I thought it may be a good idea to get this ol' write up out of the archives and post it for your thoughts. This was all written before the bike actually hit the track. I will go through again and update anything in italic print.

1. The Bike When we bought it.

This is a shot when we first purchased the bike in may 2004. Bare chassis was there along with the majority of bits and pieces to finish the project. However, it was lacking small bits that often tally up and become quite expensive in their own right. Also, it was only really a bare chassis. There was no substructure beneath the rear fairing to support it, no tank mounts etc... The engine is there, but hollow, Turbo system was there but not suitable. Get The Idea?

2. Bike at our workshop.

A few months after the purchase we finally got around to organising our new workshop making benches etc. Here the bodywork is removed so i could evaluate what needed to be done, made and so forth. Turns out it was actually quite a bit. So here is where the real journey began. I had a lathe, but couldnt use it. Same goes with the milling machine. Had a Tig, but couldnt use it. Basically, i knew i had the equipment to work on the bike, but no idea on how to use any of it. The main focus at this point was to work on the body for the bike. We did have a very basic plug, but this would require alot of work to complete, as will be discussed below.

3. Working on the plug.

As you may have noticed in section 1. The bodywork on the bike was lacking alot. As a matter of fact, it was atrocious. The main shape was there, but there was no detail work, holes all over it and it was extremely lumpy. So another learning curve began. The magic of Fibreglass and body filler. So we put some bits of glass here, filled some gaps there and so forth for around 600 hours before we had the plug to a satisfactory state. Add to that prepping and spraying in high fill, polishing, waxing and spraying a release agent before even being remotley near making a mold. With a bit of gelcoat here and some fibreglass there and another 20 hours, we finally had a mold, but no body to use on the bike! Another couple of hours and some late night work gave us our final body. Satisfying considering the hours myself and dad put into it. All up, probably around 700 man hours involved in making the rear fairing, and it was still far from perfect.

4. Dummy Build.

Above the bike begins to take shape. After spending many hours at Shearer Brothers Race Cars learning how to work with steel from the guru, i had learnt how to tig weld reasonably well. With Mark also helping the project by supplying the chrome moly stock i required to finish the fab on the chassis, plenty of time and energy was saved.

5. Beginning Final Assembly.

A fair while after the dummy build, i was ready to commence final assembly. Because my modified bike was deciding to be a ИИИИИ and breaking constantly, i lacked time to work on the bike. However, myself and crewman alex rocked up one friday morning and said, we are gonna finish the raw fab, have this in paint and rolling before we go home. I thought we stood no chance, but we were both willing to put in the hard yards and the photo above was taken at 4 am saturday morning, after starting on it at 9 am friday. While Alex was cutting brackets, bending tube and painting the frame, i was at the other end of the shop putting the bottom end together. 9 am saturday morning after 3 hours sleep, the bottom end went into the frame.

6. Wheelie Bars...

At this point, i decided it would probably be a good time to start working on the wheeliebars. After spending a few hours toying with different ideas in CAD, the length and construction of the bars was settled. The main bars would be 1 inch, .058" wall chrome moly, with vertical kicked back connectors made from 3/4 inch, .065" wall chrome moly. Cross bracing is 25x3mm aluminium and the axle is 5/8 .065" moly with threaded still inserts at either end. After 10,000 coffees and 35,000 smokes at SBRC one afternoon, the design was finalised, the tube was cut and i was sent to our shop to begin the fab work. After a week of work the bars were finally completed resulting in the images shown above. Overall, the wheeliebars are 90 inches long.

7. Paintwork.

After many deliberations on design and colour schemes for the bike, myself and co-crew chief James had a flash. Sitting in the shop trying to come up with a concept, we both looked at dad's classic 900 kawa in the corner of the shop and thought "thats the s$#t...". So after some playing in photoshop and some printed photo's, my man chucky got the bodywork. After 3 months of toying fiddling and racing his own bike, i got the call. Went down and was amazed at the job. Got back to the workshop, sat it in place and took the photo. As you can also tell, the top end is one the engine. Managed to do that on another friday night barnstormer.

8. Keep forgetting to bring the camera.
Since the last shot, i have started wiring the bike, as well as creating the fuel system and air system. With any luck, we should be on track by the start/midpoint of next month pending on my financial and academic situation.
