Works X75R motor.

[BoostedRooster712]

I had the pleasure recently of going over this engine for a prospective purchaser.

Deal didn't go through as there was an intermediary and the end user pulled the pin as he didn't want it sent to Japan to reco and then on to the USA as the freight bills would have added up.

It's a works factory motor from what appears to be late 85.

It's in average condition but the whole motor is there.

Thought you lot might be interested in some pics.

Nice! Piece of history!

Why would it needs to go to Japan for recon? Not suggesting it wouldn't BTW, just curious as to what they'd do there that can't be done elsewhere.

Thanks for sharing the pictures !

That clutch looks knackered. I'll help you out and send you a nice condition 750 clutch that even has a proper cover to keep the dirt out, you can send me that one back in exchange. I'll even pay shipping. Cheers!

The buyers agent is in Japan and that's what he does, builds and refurbishes oil cooled engines only. We could have done it until I sold all the 70.3mm works pistons we would have needed for the job.

You're too kind. Thank you. I'll pass on the offer.

That intake port looks big enough to swallow a child

Do you need some of these Cosworth pistons ?

#PA 0866 ?

I think a purist and/or suzuki historian would shoot me in my sleep if I put cosworth pistons in a Suzuki works motor but thank you for your offer.

There was a nice set of brand new cosworth 750 pistons on Eblag in the UK last week but they had no rings.

These are similar to the pistons in it but not identical.

I have a racekit head here too, brand new in the box.

And a racekit crank.

This was something that was an interesting find on the cams in the used motor.

Is this the set? Sorry, it was not Eblag where I found them.

Yes, i came across them too, and the 70.3mm reminded me of your engine.

I am pretty sure that Cosworth made pistons for Yoshimura back in the day.

You guys get the coolest shit over there.

A very fortunate few get to play with those toys, the rest of us just look on whilst trying to be cool and pretend it's no big thing.

I believe a post on the internet made me believe that but I am not entirely sure, I offered these to the engine rebuilder and he refused.

I am lucky to have a boss who is a hoarder like am. Not many would think there were trick parts in Oz.
