Having completely rebuilt the engine and gearbox of RM64 since the Schleiz outing, all of the above modifications (and many others)! were put to the test when I entered RM64 in the VMCC Festival of 1000 Bikes at Mallory Park on the 13th July and again when I rode the bike in many sessions at Cadwell Park on the 24th of July. 2008.
From the moment MM and I started RM64 in the paddock at Mallory Park we knew we had made a significant leap forward with the bike’s development and so it was to prove for the rest of the day and at the subsequent meeting at Cadwell.
With the past clutch, head gasket and carburation problems now appearing to be behind us we spent the rest of our time at the 2 meetings just fueling up and adjusting gearing and suspension settings, the bike just got better and better.
Whilst good progress has been made this year. the RM64 restoration program is not complete as there are a number of items to be sorted including the development of a new exhaust/mega which will look like the original but meet the current noise limitations. A front mudguard and a strengthened rear hub are also in the pipeline.
In addition to the developments described above, work is slowly but surely continuing on my 2nd ‘high spec’ 250 cc Parilla engine.
This engine specification will include an Arrow connecting rod, light weight cam followers and G&S 6 mm dia stem valves, chain drive high cam and Nova racing clutch, all as currently fitted to RM64.
The higher spec elements will include a twin plug head, programmable electronic ignition, forged racing piston and may even include a Nikasil alloy barrel if the current owner of the barrel can be persuaded to part with it!
A new 6 speed gearbox has already been fitted into the crank cases and matched up to the Nova Racing clutch.
Once completed and tested, it should be interesting to see what level of performance can be achieved with the ‘high spec’ engine in comparison with the engine currently fitted into RM64. I hope back to back testing can be carried out, initially on the dyno, by the end of 2008 or early in 2009. All results from testing will be reported”.
