Saw Aksland at Mallory at the '77 Match Races, incredible around Gerrards and everyone loved that black & orange colour scheme.

Alan North turned up at a Croft club meeting on this, it was brand new and he was just checking it out before a big meeting, couldn't believe my eyes when I was in the warm up area and suddenly found Alan and a new 750 standing next to me.

Anyone here know if the modern 'big block' & stroker race kits running in the liquid cooled RD/RZ twins are

functionally applicable to the big 4cyl TZ ?

 

A TZ 970 anyone?

Interesting, that last shot is of yet another un-modified A model being raced in `76..

 

Here is the showroom model that allowed for the F 750 race versions to be homologated ( not )..

No GL 750s produced for sale to public, sadly - Yamaha bottled out & built their (dud) version of a Commando instead..

 

& simply built hundreds of TZ racers to sell to the public, for homologation as F 750...

Noel Clegg on a Maxton framed TZ750 @ Silverstone 1977.

CleggNoelSilv19772014wm_zps054f8bb1.jpg

Photo Copyrighted to Graham Etheridge.

It spooked me a bit seeing this photo, I'll tell you a story about this bike.

 

I was marshaling at Cadwell the day that Mick Patrick was killed, Noel also fell in the accident and the bike carried on riderless for some distance before coming to rest just down from my marshals post which was the next one along from the accident but the bike had travelled around a quarter of mile up Park Straight on its own.

 

I ran to the fallen bike and somehow managed to to get it upright on my own (I was only 16 and built like a stick insect so it wasnt easy) meanwhile my fellow marshal was standing in shock, bearing in mind we had both just witnessed something of which the outcome was obvious to us even from the distance we were standing from the actual accident.

 

Having hauled the bike upright I felt myself becoming icy cold from the waist down, looking down at the bike and to my horror the entire front of tank had been torn way and fuel was pouring out, it was around lap 6 of a 20 lap race so it still had a fair amount on board and it just kept coming, I was soaked in fuel from the waist down and the fuel was still running out and sizzling on the hot exhaust header pipes I stood there frozen with fear!!

 

As calmy as I could I asked my fellow marshal to go back to the marshals post and I think my words were 'get a f******  fire extinguisher' when he arrived back I told him the situation I was in and asked him to take the pin out of the extinguisher and that I was going to let the bike go and take a jump back, and to be ready with the fire extinguisher pointing at my lower half, I let it go and ran like hell away from it, luckily it didnt ignite, geez that was one scary moment!!

 

That shot of the bike is the first I have seen since that day all those years ago.

Yes indeed Jackie was from near Belfast. A great rider in the late 70's. Unlike many from our shores was more known as a circuit racer rather than a road man. Sadly no longer with us.

 

I think I'm right in saying the bike in this picture is the machine that Tom Herron set the outright lap record of over 127mph at the North West 200 in 1978. (I'm sure my better informed friend TZ350H will keep us right!)

Many believe the GL750 shown at the Paris Show was a mock up and never actually ran.

Roger Marshall giving us a nice view of his Machin & Saunders TZ750 @ Mallory park RofY 1975.

Roger has recently been reunited with this bike on which he won his first British Championship in 1975, it has been fully restored by Peter Boast, this is the same bike as above, initially the bike ran under a joint sponsorship deal with Mal Carter hence the silver fairing, but later in the season it became soley backed by Machin & Saunders.

What about using the aero-devices & servos from a surplus ex-military A2A guided missile for active aero?

I remember that speed trap and that the figures were treated with much suspicion, i'm pretty sure a couple of TZ350's went through at 170mph that year!!

Me too,  I don't believe a bit of it, I reckon they added 20mph to the speeds, I think Steve Tonkin was one of the quickest 350s at something in the region of 171mph

That's correct Greg, and I think they got Eddie Roberts on his 350 at 170mph!! as you say the trap was widely believed to be a good 15 - 20mph out!!

To be fair, those I.o.M. trap speeds do pretty well correlate with the ~190mph speeds recorded at various other fast tracks back in the day..

Fastest TZ 350 Yam ( Yamsel )  through that trap ( 9th fastest) was Joey Dunlop @ 172.11mph,

 

Pat Hennen recorded 173.11mph on a  Suz RG 653 for 7th fastest.

 

Jack Findlay was 13th fastest @ 166.86 mph on his TZ 750..

Long time ago but the fastest 350 speed I ever remember seeing seen was at the 1980 NW 161 mph iirc, might have been Rutter or Williams, I think I wentthrough at 148 or 149, I think it may have been KH who recorded the fastest of the week just into the 180's

1=, T. Herron,   Yam TZ 350.....155.44 mph.

 

1=, P. Read,      Suz  RG 500....155.44 mph.

& a couple of comments in the mag relating to the fast Creg-ny-Baa to Brandish trap speeds recorded..

 

"This stretch remember, is a downhill straight which the fast boys take flat out."

 

& "Road dry. Moderate downhill wind."

 

I guess that in those circumstances, whatever your bike could possibly do, top-end wise, it would've done there..

And these 350's would have been D-spec at best in 1977!

As I said previously, a correctly modded and well set up stroked TZ (and you can bet Joey's was) will be quicker than a standard 350 :up:

 

Still not sure I believe those figures though, I wonder what system they used back in 77

 

D spec in 77 Barry / Bill  :wave:
