Flummoxed! XS650SK Front Fork Alignment.

[gggGary]

Thank you! I believe I have some uncommitted triple clamps. When I dismantle this thing (maybe next weekend) I will check the fork tubes with a dial gauge.

What size will suit me best?

Doesn't really matter here, so the $19.95 set?
best if you can clamp them to a flat surface.
The fork/parts offer will remain open til you release it.

I will get with you this evening. I think it's likely my best option.

I slowly dismantled this this piece by piece. I found nothing until I removed the lower clamp. The bottom isn't machined, so placing it on glass plate doesn't say anything. A straight edge inside the loop as per the video has me believing the lower clamp is indeed bent. Still double checking and digging about for another.

Closer scrutiny says the clamp is OK. Hopefully, I can check the fork tubes next week.

The other day I was lookin' at carpenters levels at Home Depot. Mine's so old it's hard to see the bubbles. Anyway....
Every damn one of 'em had a slight twist in the frame. Jus' sayin'.....

For carpentry work I still use my Dads old spirit levels (and other tools), they are decades old but accurate and reliable. I have a few various modern levels but for accuracy dads do the job. I fit expensive wardrobes and media wall systems (typically £10k+ for a 6 door robe) so precision is expected by the customer.

Left fork tube is bent. I’m no longer flummoxed.

So, how did you figure it out? Just spinning the tube in the trees, or removed and rolled on a flat surface?

We chucked it up in a lathe and measured them with a dial indicator. The left tube tube is out of limits.

Does anybody sell left fork tubes individually?
















Coat, hat...

If I buy new, I buy two. The Forks by Frank are heavier gauge metal than stock at last report.

I prolly can come up with a straight one or make it so.
It's not hard to straighten them either.
And finally this conumdrum is put to bed! (we hope).
I have some Utubies about straightening there's a reference here somewhare.

Seems to me that a person with a lathe in his shop would also have V blocks and a hyd press?

That's more bother than I wanted to be. I'm just happy to know what the issue is.

It didn’t fix it! (Replaced bent fork tube.)

Isn't this the bike that broke a rear shock more than once?
I'm 5 states away but: Think that bike has a bent frame.

or swingarm. Good shock would cause a twisting moment. A few hard bumps... and bent.
