb to head bolts, all else being in good shape( O-rings, manifold flatness,etc.) very"much" more than finger tight "can" cause the slide to bind. I know this from my own experience. I would suggest removing carb, dismantling, thoroughly cleaning it(blow out all passages) and carefully reassembling it with the baseline adjustments given in the manual. Good luck.......PS, follow Eds recipe to the"T" for tuning..............D
