Misc / Open / 1974 Belgian GP footage« on: December 14, 2021, 03:42:56 PM »
Sadly no sound, but some nice film of miscellaneous parts of the Belgian GP.
https://youtu.be/PjeCGQtQ9Cc Looks that much of it could be shot on Kodachrome as the colours are typical (also stable in archive) with a short bit possibly another film type as fidelity isn't a match. 18

400 four pipes that are tatty and have non std rear, but could be of interest in some of the component parts. The collector looks like it's still inside the hash rear pipe, not cheap but could be something to replace other poor bits of a system. Also look through the other items listed as theres a fair bit of stuff there for honda that some maybe searching for. 19

Anorak's Corner / Life of Hi........................Vo« on: March 15, 2021, 01:14:12 PM »
Topic as title, often comes into focus in different threads with detail embedded but a little difficult to find.
The primary drive chain of smaller Honda 4 cylinder engines appears to be one of the most frequently worn components, even if the other parts show very good lifing for the mileage they've completed. It may not show a good condition with even the most diligent of servicing, and so to consider some of the influences that could bring this about. It's a Morse type chain design, developed into "Hi-Vo" as a defined product by Borg Warner transmission company. A combination that's split between very clever design and mechanical performance but opposed by very simple materials (could be considered crude) and construction that gives some fairly unique properties. Essentially could be considered as a linear gear drive with soft engagement to rotating gear pairs, it can mask mechanical condition exceptionally well from new to old tolerances. High torque capacity but with the trade off being it's relatively heavy for given size that has an effect of centrifuge at high rotation speeds. This aspect of the design seems to be one of the contolling parameters in Honda using two small diameter gears, then changing ratio onwards to gearbox by using differential clutch drive gears to complete the primary route. Still, it's capability has to be rotating at 10,000rpm crank speed and keep together with that attendant centrifugal force acting on it. This does in reality provide the "tensioning" with this type of drive, and why they are usually used without such devices. 23

Peter Williams 1939 ~2020

Really good quality filming of 1960s motorcycle scrambling, with some terrible engine noise dubbing

Came across this item, says it was developed in consultation with the kettle club. Is anyone thinking what I'm thinking? There must be enough interest of both 750 and 500 owners, isn't there? Looks a very convincing reproduction and for general use that stainless construction would sway it for many. 28

For those that like this era of road racing this is a really good short film, principally Agostini but so many other characters also. Good footage of Phil Read on MV some great sound track too on surely one of the best looking bikes on the planet. 29
Anorak's Corner / Carb setting for pod filters etc« on: May 10, 2019, 05:23:52 PM »
Found in an old magazine, it's carried out on different engine but clearly shows what happens when removing the std airbox and then to compensate via rejetting to run correctly.
[ Guests cannot view attachments ] Clearly shows with test data why it is difficult to sort out just by changing existing jets when it's really a response curve mismatch that is the root cause. 30
CB350/400 / Neat 400 based racer.« on: March 25, 2019, 04:16:59 PM »
Thought this was a good looking race adaption of 400, more practical than stylised with very neat details.
