1979 YZ80F
« on: May 18, 2018, 10:23:24 PM »
Hi gang,

I have added a new bike to the stable.  A 1979 YZ80F.  Had one new back in the day. Had a good season on it, as it was a rock solid mini racer.
Anyway, i have started collecting parts and am stuck for a filter cage. I believe the filter cage is the same for the E, F and G. Part number 2J5-14458.  I have searched all my regular hunting grounds and i have hit a dead end.
Anybody have a spare tucked away? Pic below of the cages was grabbed from Facebook...

The idea is to get her ready for the boy to ride (with the XR75) in some VMX meetings just for a bit of fun... then do a full rebuild later on.

Will add progress reports..







If anyone has any other nos parts they want to sell, i would be very interested. Especially plastics..

Cheers,

Can’t help you with parts.

I also has one new in 1979. Won the A grade club championship on it.
(Got beat by the fast guys on their YZ80E’s the year before, when I was YZ80D mounted. Big advancements each year in those days.)

The F was a big step back in the day for 80's was it the first 6 speed?
You could get a metal fab guy to make one from 5mm 316 stainless bar?

Can’t remember if it was the first 6 speed, but it was the first with an internal rotor ignition. The far less “flywheel” made for a free/faster reving, more “modern” engine. They put a brace on each side of the swingarm as well. The single brace on the E was far less strong.

Thanks for all the input guys..
If you don't have one Iain, then i will have to make a temporary one out of SS tig wire and tig it together.  Will be strong and lightweight.  But i do want an original for the future restore.

Pic below of me on the F at the first round of the WA state titles.. I had an aftermarket 17" front wheel..



More stuff to come..

Cheers,
