Thought I'd throw this out. Maybe someone has been through something similar.

Just got to look at my bike closely last night from a spill at Pahrump last Saturday.

As we attempted to put it up on the rear stand I notice that the left swingarm spool is missing. Can't lift. OK.
Then I notice that the whole tab the swingarm slider threaded into is also missing. Looks like the whole thing was ripped off.
My question is this:
Has anyone fabricated and welded a piece of aluminum to the swingarm to replace a piece like this.
IS there a better way to go about fixing this?

I wouldn't even bother but my rear stand is the spool lift type and I really like using my tire warmers on race weekend.

thx

I had metal spools for my stand, and it bent upwards with such force that it dinged the swinger. I don't want to replace the swingarm, so I was thinking I could get a machine shop to maybe pull the dent out and weld new threads on both sides for new spools. Next time I'll use a delrin spool/slider.

I sheared a swingarm spool off as well. Had the broken piece though.
Took it to a shop that welds aluminum and he welded it back on. No problem for him, a bit $$, I thought (around $30).
So yes, you can have a spool mount welded back on, dunno what you'd do to replace the original piece though.

any welder with an AC Tig machine (most shops) should be able to weld it. It's not much different then welding mild steel. A little different equipment, thats all

+1, my 954 swing arm spool tore off too... The whole design to weld that to swing arm is false. thunderace has threaded hole at the billet end part of the swing arm.

What's thunderace?

I've actually found a few people willing to weld it for me, however since I don't have the original piece anymore, it becomes a little more difficult.
I've also had several people tell me it's pretty simple to cut, drill and tap a piece of aluminum to replace the original but somehow that hasn't really helped.

If your ever in Canada look me up. I have worked with Aluminum for about the last 15 years and it is extremely easy to work with and the welding machines I use were made in the States. There has to be someone down there that has a small Fab shop that has the knowledge and equip. to fix you up and when it comes to the tapping use lots of oil and keep the tap clean of Aluminum chips. The drilling is no different really then drilling mild steel, just a little quicker and the drill doesn't get dull.

Being that I have welded for several years for the carnival, yes boys the carnival, I will tell you being good at welding aluminum is not an easy thing to do. If you find someone who can do it well charish them. Aluminum reacts to power changes not well, it can spatter and pop. I will tell you for sure, I would avoid someone who offers to Mig Weld it and their will be people who will offer. Have it Tigged as other people have said and some who knows what they are doing. If they weld it incorrectly they can actually damage the integrity of the metal itself.
