The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

THe GS650E is back together..................2 problems

1) After the bike sits awhile it will not start. If you prime it by blowing in the vent tubes it kick over, then runs fine.

The choke seems to have no effect.

Atilla says petcock, I say choke circuits.......

Now, since it runs fine otherwise it isn't the float bowls. It is only a starting problem from what I can tell.

HELP!

2) THe drain plug is stripped. I shot a helicoil in it, but it came out and I have a rubber plug in their now (one of the Jiffy lube specials that tightens in the hole). Any suggestions?
 
Re: THe GS650E is back together..................2 problems

Blowing into the float bowl vent tubes would pressurize the fuel, allowing it to flow through the choke circuit. Either the choke pickup tubes are blocked or there is a vacuum lock on the fuel flow. Starting turnover produces a low vacuum, so if the petcock diaphram is aged and becoming stiff, its possible the vacuum is not sufficient to open the petcock. I would disconnect the fuel outlet line from the petcock and put a spare piece of tubing on the petcock vacuum fitting. Drawing on the tube with about the same vacuum you would use to drink a coke through a straw should allow fuel to flow from the output fitting on the petcock if it is working properly.

If its a petcock vacuum problem, you should still be able to start the bike normally with the choke circuits operating if the petcock is set to prime when you try to start the engine.

If the petcock seems fine and it still will not start on prime setting either, I would suspect the fuel pick up tubes for the chokes. I had to clean out of a couple of mine a while back and used a bristle that I snipped from a stainless steel brush.

They make steel over-size self tapping ones in a variety of 'over-sizes', get the one that has a separate drain hole through the drain hole plug(like a small bolt tapped through a larger bolt), so once you tighten it into the stripped hole you don't have to remove it to drain oil again
 
Something that is almost always overlooked is the hole in the bowl that the choke tube goes into. You should be able to spray cleaner through this hole freely. If you put the cleaner straw into the hole and spray, it should come out of the the other end. If it doesn't, the choke tube has nothing to pull up, as gas can't get to the pick up tube.
 
Get this (and without intervention): The choke works now...........?!?!?!?!?!!?
