Dear sirs!
    Could you please send an application for employment to your facility? My pay would have to be very minimal and promise that I will work hard and try even harder to keep the drooling to a minimum!
Thank you for your attention to this matter!  :laugh:
   Love your collection!!!!!!!!!

are you going stock or fixing all the irritating things ie. carbs , exhaust,rear sets, brakes, general weight issues?
they do have worth $$ stock although I will never understand why. they made a lot of them and they are not that "special"until you start selling parts off of them. I will admit that there is something great about this frame when you lighten up this bike with spokes and aluminum swinger, modern brakes,  they just feel a tiny bit stiffer than the previous RDs.....it might be in my head, but I swear I can feel it. I have never cut one up due to prices they command with all the tabs in place, but I am sure the result would that little bit better magnified.
I have a couple, and I am very fond of this one for that indescribable something.

I have all the factory parts except for a few airbox pieces, so the plan is to put it back as close to factory as possible.
I hear conflicting stories of actual production numbers of the Daytona Special, does anybody know for sure the exact number of bikes produced?

Thanks,

Nice, great to see another daytona getting back on the road. My pop has one he bought brand new in '79, never been rebuilt, bone stock been parked in the grandparent's garage for the last 20 years. It will be my next resto project, new rubber, crank seals and a good cleaning it should be ready to rip!

My local Yamaha dealership said Yamaha only made 5000 units of the 1979 Daytona Special, which represented 28 days of production.  Not all the units produced were sold in 1979.  Enough parts were made that Yamaha decided to make one upgrade (ignition) and build the units sold in Canada (and maybe other places, too).

We're 2000 km apart and my 79 is only 101 numbers from yours , my 1980 is at 141  .

3J7-02 I guess this is for the 1980 models , not the production numbers . I don't think they sold more than 1000 of the 1979-80 in Canada .

Hey Daytona 570....i have daytona 569, i just bought it in boxes from a guy in Vancouver who has had it since he was 16, i found out through my yamaha dealer that it was sold to a August Weimer on 1980-04-07, the selling dealer is stated as Toronto Traffic Dept  whatever that means?
I am currently building it, got the crank out getting new seals/bearings, cylinders getting Wiseco pistons, Vaporblasted cases and wheels etc, trying to figure out the route of the wiring harness and i think the metal guide on the left headstock is bent out of shape, if anyone has some close pics that would be appreciated, i will post some here soon
