Thanks for the rotor info, I need to check what I have. I have the 18" rear from a NC30 if you're interested in a swap of some kind.
Interesting Yoshimura made cams for this bike.
I had considered going that route as I have the same wheel and swingarm. I found the exhaust I am using so saving those for another project. Interested to see how you do the exhaust. Looks like a very interesting project.
Not much new. The bike came with two lower cowls, both broken. Luckily the plastic is of the thermoplastic type so I was able to use a soldering iron to weld pieces together to make one cowl.
I took the opportunity to make it look a bit more molded to the Hindle exhaust by adding and shaping plastic.
The CB1000's should be the correct diameter although they won't fit the Comstar as is. The calipers shown also hit the spokes. I haven't revisited this setup but plan to.
I hear you regarding needing another project!
