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.

spotty

Vmax...why,yes i think i will
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

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!)
