Modern Buddy

My 2006 Buddy was recently serviced and seemed to run well after. However recently every time I idle the scooter dies. It does start back up but obviously this is a problem. I have read about gas overfill and that may be the problem. I am mechanically disinclined and getting my scooter to dealer is a big challenge. If I did overfill, is there an easy fix? Oh, the scooter also backfires sporadically since this issue started. It has about 1500 miles and sits in the winter. Any help would be appreciated. My gas cap appears to be vented as there are 2 holes in it.

Try adjusting the idle. Your mechanic might have fiddled with it and turned it down a bit too much. You don't need to be mechanically inclined to do it - it's just the simple turning of a screw.

Here's the instructions:

A sporadic backfire could be an indication of a slightly lean condition.

Make sure the air filter is clean and check the air/fuel screw adjustment.

Then adjust the idle speed.

I'd recommend starting with the idle, simply because that's the easiest thing to do and the OP indicated that they are not mechanically inclined.

Also forgot to address the question about overfill - my guess is, that's not the issue. The stalls caused by that don't happen when you're just idling. Instead, they happen while you're actively moving, after you've ridden for a bit.

Check idle first If it persists, you might want to have the stator looked at.

Thanks for help. I just adjusted idle screw. After multiple quarter clockwise turns I am sorry to say I have no improvement for my problem. Any other suggestions regarding my sick Buddy? Cheers.

Put your idle screw back to where it was... check your air filter. If your air filter is fine, it could be the stator or CDI. If it is the CDI, you will have weak or no spark at all. If it is the stator, the output from the stator could be low. Not sure what the stock output is on the stator, should be in the manual. Other areas you could check would be the fuel supply line, filter, and petcock. Random backfires means your mix could be too lean.
