Misc / Open / Engineering interest

For those interested in engineering thinking, design and application, this is a really really good watch

A very lucid walk through of race car design engineering, Honda powered  :)  with many gearbox and clutch component design shared with bikes.

Quite long, but very worthwhile viewing.

Misc / Open / CB 750 On't telly

Anyone see the eposide, last night, of Mike Brewer dream cars (or something like that) in which they trade their way upwards to give someone their dream car.

One of the vehicles bought and sold was a CB 750 partly built by a restoration expert "Andy" as he didn't want to complete for reason of, too much work.
Usual description, motor gone through, new tank and painted bits to go with it. The show "fall guy" for drama was most of a 4 into one system, without silencer.
Que explanation by Mike as, rare as hen's teeth, impossible to buy, no replacement made of the 4 pipe system needed to complete. He'll get on the blower to "World wide" contact network to see if he could locate such unicorn items  :)
Cut to later round up, he'd located a chap called David Silver no less !! and found none available to supply for another 5 months  :-\ but good news, customer had returned a set he didn't need  ;D that could be purchased for a reduced £900 yay, pipes arrived, Elvis fitted them,  set final drama of the " will it start, won't it start" shenanigans just for the punters you'll understand. 
On the button, first time........but looks like a lot of throttle Elvis is using to keep it going there :o

Sold via bidding to happy new customer.

Cut to real target, Caterham super 7 for happy ending. Aaaaaah.

Oh, and the alignment of #4 downpipe looked, ahem, not quite matching other pipes, that's just from a quick look in telly land editing.  Probably why they were returned to DS if that's definitely there.

Reg no PMF 115R and thought they said a 1972 model, painted fork ears too, likely a bitsa. Thought it had K2 top yoke and clocks, possibly.

For those interested in deeper examination of mechanical parts within some engines

Warning, for the impatient it may not be for you  :) slow delivery but a very lucid look at this element of engineering from Brian Garvey.

Unsure if posted already as title with someone making available new part to substitute for damaged/ no longer available items.

Looks interesting,  haven't watched it through yet.

I love this era superbike racing, pretty good looking modern build

Possibly of interest to someone no connection to me, but came up on associated interests while listening to music.

It's a fairly short article, but does illustrate just how much of a challenge it is to match combustion fuels in numbers that attempt to operate in the same performance field

In an ideal situation these developments and consideration would have happened 20~30 years ago, in which case decisions wouldn't be in such a forced state now and with more evolved solutions to accomplish differences in end user profile.

I've put the race link here as I believe it offers more open comparison of raw capabilities in direct numbers than alot of the consumer facing fluff that's put out currently.

Looking at Ken's thread on disc brake material, I was doing a little digging in such topic and came across this on the  .net Honda forum  :o :o :o ;D

It's about the thirteenth post in the thread, quite an adventure by all accounts  :)

As title, thought this was a lovely looking bike from 750 motor start point.

As title,  history of Yoshimura that I've not seen before

Multiple pages,  near bottom of page are two arrow for going through the site, not that obvious initially. Quite a bit to read.


Tricks & Tips / One off exhaust mock up

Discussion on here some time ago about building a bespoke exhaust system,  found this while wandering the www and thought it was quite an elegant low-risk cost of prototyping something individual.

From the years of our bikes (well loosely) it gets there after a bit  :)
