My first airhead project. HELP!

Hello all.

New member and new project here. This is a great site for a ton of info. I'd like to pick yr brain and gain from everyone's years of airhead experience

Here is the bike I just picked up. It's a 1984 r80 that has a bunch of /5 parts on it. Most likely due to a crash or wanting the vintage look. Which is good for me cause now I don't feel bad about chopping up a cherry unmolested airhead. All work was done by a bmw specialist and came w a ton of receipts.

http://flic.kr/p/jqJg4b

I dig the headlight/speedo cluster, magura bars, spoked wheels and fuel tank. Everything else. Meh. Not so much. They will change.

I am looking to make this a better street bike only. No off-road.

Suspension

Front:
- I'd like to replace the front forks with inverted/usd street bike ones. Ie gsxr or zx12r.. I know this will require new triples and other height issues.

Rear:
-I'm considering yss or ohlins

Brakes

-I'd like to put a dual disc on the front along w better calipers
-I can live w the rear drum brake.

Frame
-would reinforcing make a big difference?
-I'm tempted to fabricate a new rear frame. Would there be any benefits to moving the shock mounting points?

Sidecar use
Cana sidecar rig be attached to this model? I know that would effect everything if I plan on going that way.


Any help, shortcuts, links would be a great help.

Tom

It really seems to be more /5 than 1984. The headlight and all the lighting on the bike is /5. So I would guess the wiring is the older bike. The electric system would be the older bike but the Alternator would be the up dated 1984, more power.

It's a Frankenbeemer for sure. You're likely to not know what year anything is until you start to work on it.

I would check the numbers on both engine and frame. Cant imagine why he would change the alternator and starter covers and go back to the old air cleaner. But stranger things have happened. Same goes for the kick start.

Links from your link are not "recognized" by this website.... for whatever reason, you have to use one of a handful of paid web-hosting photo sites....

Flickr is nice too, the share menu allows you to select for HTML option and produces the correct code to copy/paste into the text box so the pictures are imbedded into the text

Your best bet for the front end is getting a complete front end, axle to controls, from a gsxr 600/750. They are the longest of the gsxr forks (I think, >2006 is the longest but not totally sure; there a few versions of a fork conversion table floating around that lists the dimensions of popular forks). They are readily available on ebay and at motorcycle junkyards for pretty reasonable prices (~$1200 for basically brand new to $400 for older stuff). They are fully adjustable. The shocks and brakes are damn good for all model years. With three spacers (that you'd have to make or pay someone to make), a two into one throttle cable, and some disks from a bandit, it is pretty much a bolt in affair. If you don't want clipons or would like the steering angle range of OEM, you might have to make/buy upper and/or lower braces.
