    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. 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.

Fuel Delivery issues

Hi all! So my bike actually starts now, except it only starts after having some carb clean sprayed into cylinders. it dies after about 2 seconds, even on PRIme, and my float bowls are full. I already rebuilt the carbs properly, no clogged jets, yet it's like the bike isn't managing to pull fuel out of the float bowls into the cylinder. Is this a vacuum issue? Or is the faliure within the carbs?
 
Properly means you followed the tutorial?
Is the air box on?
 
i can't find a tutorial specific to my model of carb, but i followed the next closest one as closely as I could, while using the manual diagrams as a cross reference. The airbox is on correctly and i tested it for vacuum leak at the intake boots on both sides of the carb.
 
Sounds like the choke system isn't working. Did you make sure the choke pickup tube is open and the passage clear to the plungers? Also, the passage in the float bowls where the pickup tubes insert?
 
I never thought about checking the choke system at all! to check the system, can i remove the plungers and inspect them while adjusting the choke?
 
Check the rebuild tutorial linked in my signature and make sure you go through each element. Even if your carbs are different the basic function is the same.
 
Funny you mention that, because the tutorial I followed was ​the one from your bio!

Based on your comment about the choke plungers it seems you never removed them.
 
These are the plungers, right? They stay attached to the choke cables so i have to remove them to detach carb. They have veen removed a few times now, but i meant i never checked the passages at all.Snapchat-866295356.jpg
