Hi all,

For some mad reason I bought an '85 K100RT on Craigslist a few months ago that had been tore down for "restoration" . I saw the words "cafe racer" in the CL headline and my imagination went into overdrive. So that is my plan and now I am seeing what bits I'll re-use and what I'll not. First plan is put the basics back together and get it running . It really "interesting" figuring out what bits go where  . I'll probably simplify the wiring - a lot - using a Motogadget unit and Acewell. I have already done this with my '82 airhead . 

I expect this to be a fun/frustrating learning exercise - I am by no means an expert! - and am looking forward to riding the Brick soon. Here's the progress so far . Oh, is my routing of the fuel pipe from the top of the fuel pressure regulator correct ie between TB #1 and TB#2 (third pic)?

Cheers everyone 

Welcome! I have to say, that's an interesting use of the existing exhaust system!

Hi Dai

I initially was thinking about the BSK collector + whatever exhaust but then I was reluctant to just sling the existing nice stainless stock exhaust. As the only thing that bothered me was mainly the length, I got out my hacksaw to look inside and I found the internal baffles are nicely split halfway. So then I just patched the old end on with a triangular bit to upsweep the end. I quite like the look and hope it sounds OK when I eventually get the beast started !

I just removed the air cleaner housing so here is a picture from the back showing what I guess is the right routing for the pipe. Can someone confirm this is correct ? I ask as this looks like the shortest route yet it does not fully reach the gas tank. 
 

The hose should come out on the front of the plenum chamber, and be connected to
the frontmost spigot on the tank.

Thanks Inge K. that is was I thought initially as well . However I can't see any room between TB1 and the radiator hose to squeeze a pipe through ...

The return hose is preshaped in both ends, the front end have the shortest part before
the ~90^o bend and is routed above the radiator hose.

Welcome kenrams, from one Michigander to another.

it looks like a good project

Hi SteveK1 

I'm looking forward to finding some decent MI backroads. Most around here are either potholed due to our brutal winters or pretty straight. If you have any MI road recommendations I'd love to hear them.   

Also hoping to try and get the bike to a track day this summer for some legal fast(ish) fun.
