Got the shock. Looks new, except for scratches on the spring.

I read a post by someone that said the shock length can be shortened internally by any good suspension shop.

But the shock needs to be shortened almost an inch. There's only 1.750 inches from the body to the bump stop. If the shock is shortened internally, there would only be about .750 inch of travel. Plus the spring won't fit anymore.

Tomorrow, I'll look closely at the lower adjustable eye to see how much can be modified.

You can probably cut the jam nut down to half thickness and shorten the lower rod end thread to get it to screw in all the way. I would try this before spending money on a suspension shop, if you have to spend a few hundred to make it work it kind of defeats the purpose. You also have some preload left to come out of that if you need it to sag a bit more when you are on it. If you install it and the rear wheel clears the ground by a quarter inch or more you will be in the ball park.

Thought I could just loosen the locknut and spin off the lower eye mount.

Oh, hell no. It was locktighted in like a bitch. Threads don't look great.

Wonder how much a bottom tap & die in this size would cost?

I wouldn't take the nut off until you clean up the threads (sorry if I'm pointing out the obvious), a metric thread file will do the job if used carefully. If you are going to run it in deeper that damaged bit won't matter anyway. Get a round wire brush (preferably brass bristles) to clean out the female threads before you splurge on a tap for it, you might have to spend $20-30 on a bottoming tap in that size, but flip side is now you can tap it all the way down.
Anything that feels like it has loctite on is simplified by the application of heat, doesn't take a lot, but it will be hot to the touch.

Quick note on the threads inside the shock.

It's fully threaded. There's more space above the threads, but you can't add more threads because the diameter is larger. No reason to get a bottoming tap.

New front brake lines arrived. Looks like the'll fit (after raising the handlebar).

Next, need to get the new rear shock installed and fix the front forks. Forks are topped-out and are very hard to compress after installing the new aftermarket fork caps. Not sure what's happening, yet.

Machined ignition surround out of delrin.

Gonna try to inlay it into a side panel. Panel isn't flat, so it'll be interesting.

you may have to make a washer shaped to suit the uneven surface.
i found its easier to do than try to surface the underside of the surround
post your solution.

I was thinking of just throwing a little plastic filler where needed. [smilie=dunno.gif]

Still working on that damn shock.

Trying to shorten it up as much as possible, without welding.

Had a little time today to work on the side panel. Chopping tomorrow.

Wanted to match the left side cover hole, but the post is behind the hole. On the right cover, the post is in a different place, and needs to be in front of the new hole.

Here's where I'm at with the R1 shock.

Cleaned up the shock and eye threads. Cut down the eye length to screw all the way to the end of the threads (with the lock nut on). Still too long.

Cut down the shock 4mm. Still plenty of threads. Got rid of the locknut and cut down the eye until it bottoms against the shock, close to the end of the threads (with the same orientation as the upper eye). Will locktite after fitting. Eye-to-eye measurement now 300mm.

Will see how it fits soon. Not sure whether to modify the shock eyes to fit the OEM hardware, or make new hardware. Whatever's easier for sure.

Aligned the panel holes the best I could. Fortunately, they're on opposite sides of the bike. :smt003

Planning to use some appropriate filler on the gaps before the side covers are painted.

Anyone know the best type of adhesive for delrin to polyurethane?

Anyone know the best type of filler for polyurethane semi-flexible panels?

Haven't found any way to hold the ignition bracket in position for welding.

Need to be able to put on and remove the side cover to check the position.

Will keep trying.
