    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.

carb synchronizing

I know I've seen this method before but I've heard people say it wont' work.

Well, I just wanted to share that I managed to take my bike from a not running state, to a running and feeling great state with the homemade carb synchronizer.

I made a manifold out of screw together pipe fittings (2 T's, and 2 elbows). Hooked 4 pieces of 5/16th ID line to the manifold and then to the vacuum ports on the carbs. To connect to teh carbs, I took some 5mm bolts, and drilled a hole through them. I hose clamped the hose to teh bolts and threaded them in. I filled the thing with 80W 90 gear oil a couple of feet high.

At first the cylinders were so out of balance that i could only start it for a split second before it would try to suck all the fluid up one hose. I would then adjust that one cylinder down a little and restart it. After repeating that process a few times, the cylinders were all close enough that the fluid would remain in all 4 hoses at different heights. from there I fine tuned them all to within about 1 inch of each other at 3000 rpms.

going through the different rpm ranges, the levels fluctuate a bit but for most of the range stay pretty well balanced.

The bike seems to run great now.
 
Hey, if it works, it works. I dig the black engine and dark pipes, very understated. You going for a camo look (fender and side covers) or is that primer?
 
thats teh color, i saw someone else on here that did his bike like this and i love the way it looked so i figured I'd try it out.

heres a full shot
