Title: Yamaha serial numbers
Post by: Rossvickicampbell on September 29, 2016, 02:09:04 pm
Guys - does anyone know how to identify a Yamaha part by it's serial number - not part number.  I have an AIR shock for the YZ360B - Yamaha don't recognise it but are still chasing for me and it is not a listed part anywhere we can see - serial number is 110581?

thanks

Rossco

Dont yamaha use the first few digits of the model code in the part numbers? perhaps non Jen You Wine?

Generally if the part is made by Yamaha it will have some kind of identifying/part number cast into it. If the part was outsourced then the number may not relate to anything Yamaha.
Me thinks....

There were aftermarket air-spring conversions for early Monos. The one I have has a red painted aluminium cover over a rubber bladder (I think - I haven't pulled it apart).

For some reason I can no longer insert images into the forum - or use any of the icon shortcuts - but here are a couple of pictures for those interested enough to have a look.

cheers

Rossco the air springs were not Yamaha . there were 2 types a alloy cylinder with a air v/v as you have pictured and a bladder type as Nathan has said . one was a Fox and I forget the other make .

Iain - I did not think Fox were doing anything in 1974?  Way too early for them?

Hi Gents

Reeder and Girling both made gas springs, any one have pictures to help Rossco out?

Fox were making spring coil / oil shocks in the early to mid seventies but not for Yamaha mono shocks.

It was not a complete monoshock the air spring was a after market kit that fitted on top of the Yamaha mono . I remember them but I'm stuffed if I can remember their name .

The Fox emulsion shocks came out in 1975
Single chamber Fox air shocks 1975
Dual air chamber Fox air shocks 1976

Fox airs were still in prototype/testing in 74

you need to realize that many products came out a few years later after a new model bike. So in 1976 or 77 or when ever you could buy suspension improvement parts for a 73 or 74 model bike for example. It does not mean they are legal in todays pre 75 class though.

Oops my bad. but i do remember them and i also remember one of the guys who i cant remember  his name but he had a tricked out suspension back when I wasnt so grey and running around Failford track and its a very foggy memory from back then but Im fairly sure i thought it was weird that a tyre manufacturer made suspension bits for MX bikes. It was a tyre brand that dont do bike tyres and I think it was firestone.

Ottows Werks may have done something for Yamaha monos. I know they did replacement internals for the 76 Yamaha air forks where they sold different pistons for the canisters on top of the forks.

What you've got is the same/very similar to the one I have. Will compare/take photos when I get home.

just received an email this morning from Thor Lawson - looks Like Gibbsy might be on a winner as Thor thinks it is an aftermarket Reeder set up also.
