six inches longer!!!

[Mike]

Oh, you mean this. Found it on craigslist last year. It looked lonely, so I decided to give it a good home

Nice!

[Lars]

Nice!

Thanks. I like it too. 9 years without a motorcycle was about 8 years, 11 months and 3 weeks too long. Never again.

[Familyman]

I have a shop that may be able to do it. Thanks Lars for the info.

Installed

Installation complete, but not ready for prime time. Gotta finish the cam swap so I can drive it.

Those are sexy!

Wonder if my wife will agree...

Lars,

Those are very nice. The frame brackets look like they won't be too much of a catch point if you're sliding over a rock. Very professional installation.

[crawlin68]

I agree, I like the frame mounts! The arms are sweetness too!

[69crawler]

Those arms came out nice. What paint did you use? POR?

[crawlin68]

Does it run yet???

[Lars]

I wish I could take credit for the frame mounts, but they are Poly Performance originals. Amusingly one of the details that hung me up for months (years?) with the project was getting some brackets made. Then a year ago I discovered that PP was selling a bracket that was almost identical to what I had drawn up in SolidWorks. And at the time for only about 25 bucks each. I think the price has gone up about 10 bucks, but I think they are still a deal at that price. Really nicely made from 1/4" laser-cut plate.

Paint is POR-15. Single coat. I know they say you are supposed to use 2 or more, but I'm lazy (and impatient). Even a single coat seems to hold up pretty well on fresh metal.

Still not driving it. I discovered I needed a new timing chain while doing the cam swap. Only 30k miles since new on the engine, but apparently the stock silent chains don't hold up so good with a bigger than stock cam and heavy valve springs. I ordered a Cloyes set yesterday from Summit, but they had a shipping hiccup and it didn't go out till today, so it'll be here tomorrow. No matter. It's butt-cold in my garage tonight, so I don't feel like working in there anyway

wow!

Clean looking fab job. It is also refreshing to see the professional prep used to create them. my hat is off to you. Question?

How did you determine castor adjustment?

Thanks for the positive feedback.

The fixture I built took care of the caster. I don't know if stock arms have built-in caster or not, but it doesn't matter. I verified that the front face of the stock arm is perpendicular its long axis (it is) then built my fixture so it holds the arm stub perpendicular to the long axis of the tube. Thus my arms have the same amount of caster (or lack of it) as stock.

As it turns out, I cut the inner C's off my Dana 44 and rotated them back for more caster a couple of years ago. Enough that with 4.5" springs I run 2 degree C bushings and still have 5 degrees of positive caster. The extra 6 inches of arm length also flatten the angle between the arm and frame, which should give me almost another degree. I'll report back when I get it running. Maybe tonight, though if it's as cold tonight as it was last night I'm gonna wait. I'm a wuss about working in the cold & dark if I don't have to.

Of course your new production fixture will have a shim stack to dial in whatever castor you want.
