    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.

I'm going crazy. @ 4k rpm my 81 450t bogs. If I chop the throttle it will move right past into higher rpm and run well. If I just hammer the throttle it will move through the midrange no problem. Under normal riding conditions however it hits 4k and just sputters and farts.:mad:
I have removed the carbs, dipped 'em, blew them out and inspected every passage with a magnifying glass. Upon reinstall the bike runs like a top for about a week and then the problem reappears. I have checked the petcock and it's clean. Vacuum is tight and I can find no leaks. I also installed nice new fuel line. I have done this three times now thinking each time would be the last.
If anyone has any input that might be helpful it would be much appreciated as I am nearing the end of my rope.
Thanks in advance for any help.
 
Check the easy stuff first....

Plugged gas cap vent ? Pinched petcock vac line ? Leaky airbox ?
 
Sounds like the E10 Fuel is getting at your bike. I had issues last year with my wing. Had it apart many times and was going crazy. I found out about this treatment called Star Tron. mystarbrite.com/startron I've never been one to fall for the "snake Oil" additives but I have been using it since last June and the bikes have been running awesome. Boaters have been dealing with Ethanol Fuel Problems longer than us and have been getting great results with this treatment.
 
all checked. tight as a frogs backside and no kinks. i noticed some crusty junk in one of my drain plugs last time they were apart.
 
Appears to have the beginnings. I have been draining the tank and checking the filter and may or may not find 1-2 little flakes.

Thanks guys! I think i will clean and seafoam the tank and see if that helps.
 
Well, rather than pull carbs for the fourth time in a month or so I decided to look at wires. The blue/white R/R wire connector was slightly melted. I replaced it. I also suspected that the boot that kept all connections for the R/R and ignitor was getting sucked up into my intake. So, I pulled the boot back and out of the way let the wires breathe and guess what? Problem gone.:-k
