AA is out of stock for a few weeks.
Who else has 'em?
Thanks George.
I'll try them.
Dave says he doesn't deal with step up studs.
Said the best thing to do is have a machine shop weld, drill and tap new holes.

I thought I could just drill, tap, and twist a 10mm x 8 in the new threaded hole.
Anybody else got a source for the steped up studs?
TIV store!

I know they have some step studs...not sure if those are in stock, but it couldn't hurt to try.
Definitely call if you don't see them on the web!
Thanks Chris.
I called Jake's shop.
He's out test-racing a new motor.
Any other ideas?
Try the dealer or a good Bug shop
Here is what I did to fix mine. May not be the optimal solution, but it was the only one I had at the time.
I drilled, tapped and helicoiled the head where I pulled the exhaust stud. I had to put in larger studs because I could get any step studs either. I then drilled our the ear on the heat exchanger so that the stud would fit.
Again, not the best solution, but it has worked for me so far. I'm sure it will backfire on me at some point.
Oh...also, I didn't have an issue drilling the heat exchanger because mine are not in the best shape and will need to be replaced someday anyway. I figure when I do that I will have the heads redone properly.
Bel-Metric in Tyngsboro, MA has them. Along with a LOT of other metric fasteners for German cars. One stop shopping. www.bel-metric.com
I also got my time-sert kit from them for my own exhaust stud.

Thanks Jim.
By the way, why did you go with the time-sert instead of an 8x10 step thread?

I used to repair pulled head studs on Kawasaki 2-strokes by using a Suzuki M8 x M10 step down stud. Been way to many years to remember the application, but go to a good dirt bike shop and I'm certain you'll find something that works. Some other MX bikes used step down studs as well. Talk to a MX mechanic.

Wasserboxer rocker studs are M8 x M10. The later 2.1 liter ones I think. They're a little too long on the 10mm side, but that's easily fixed.
Great news!!!!!! 8/10x56 and 8/8x56 studs will be here wednesday July 18th! We have in stock the 8/9x56 of course. Please let us know of your needs and we will send then.
This is the method I prefer...

I don't remember the exact measurements, but the hole size required to install the 8mm timsert is more than enough fill the same hole of the 10mm stud you plan on tapping for now. And then you can just use regular 8x1.25 studs.
Thanks for all the input guys.
I'll take a few pics when I make the repair.

Steve,
I found some step down studs at Sears Hardware.

You can buy more inserts if/when you need them.
I really like timeserts. That's the way I'd go (and in fact have in the past).
