Eight Pounds and 40 Stone Build

[bonneblktrk]

One to hit me and one to hit the motorcycl', I'd probably get it backwards.

I have been waiting for the rear wheel to arrive from Calif. so thought try to make some fork extensions.

I put in the set screws for extra security, probably don't need them when pinch clamps are tightened, the tubes can't move vertically. What little tolerance I ended up with on the boring can be taken up with shim stock, one needed .006 and the other .0015 shims with little play. Turned the final outside pass with a pattern similar to machine marks on the fork tubes.

This amounted to 1.750 extension of the forks. Haven't verified the final length will be what's needed yet. I can machine the top triple part of the extension if being lower is needed.

Lookin' good! They might get you right up there without changing tire size.

I mounted my 120/90-17 tire on my Busa rim today....figured you might want to see what that looked like, so here it is:

Couldn't quite see in your pictures, did you put a washer under the stem nut, or did you just preload the bearing with the nut?

[bonneblktrk]

Yes, there is a keyed thin washer under the stem nut that preloads the bearings. The nut on the upper tree still needs a washer in this pic.

Tire looks good, is that the stock size?

I am going to put the forks on the frame tomorrow to get an idea what it will work out to be with the extensions.

[wingrider]

This tire is oversized....I think the stock is somewhere around 120/70-17. I gained almost 2" with this tire over stock.

Care to make another set?

Why don't you PM me.

[bonneblktrk]

Got the wheel today, it looks like new. Mocked it up some. The massive sssa would look cool if it can be fitted, still out on that.

[Easter]

Definitely not your father's GoldWing! Looking good.

[Markn]

Nice, i;m going to follow this project closely

[bonneblktrk]

Thanks for the comments Easter and Markn. At least the front end is done, makes me feel like some progress. If this sssa isn't possible, we are considering a tubular sw using the GL1800 differential and using the GL1000 swingarm pivots on the frame and not alter frame. Not afraid to alter frame but mounting sssa may not be symeterical, and it would not look professional, "hack job".

[wingrider]

Lookin' real good! Depending on how low mine sits, I may see if you'd make me a shorter pair for my Busa forks. Keep up the good work!

Please advise if you notice me doing something unsafe and stupid and could hurt me!...I put in the set screws for extra security, probably don't need them when pinch clamps are tightened, the tubes can't move vertically

bonneblktrk, The biggest stress that effects handling (and safety) on your forks is twisting.
Maybe I'm not reading closely, but I don't believe you have the necessary three
locking points at the top tree to make the top and bottom trees a single fixing unit.
That is the principal behind inverted forks.
Just my observation and opinion.
Enjoying the build keep up the good work.

I was looking at them and wondering about that too. Maybe if you ran the "spacer" all the way from the top triple to the bottom triple.

[Fred Camper]

Seems like the spacer from top to bottom of the tripple tree would firm that up nice. Then the set screws are just holding the tubes to the spacers and that seems more sound structurally than what I see now. Just another opinion from the gallery of gawkers.
