81'CM400 The green monster
« on: Jan 19, 2013, 17:50:51 »
This build started because my previous bike was stolen 3 weeks after it was finished. Since i was pissed I went the next day and bought the heap I bought parts off of for the first one. This was my first CM that was given to me by my uncle. The worst part of it is that it was stolen 30 minutes before I was headed out to RvsM.

i wanted to try to build as much as I could on this one. I started with the clip ons. I used a piece of .250 wall tubing and machined it to 33mm i.d. Then i too some 3/8" round bar and drilled and tapped them to m6x1.00. I used a 5/16" drill bit for the recess. I welded them to the larger tubing them cut through all three at the same time.  At first I thought I wanted a squared and skinny race style bike. So I played with some ideas. I actually started building an alloy fairing but changed my mind on the direction I wanted.

I was a sent a pic of a similar bike for inspiration by CafeMatty. When i seen it it changed my mind of what i wanted. So I started a new tank. The tank's shape was inspired by old Ducatis and Benellis. Then I built a new tail to go with the tank. The last pic is with all the mock up complete

Thanks guys, what really sucks about the red one is that's the bike that made me decide to start Retro Moto. Oh well, but because it was stolen the green monster was born. A full tank can take from 12 hrs to 30 hrs depending on the shape and finish. I can knock out a mockup piece in a couple of hours. Sometimes I will see the project from a different angle and see something else or get inspired by something and the vision changes.ost of my inspirations are usually not from other motorcycles. It can be a old piece of machinery, old hot rods, or random things I see while riding. But when it changes I just follow it. The only problem with building tanks is too many options,lol. Btw,my bike has been finished for some time now, you can see it on thebikeshed.cc or syb-magazine.com.
