Re: R90s brake calipers

If the calipers are the same you will still need to switch the lines and bleeders so that the bleeders are on top. If the bleeders are below the lines they will not bleed. I don’t know why, as I’m not that smart, but I know they won’t bleed if the bleeders are below the lines.

Re: R90s brake calipers

I can’t say for sure, but I’m guessing they are different. I’ve never tried to switch them on a BMW.
I have, though, installed calipers backwards on cars before, and then spent two or three days trying to figure out why they won’t bleed.

Re: R90s brake calipers

Make sure the bleeders are ABOVE the brake lines. If you switch sides the bleeders will be below the brake lines and you will never get it bled.

Re: Doing push rod tube seals-need advice

Thanks again, guys, for the replies and advice. I assembled one cylinder yesterday, so the left side is ready to roll. I’ll do the right side in a day or so. I’ve ordered the four couplers for the intake elbows from Capitol Cycle so I can’t button everything up till those arrive. I haven’t taken the...

Re: Doing push rod tube seals-need advice

Thanks, Kurt. That seems to be the most popular way. Unfortunately I didn’t measure that end, I measured the top and the distance from the top. Your way is probably much more accurate.
Any sealer on the top where they go into the cylinders? Possibly green? I don’t think I’ve ever SEEN a green sealer.

Re: Doing push rod tube seals-need advice

Hey guys! I’ve been busy wrapping up a couple of other projects lately so the R90 got put on the back burner. I’m back to working on it now, so I’ll be running some more stuff by you. Again, thanks for your help. First, after doing some research, and reading Snowbums stuff, I’ve decided to leave the...

Re: Doing push rod tube seals-need advice

I forgot to mention that I did a compression test before I ever rode the bike and I got 135 both cylinders. I guess it’s possible that number has changed a little since I’ve wakened it from all its years of slumber.

Re: Doing push rod tube seals-need advice

Okay… I’ll try to answer some of your questions and concerns. First off, there ain’t no way this bike has 129,000 miles on it. A bike with that mileage shows obvious signs, and this bike has none of them. I DO wonder why the engine has been apart with only 29,000 on it, but I’ll probably never know ...

Re: Doing push rod tube seals-need advice

Thank you again, Gentlemen. Mileage right now is just over 29,000 miles. I pulled the heads and jugs off today, and the cylinders didn’t want to come off too easily. I got them off and noticed two things. 1) the base gaskets seemed to have some very dried up sealer of some kind on them. It was black...

Re: Doing push rod tube seals-need advice

Now that I’ve looked again, the gasket kit on eBay is from Euromotoelectrics. They’re one of the good ones if I’m not mistaken. Seems like I remember buying my caliper parts and master cylinder parts from them.
