1979/80 CR390 Works Hybrid Project - Passion Inspiration Action

The only thing in your pit that day were two old dudes and a couple of trick Maico's.... we had to head down the vintage line to find a 15 year old blonde that was more to his liking !

Scotts Damper mount for Vintage CR390 + Top Triple

I have seen a lot of bar mounts. I wanted something different and unique for my Hybrid Restoration. I have been extremely happy with my Scotts mount for my modern TC450 so I started looking all over the net for bar mounts. Reading all the stuff that you guys have done in here. Wanting fat bar mounts but also remembering how harsh the old bikes were ... so that got me thinking...

I called Steve at Scotts Performance in Montrose, California. He rode Husky's back in the day and owned 250's 390's, 430's and 500's from 1979 thru 1984. Together him and Eric (also at Scotts) went on a mission to create a unique and as far as I know, "one of a kind" set up for me. I'm using CR500 Husky Forks and triples off of a 1983 CR500 Husky on my 1980 CR390 Hybrid. Steve did all the math as he was familiar with the old angled bar mounts on Husky's. He also had rode and seriously raced Husky's back in the day. He knew where the bar mounts should be to make the bike turn and the height to put them at based on my size ( 6ft). Eric asked me to ship him my top triple so that they could actually work on it there at Scotts! Two days later, this is what they both came up with. Scotts one piece 85 MM top damper mount for fat bars. 29mm rise lowers. New bolts all the way around.They even gave me free shipping!

I have never had less than exemplary service from Scotts. This time they went above and beyond. Damper is perfectly centered on the steering stem.

I custom polished my top triple and love the way it shines and contrasts with the other parts now. I have NOS new Cagiva mounting rubber for when the bike gets assembled as well as new 8mm x 35mm 316 SST socket head cap screws for the triple.

Here are some Pics:

You're SM project gets most of us jealous so I guess it's only fair that we get all the women.

Rear Wheel Bearings and Rear Brake Backer Assembly

Nice cold rainy day today in Corona... perfect day to hang in the garage and work on my rear wheel assembly. FOr the most part you guys have seen the wheel and tire. Now it is time for quality German Bearings, new foam for the axle spacer tube, new seal, Dull Nickel plated and restored brake cams and arms, new o-rings, EBC pads and heavy duty springs and a custom powdercoated rear brake backer plate.

Laying it all out:

Those close ups really show how far manufacturing and quality have come. Not a knock just an observation.

Half Rolling Frame

I was thinking of HWY when I set up this shot....

Half rolling frame. Sorry to have the nasty unrestored shock in there. It was either that or a 1X2 wood Vampire stake but that seems to have been done around here before ......



And another less artistic shot:


Coming up: triples, bearings and bars and then........fork tubes and a little trip to Race Tech.

No Diss intended! LOL! You , my friend, are going to have to frame that wood stake that we have all grown to love.
