Sandwitch plate adapter for 5VY R1 - where from?
Hi, does anyone know where I could get a sandwitch plate adapter to fit between the oil filter and the block on a Yamaha R1 5VY? Apparently the usual
Mocal, etc. adapters are too large to fit the block.
We want to run an oil cooler and are looking for a suitable sandwitch plate (The oil filter thread is 20mm x 1,5), preferably with a built in
thermostat.
Thanks for any tips!

We use the Mocal one on our 5VY engine.
You are better off getting a take of plate rather than a sandwich plate.
Take off the oil/water cooler, get one of the threaded inserts that is used to hold the oil filter on and use that to hold the take of plate on the
old oil cooler location.
I think we may have had to machine or grind off a tiny part of the take off plate to get it to fit.
Think automotive do all the parts you'd need. So do Merlin and demon tweekes.
Sandwich Plate
Cover Plate
Yamaha Part -
90401-20145-00 BOLT, UNION
I'd advise on using JIC connectors not barbed ones when you plumb this in due to the high pressures involved.
You'll have to cut this union down slightly as the threat is too long.
Works really nicely.

Thanks ko_racer4
Just so that I understand:
You leave the oil filter as it is, on the block.
You take off the oil/water cooler and fit the Mocal sandwich plate PLUS the cover plate?
Then you run the oil lines from the sandwich plate to the oil cooler?
Sorry if I don't quite get it...
Thanks!

Don't suppose you can send me the details on the breather mods etc that you have done to your engine.
Another thing we have seen while racing these engine is that you need to use CR10EK rather than CR9EK's especially if you don't have a
good cold air source for the intake

Why do you use the different spark plugs?
We have a Pipercross airbox with a feed from the nose (cold air). Are we OK with the CR9EK then?
Thanks!

Would be good if you could put together a comprehensive list of the required parts for the oil cooler when you do it, maybe get some pictures.
We've two engines which we will probably do shortly, with a list of bits it would make it a lot easier, only variable will be the length of
hoses to get it to the nose cone.
What size cooler are people using?
What do you do with the water hoses which would have connected to the original cooler? Join together or just block off?

We have moved to the colder plugs as we have detonated the top end of 4 engines now. It burns a hole between two of the cylinders. Mainly on hot
days.
A few engine tuners recommended this after seeing the damage as one of the many things we did to counteract this damage.
The Yamaha race kit also specs 10 plugs (colder) albeit very expensive ones 
I'd say use the 10's, especially if on track, we've found no negative reason for using colder plugs, starting and idling just as
easy.

Interesting find? Here, selling for $150 surely
someone can make these for us for less? Lump of ali and 20 mins on the lathe / milling machine.

Yes, I have seen that, too, but can't exactly justify the price...
The one thing I don't understand is the difference between a sandwich plate and a takeoff plate. They would both fit on the oil filter thread
and have the possibility to fit the oil filter on the other side, or run a remote oil filter using a cap of some sort.
What am I missing?

ko_racer, can you please post a picture of your take off plate on the engine? That would help me so much better than descriptions.
Thanks!

I can't really get a photo as it's positioned right out of the way in my car.
The sandwich plate and is part of the the take off plate.
It's a Sandwich plate if you fit it between the engine and filter and a Take off plate if you use the cover and bolt it on the old oil cooler
location.
It fits just like the one in the link in the post above. Just not $150.
From memory we had to remove a little metal to make it fit, but all very simple.
We didn't use it on the filter as a sandwich plate due to space restrictions and tidyness. Not sure the castings on the block would let it fit
their either.

This
http://www.merlinmotorsport.co.uk/p13398/BILLET-SANDWICH-
PLATE-1/2BSP/product_info.html is the one I have fitted as a sandwich plate. There is not enough backspace to allow it to go over the M20 filter
adapter thread flange and sit flat. I reduced the adapter flange size so it would fit.
You have to fit the plate at a angle that makes it foul on the water line coming from under the prop adapter area. I just removed the tube, cut down
and added a flexible pipe to make it easier.
See if I can sort some pics later.

P.S. Anyone running a clutch oil line on a R1?

We have received our take-off plate and it fits with the slight cutting / filing of the M20 union that will hold it in place.
The take-off plate itself fits nicely in place of the oil cooler.
I think this is what we will go for!
Thanks ko_racer!
(Please note the engine is the damaged one and the take-offf plate is only trial fitted on it...)

Do you use the original oil cooler fixing/bolt to hold the sandwich plate and cover in place?

Just done this, in place of the oil cooler, a couple of tips for anyone who does this.
1: if you have trouble getting hold of the correct union (threaded on both ends) then get the original long bolt that held the cooler on, cut off the
threaded end, now use some strong thread lock, and half insert the threaded section onto the standard union you get with the sandwich plate, you know
have a union to fit the sandwich plate.
2: this is the bit which almost caused me a major heart attack, as my oil pressure gauge would not show pressure!
The oil cooler oil flow is the opposite to the oil filter, as with the oil filter the oil comes from around the side through the filter then through
the centre union and in to the engine.
Now with the cooler it's the opposite the oil comes through the centre then goes back through the side into the engine.
And don't try and fit a second oil filter here instead of a cover plate, as the oil won't flow backwards through the filter, or not at any
speed anyway.
My only worry here is I don't know where the oil goes in the engine once it's gone back in through where the cooler was, does anyone know
if it's connected to the oil galleries?, or does it just drain back to the sump?
Just I've got my accusump connected here, and would be a bit pointless if it just drained back into the sump?
