    Have you considered having the foam in the seat cut down and then get it recovered. That way you might achieve the room you need without compromising your suspension travel.

    Update on bike:
    Bike is being torn apart so the frame can get powder coated. I have started making sheet metal pieces as I take things apart (seat pan and air box block off) and making a list of bad parts and new parts needed, when I stumbled across something I cant find a simple solution to. This is where I need some help. I have a breather line that goes to my airbox. I believe its a crank case breather (at least its what I have seen from here). I can not find a page that shows how to modify this to get rid of the breather line. can soemone help?!?!? I think I need a reed breather valve. I have a 1980 r100rt. All help would be greatly appreciated

    Your second photo shows the oil pressure switch. Replace it with the VW one, then plug in the two prong plug, I don't see this wire in the photo. . This most likley the source of any oil on that part of the motor.
    You have the clean air system on this bike. it runs from the air box to just in front of the exhust nut on the underside of the head. This can be removed as it does not seem to do anything. It was to add clean air into the head to help the unburned gasses burn. I found that a 6mm allen can be used to fill the hole after tapping this port. . An auto parts store block-out plug will fit the airbox holes.

    Looking at your last picture, with the oil and grime everywhere, I was thinking the rear main seal might be the issue!
    The good thing about that, is you can change the neutral switch out easily, once the gearbox is out to get to the rms.
    :eek1 :evil

    However, before tackling that, the left front pushrod seal looks to be leaking and I'd ensure oil wasn't from the oil pressure switch near your left toe. It looks dirty, but not wet like the pushrod seal is. It's probably just tracking back from the seal.

    btw, the last pic is upside down.
