Hi all. Ive been asked to build a bike for a guy whose into moto GP. This bike was raced by a few teams, most notably by Kenny Roberts who won the world championships 3 years in a row.
There will be 4 sets of fairings depicting a different bike for various riders and teams.
Heres a few pics of the beginnings...

Bit more detail on the engine. Added the fuel lines.
This is what Im attempting to do with the kit:
The donor Tamiya YZR500 (OW48) kit and will convert it to the 1979 YZR500 (OW45) factory version, as well as the 1980 TZ500 Factory production bike leased to privateers that racing season.

I know you like a bike or two. I like the engine work on these machines.
Ive aldo started a 1/12 Mp4/4 Mclaren by Meng, but its been on hold while Ive been working on some models for other people. Will but a wip up later for that.
I bought myself a set of high end drill bits from 0.3 to 3mm in 0.1mm increments, and a good pin vise.
It seems to be essential for adding the cables and lines. Wish I had one sooner.

One more post for tonight...
Got the spark plugs in - I drilled out the plugs to fit a smaller cable. The Tamiya kits always have a too-thick cable for their engines I think.
Also mounted the engine into the frame. Its a lot easier to handle now and its been detailed up a bit with some pe bolts and painting.
The plug leads will go in tomorrow after the glue has fully set.
Looking good so far.

Started on some decals. Lots of curves, so a real pain to get them to contour. I use Tamiya's Mark Soft Strong.
The red on the back cowl is also too short, so I'll have to match the colour to extend it to the edges.
Overall looking pretty good though. A nice clean colour scheme for

Jonny Cecotto's fairing is mostly done. Moving onto Kenny Roberts, 3 times in a row world champ 78 - 80
Kenny Roberts
Heres a sample of spot models decals compared to the old Tamiya decals that came with the kit. [Tamiya at the bottom.]
Spot models need to get a far better resolution with printing. They really are quite inferiour. So Im using the Tamiya ones for this fairing.
Reference pic of the bike to copy, different to Tamiya's reference. They chopped and changed stickers a lot - even the instructions say a 'Canon sticker was sometimes seen on the bike.'

The instructions tell you at what stages to make the mandatory noises.
