Yamaha guru needed

I have found something a Steve Baker bike 2 stroke 3 pipes and a side fill tank. Going up in the AM to look at it in person. He says he has a fill can and stand with it he does no know anything about it found in a warehouse be sitting for a while does not run he told me he took the carbs off I told him stop do not touch it anymore the picture I have shows the red white Yamaha colors with the blocks of red going down the side.
So the question is how many side fill tank bikes are out there?
Factory markings to look for?
Any help would be very helpful....

 

Let's see the photo.

 

Well I got to go take them first all I have is a post card with Steve Baker riding a bike. And the guy says it looks just like the one he was riding...

 

Frame and engine numbers if any?!?!?!

Yamaha didn't have a triple, but didn't one of the last versions of the TZ750 or maybe 500 have 3 down pipes and the 4th one snaking around and exiting high through the side of the tail? I don't know if any of those were customer bikes or all factory.

 

All mono shock TZ750's had 3 under and one up and through the frame. Someone that does not know what they are looking at might see it as a triple. Or it could be a Kawi?

As far as a quick fill there we quite a few bikes with them, for anyone that was running the Daytona 200 pretty much had to have a quick fill tank.

As far as things to look for,

1. If it is a 4 cylinder it is either a TZ750 or a TZ500 although in the US I would be surprised if it was a 500. If it is a 750 it will have 409 prefix cylinders and reed valves. If it is a 500 it will be piston port and depending on the year it will have paired cylinders or for a later model individual cylinders.

2. If it is a Mono shock 750 and has a steel swing arm it is late model production E or F model 750

3. If it has an Aluminum swing arm it may be an OW based Factory bike.


If I can be of help I will PM you my info/number

 

Charles will be on in a sec to edumacate y'all on the Ziegers triple.....

 

On the quick fill did most use a stock tank so it would have the factory flip up cap still on the tank. Factory kit stuff was Alu. right on the swingarm and tank
I just need to see it up close my friend does not know that much he said it had three pipes on one side. If it was a factory bike it would only have a few numbers on the neck right if any. If you wish I can call you when I see it or text you a picture.

 

If it's a 750 the serial number will start with a 409-

A warehouse find Big TZ?! Holy crap! Post a pic and we'll know pretty quick just what it is.

 

Tanks had both the flip cap and the quick fill. There may have been some that were quick fill only, I believe production bike tanks were flip cap only.

I have pictures of two of Bakers bikes, the OW31 and the YZR750 both were works bikes. I was wrong in the earlier post. The 77 TZ750D was the first production monoshock, it has a Steel (crmo) rear arm. It was the production version of the OW31. The YZR750 has an Aluminum swingarm and other special parts that may have included 7 transfer port cylinders.

He may have had other production based 750's there are specific things that will identify what it is.

The PM system has changed I did not realize messages were public so I pulled my phone number. If you took my number down you are welcome to call me I have the Yamaha Factory TZ history by Colin MacKeller handy.

Drop me a message if you need my number.

I looked at the bike in Vegas, it does not look like an OW31 unless it had the swingarm retrofitted. It looks like the YZR750, if it is then you may be looking at the OW31 or something else.

Missed your number in the general thread tried to call but it was after hours.

 

Baker bike

I have the remains of a Steve baker ow29. Many parts are missing. You may have found some of them. Call me 908 995 7827

I'm actually more interested in the bike in the background in the third photo.

 

Well!?!?!?

 

There wera, and are, Yam-based triples, both air-cooled and water-cooled…The 1977 350 World Champ was Katayama on his un-official Yam triple, which is now owned by Ferry Brower….and Karel Zegers built his own Yam triple in 1978-1979, which was then reproduced by Spondon (12 or 13 bikes total).

 

Zegers 500.

 

Yep, that's what I had, only w/ wire wheels.

 

Well whats the verdict ?

 

yea what happened?
