Anyone found a good supply of 45C-50C thermal switches?

attempting to make up a simple coolant pump kit for my self and a friend, pump relay wiring all sorted, best switch i could find was a tridon TFS155, but at M16 it's a bit like shoving a pineapple up your nose. TFS242 is much better, but at 200€ i'd rather the pineapple.

Thanks, but most of those are not for coolant? if i stuck one on outside of the head, engine be melted by the time the outside got to 50C!

autospeed seems interesting, I'll blow the rest of friday reading it

you just place it on a blank plug temp is temp. as long as it a congruous it maters not if its water or air as long as its in contact with a decent conductor. and shielded from outside airfow etc
have a look at this pic

I could bond the cheap it to an aluminium m8 or m10 bolt, and with the bolt sticking out about half the hose diameter into the coolant flow, it would probably work perfectly fine, thanks Husa!

Thanks Husa, again very interesting info and Spencer's win with two crank engine really mysterious.

About carbon wheels, they really made second version CFRP wheels for Eddie, new dimension - 3.50x17 and this new version was a one piece molded spoke plate part, differs from previous combine of boomerang type spoke plates. Eddie used them two times, Hockenheim- second, Rijeka -third, but later stick to 3.87x16 magnesium, until the end of 1989. Maybe Gardner used Spencer's carbon front wheels as they was 3.75x16 at Donington and Anderstorp -third .

Has anyone tried to put a thin divider into the A-port as per the attached second picture? Let say out of 0,5 mm aluminium. I was thinking that it might help to decrease the short circuit of fresh mix into the exhaust by straightening and force more of the flow in the port angle direction? Could it make a performance difference? (More or less flow will also go straight at the section with the curved arrows).

HH did that on several replacement cylinders , but I dont know how much the guide has a positive influence on directional control Vs extra wall area and flow disturbance.

At the track Team Roberts would have outgunned HRC by 10:1 Even Kocinski said the same.
I cant remember what he said, but is was something like "look arround team roberts has 80 people HRC 10 and we are still getting smoked....
HRC was big of course about 400 people, but they also did a lot of other stuff, trails, MX and Superbike plus building the customer GP bikes etc.
Aprilia out of a total workforce of 450 i understand had about 62 people in the race program.
I have no idea what Yamaha had them but i know they have 67 engineers back in japan on the YZRm1 MotoGP team alone.
Plus 17 in italy and 55 at each GP.

Yes my point was despite the numbers at the track they were still working with what resources Yamaha saw fit to develop the base engines.

Got my Speeduino fuel injection CPU kit. Put it together and started to find my way around it and understand its methodology.

Attachment 338366

Interesting system. It has staged injection but instead of it being the small or large injector the Speeduino fires both together but varies the on time of them individually to suit.

I think that the injector strategy will be to stop the hesitation or step you would get starting the second injection. It will never be clean or controlled on the initial start.

As were Honda, Its hard to say how many people Yamaha had working on the bikes but id hazard a guess if you added up the total it was similar to Honda.
HRC certainly never had the track presence and staff at the track team Roberts did. Despite not using Ohlins who had their own technical support which Roberts also used.
The Yamaha staff at the track were mainly technical support.
I think you will also find Kanemoto developed his own bikes despite them being works Hondas as well.

another step. Machining the cylinder to take the injectors now also. Don't seem to get much workshop time these days.

That is very clever. I love it.

I can only go off what was in here
Attachements to follow.

I am not sure if i have the motocourse for that year or not do you have it?
Re the Spencer win it was with a two up 180 crank engine but he tested the twin crank as well i think both are in the spencer 5 part series buried, i only noticed it the second time i had read it.

okay not in there
It was 85 at the French GP. although it could have been a all fire within 90 degree big bang as well he said it sounded flat and powered out better much better and lead to the big bang, I asumed it was a two up whch was the Next step Honda took but the sound pitch goes down from the 90 degree even fire to the 180 two up to the big bang.

If i can get access to my PC tonight i will put a few bits together.
Horike designed the 85 250 He was a young engineer, and the only thing he'd done before that was to design the carbon-fibre wheel Spencer crashed on at Kyalami.
But looking at the source of my info for th eLawson wheels it was Cathcart lol
Anyway i see your carbon frame RS500 and raise you a early steel framed one

I cant imagine the CF one would have lasted long with the vibes of the NS500.
Honda had to keep beefing up the frames as it was.
From what i have read when Spencer went back to the three after the upside down failed to be any good the new NS500 engines would not fit the frames they had as Honda had changed the engine that year and ERv had to modify the old frames to fit the new engines.

Thanks for the reply, Wobbly. I was thinking that the divider should begin at the upper part of the transfer, be very thin, and end 1-2 mm from port window. It must be pushed/tweaked in there and fastened somehow, small welds or high temp paste/glue possibly. Well, I will keep it on my five year "to do list", with the risk it's just another "schnapps idee".
