Hi everyone! I've been working on a bike for a while and decided I'd start a thread to get feedback and to get help when I get stuck.

Here's a picture of the bike when I bought it. The engine ran OK, but the bike was misssing som parts like som bolts, and one of the engine mounts. I descided to take it apart and make sure everything was in order.

All the small parts removed:

This is how the bike looks now:

I'll explain some of the work and choices I've made in the following posts

I have no previous experience with metalwork, so behind every part is a lot of Googling and hours of Youtubewatching.
In the next picture I've made some kind of buck to bend the rear seat around:

Here I've been trying some TIG welding. extremely easy to burn a hole in the thin plates:

Here the seat and tank is painted, rat-style. The tank is a cheap, dented one from a Honda CX500. I also found a how to make a seat on Youtube, so I borrowed my wifes sewing machine and followed it as close as possible:

Wanted wider rear wheels and also wanted to get rid of the cast wheels. So I got hold of a 1977-9 gs750 hub. This hub is for both disc brakes and spokes. Ordered a 4.25x18 aluminum rim for it and powdercoated spokes and hub. The rim was powdercoated by the supplier.

I have a friend with a cnc-router, so I decided to make my own rear sets. Excited to see how that goes:

Intriguing. I'm in.

 

[canyoncarver]

Cool!

nice, i had the 1100 version a long time ago, it got a 70 endurance racer fairing and a genuine CB1100R kevlar seat, hideously uncomfortable but looked great and went like stink (topped 250kmh out on the highway)

i was amused to see the pic with "small parts removed" with the headlight taken off, not what i'd ever have described as a small part.....

keep up the good work

 

[Hurco550]

I like it! Nice work so far

Wait, what?!? First time making all this stuff and it looks that good? Kudos my man, looking great! (And I hear you on the Youtube thing - I'd be sunk without it!)

 

[hooligan998]

In. Inspiring work.

 

[CarbsAndCylinders]

Looks great!

Thanks for all the friendly replies! I will keep you updated

Got som time with the bike today. Did a test of the rearsets on the brake side. When i have the final measurements for both sides I will make some more parts on my friends cnc-router.
The arms that hold the linkage will be about an inch shorter and much slimmer in the final version.

Today I got to finish one of the parts that I've really been looking forward to see finished. The Motogadget MIni embedded in the headlight. The result is not perfectly symmetrical, but close enaugh

Very cool. Nice work.

Rearsets testing. Needs better finish and some adjustments

Should I powdercoat the rearsets black or leave them as they are?

Let them stand out, there is artistry in them
