Just joined and I must say what a site! I hate to start off asking for help but here we go.. I recently inherited my Grandads '74 /6 that he bought brand new!! First off it has the funky 70's vetter windjammer II fairing on it huge windsheild i mean i'm 6 foot and on the center stand its almost as tall as me. I would like to take it off and put it back to stock. Was told that couldn't be done??? Secondly not a huge fan of spoke rims, any chance I could swap the spoked rims out for the aluminum snowflake wheels that come on later BMWS? Also the mufflers are shot on this thing wanting to " wake up" the sound a bit any suggestions? I have owned Harleys in the past so im accustomed to working on things Laughing, and not a noob when it comes to motorcycles. This bike sat for about 15 years due to illness and oil coming out of the rear vent on the differential. My grandad tore it apart to fix and got sick so it was put on the back burner. Any thoughts on how to fix that? I know i'm asking a lot but this bike meant something to him and it means A LOT to me so i'd like to get it road worthy and pay a little tribute to him. THANKS in advance!!!!!!

Welcome! Sounds like a labor

Welcome! Sounds like a labor of love, keeping something in the family.

I guess people are either fairing people or not. I happen to like my Luftmeister (Vetter knock-off) on my /7. It should be possible to get a shorter windscreen if that is an issue. As for removing it, it really shouldn't that much of an issue. There's an umbilical wire bundle that is spliced into the bike's harness, probably mostly in the headlight shell...all that will have to come out. Take plenty of pictures. The headlight might have been transferred to the fairing...I know it is on the Luftys. Turn signals might also have been transferred to the Vetter and those will need to be moved back. Vetter fairing instructions are here...this might help explain the installation so you can reverse it:

I don't think going to snowflake wheels is going to be easy...there will be clearance issues with the spokes and the brake caliper. You might be able to do that if you found a complete replacement front end for that time period. Personally, I prefer spokes.

There are replacement mufflers out there...EPCO, EMGO, Staintune(?), lots of others...I'm sure others will provide some suggestions.

How far apart is the final drive? It's possible that the only issue with oil coming out the breather that too much or the wrong gear oil was used. If it can be simply put back on to see if there really is a problem, that's what I'd do. If it's apart, I'd be inclined to have a professional reassemble it. Some shimming is required and heat is needed to get various bearings/seals in/out.

Thanks for the information.

Thanks for the information. The bike is together it's just not running at this time. Needs a new battery' an oil change, some fresh 93 octane and I bet she'd fire right up. I just didnt know if the oil leaking out of the vent was a common problem on these bikes or not.

As a general rule, they don't

As a general rule, they don't leak out the vent. Overfilling, wrong lubricant especially for the temps, can create a potential problem. First step is to get the right oil and amount and go from there.

Once you've gotten it running, etc., you'll need to consider an approach to maintenance to begin checking the important areas. Before running it, I'd strongly suggest that you check the valve clearances. With the wrong clearances, at a minimum it won't run well and you could be doing long term damage.

Oil coming out of the final

Oil coming out of the final drive vent cap indicates that there's too much oil in the final drive housing. Your grandfather probably didn't overfill the final drive; it has more likely "acquired" additional oil from the drive shaft due to a seal failure between the swingarm and the final drive.

Your wheel swap will be problematic because the '74 models had a smaller, 14mm axle. The '75 and later bikes had 17mm axles (and fork sliders, etc.), so a complete transplant would be necessary. Not sure if axle size is an issue for the rear wheel and final drive on '74 models, or not.

Welcome to the group!
