N15CS oil tank mounting

Ludwig,

do you avoid denting and deforming the rear mudguard entirely? That's very surprising, but great news if it works.

I have never seen used samples of the late G80CS style seat (pan). It's supposedly a variation of the seat pan used up to 1966. Maybe the lack of offerings is because they crack and get tossed?
I remember seeing an ad from an aussie, offering new seat pans for the G80CS.
Can you please show us how your reinforced seat pan looks like? Or make a sketc?

As I said, the first thing to break was the rear loop, forcing the fender down and caused the bending and cracking of the seat pan.
I replaced the fender with a stainless one, but can't recall if the original was cracked around the fixing point ( don't think so..)
This is how the seat pan looks now with the repair and reinforcement points:

The rusted rear section was cut out and replaced with stronger metal.
The curved ( taped) crossbar is to help against sliding back.
I mold my own foam.
The lip was also strengthened
The plate is galvanized to prevent rusting.
(cable is spare clutch cable)

Reinforcement of the rear loop:


The rear fixing point is no longer a bolt but quick release, because I use the space below the seat for storage.
tools, etc..



It's been like that for 30 years or so, and it is doing fine.
I use the bike for long distance traveling, and virtually EVERY part of the bike is modified in function of it.

I am new to this site but I have a G15cs/109919 with the fender bridges your asking about. They were used on the early bikes with the ribbed fenders and two straight braces. The two bridges looks like your drawing but has a threaded spacer welded to the outside that is 7/8" dia X 5/16" thick. They mount under the fender at the shock mount and and at the rear. My bike was completely taken apart in the late 1960's with 7200 miles still has a set of Pirelle Importe D'italie tires way before date codes. Hope this helpes.
