Hucky will sell me just the pistons (plus a few odds and ends since i was on his site;))! Still, at $100 a piston, you'd think these brakes would have a better reputation;) And I live in San Diego - we don't get the same sort of stupidly oppressive heat/humidity you do;) (and it won't snow later;) )

I'd do the offer of the replacement caliper.
Yeah, i'm sure it would be hard, but as long as the drill bit and helicoil tap didn't damage the conical bottom (and I drilled straight!) I see no reason why it wouldn't work, but really, with the offer from wirewrkr it didn't make sense to go through the effort. now what do i do with this chunk of aluminum... its to big for a necklace.

You could, just for fun, go ahead and tap the thing just to see if it would work. What better to practice on than a piece of crap?

The drill bit has a taper on the front that will probably not touch the tapered bottom of the hole but the tap to make the threads that the Heli Coil will go into has a very long taper to it. You won't be able to make the threads with out destroying the seat of the bleeder screw. The bleeder screw seals against the bottom of that hole.

I would have had to get a bottoming tap kit. That's really why doing it didn't make any sense - the cost of the helicoils and the bottoming tap set would have been more than an entirely new(to me) caliper!

Benthic,

Just found your thread. Good reading. I too am rebuilding an airhead. Mostly cosmetic stuff still. Check out my thread and let's compare notes. Ha, we can go for a ride when I get my BMW running as I live in The OC... Actually we can go for a ride any time as I have 5 bikes to choose from (life is good).

List it on Ebay for what you paid for mine, just be honest and state " needs simple thread repair in bleeder screw hole"
Some one will probably buy it at that price.

HA!

I just put my check in the mail to Hucky's. Now I have to wait. Have I mentioned that I hate waiting?;) Some good news - I think Renner has some time to help me sort out my front end this evening:) If you haven't been watching, he's been going to GREAT LENGTHS to sort his own new front end out:)

TINK - i've been following your thread as well:) I love seeing people do this kind of thing. Threads like yours definitely helped motivate me to do what I'm doing:)

Having a bike to ride while rebuilding one is the best way to go;) But I can't wait to get on THIS one;) With any luck mine will be road worthy by the end of August... then I stop riding my maintenance/worry free 2007 Honda;)

I MUST RIDE every day, or, like a shark, I die.
After reading (part of) your thread I went out to the garage and got to work. Thanks for the bump start.
Hope to meet up one day and compare beemers Not sure when mine will be back on the road, but sooner than later is my goal, hopefully before the first snow falls... Snow!? in Huntington Beach Hmmmm...

Some fun progress tonight! Renner came by and helped me with the front end:)

First, we put the bearing races in the steering stem, and the bearing on the bottom clamp



Then bearing in the top


then we put the forks in and measured them but the were out of parallel pretty far, but we throw on the top clamp



THEN!



and



BOOM BABY! Thanks Toaster Tan!! we also did the glass test and they were very tolerable in that plane as well:) ((we had measured the forks before installation and they were pretty damn straight too))

Then we had some fun:)


head light brackets and clip-ons:)

Then Renner took off and left me to my own devices...



I felt i had to throw the control perches and headlight bucket on just to see it... now i wish I had put the tank back on for this picture... oh well, next time:)

Then I finished modifying the headlight bracket that holds the ignition



had to drill it out and make the shoulder bigger to accept the nut



Perfect!

Then I felt ambitious and tried to start putting the forks together. I think it was Mike V. that gave me the idea to use a soda can instead of ruining some feeler gauges



and I put the stops in the bottom, but had to stop. I need to do some reading on the fork inner bits to make sure I put it back together right.



and then I called it a night. But that is not all! Wirewrkr's caliper showed up today!



THANKS AGAIN! I'm almost back in business! I ordered SpeedBleeders today too, so hopefully all my brake parts will arrive close to the same time:)

Ha, yeah I saw yours this morning:) Sadly I've forgotten how to reassemble the fork internals. I thought I had taken better documentation fotos, but i'm a little shy in this area. With any luck Renner is going to stop by and show off his new front end and give me a few more pointers this afternoon...

Renner stopped by again and he helped me sort the fork internals and we measured the sag in his new suspension:)

I took a few more mock-up pics:) forks are assembled, but nothing is tightened down yet and I left the springs out. turn signals are just tied on for the moment...





With any luck i'll have a bunch more parts from the Beemer Shop tomorrow and will be able to make some real progress again:) fingers crossed!

Happy Friday everyone!
Spencer
