    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.

What mods will I have to do to the pipe to get a Mac or Vans and Hines to work with this bike..
 
None to the pipe if it's the right pipe for that year/model. Put your bike in your sig for future reference. Is you bike an L model? You will need to rejet the carbs though.
 
83 850 G 4 into 1

83 850 G 4 into 1

It's a G.
So who do you know that makes a direct fit .. I have been looking at sites for months , nothing for 83 850 g .. I can get 750, 1000, and 1100.. If you know off something please share...

The closest I think is a Mac model #203-0601 but again not a direct fit....
 
1983 stock exhaust is the same as 1982 and should be physically the same dimensions as 1980 and 1981. V&H part number 12009 should fit without issues. The most I can think of that would cause a problem would be a slight modification to the rear support. I'd stay clear of the MAC's. Historically they're not as good quality as V&H.
 
Thank you .. Those are the model #'s I have along with Mac @203-0601.. I just did not know how much mod they would need.....
 
I've been looking into this recently myself, there seems to be a few differences of opinion regarding having to rejet etc, when I've been searching on here.
I have a Motad 4 into 1 fitted to my GS850G and according to the previous owner it has been for many years, I emailed Motad last night and got a reply first thing this morning.
This was there reply.

Hi Chris,

all of our systems are designed to run on standard jetting and air box,so no need for any adjustments.

Don't need to now about jetting .. Just want to no which 4 into 1 system will go onto my bike with the least or no fitment changes to the pipe it self .. In other words ease to install on the bike , will hangers match up , ground clearance, and that kind of fit issues. I know with pipes and pods I will need to jet until it runs good enough to make me happy.. I have pods and open exhaust now so jetting should be close..
 
I just bought a v&h from Z1Enterprises....reasonable price too!
