I thought I'd post progress over the next few weeks on the winter rebuild of the Group 4 race bike. Progress may be sporadic as I have two other projects on the go as well! But there is a definite deadline with the race bike so that will focus the mind!
Today I went down to the workshop at Replay Scooters - it was very handy to have use of the hydraulic lift in Chalky's workshop!
On the bench - mag housing removed
The old mag housing will be machined down to an absolute minimum for 2010 as engine will be upgraded to scoop cooling
mid transmission removal! Race engine cases are never together long enough to get dirty!
Gearbox and clutch out!
A hydraulic bench makes it soooooo easy to work on the scooter!
So...... progress is started for 2010 race season. Main upgrade planned is to convert the engine to scoop cooling. This will involve a new exhaust system (££££'s!) and machining down the mag housing to remove all but essential material. The cooling fans will be removed from the fan and a new - much larger cylinder head will dissipate heat away. Final piece of that jigsaw will be a cooling scoop underneath the barrel to help channel cool air over the head and barrel.
A few other modifications will me made inside the rear frame section aimed at helping with cooling......
More progress as it happens!
