You guys know me...no info before the ride report, but I'll tell you it made it back to the house under it's own power.

I 'spose I could give a few riding impressions without giving away the story.


I want the 9 gallon tank or whatever it is for these things, I can't tell the difference between a full tank or an empty tank right now and the extra range would be very nice.

The .49 front springs are a good match and keep the riding within the limits of a 500 pound motorcycle. If anything I need a stiffer rear spring and need to pull the rear frame section over where it belongs(PO crash damage tweaked it), since it rubs on full stuff.

I find the back and forth throw of the boxer engine extremely tiring and annoying. Anybody making light weight forged pistons for these things? BMW should have built a flat four instead of the new water cooled boxer, a balanced and smooth flat four would be fantastic for a bike like this...yes, I have a line on an OldWing.

Brakes are perfect.

Definitely have to do something about the effort it takes to twist the grip. It's okay at trail speeds, but the further you twist the more the springs wind up on the carbs, very tough to keep the grip twisted at 80 MPH.

The jetting is great. I didn't mention earlier as it was causing bunched panties, but I dropped from a 165 main to a 117.5. We get 40 MPG at a constant highway drone. I'm going to lean things out further on the rest of the circuits as a heavy hand on the trail sucks the fuel very fast, runs great though. I think that a bunch of the issues I was thinking was fueling was actually the loose cylinder head.

The little Lithium Ion battery did great. If one is in your budget it's a great way to drop ten pounds off just about any bike.

I need to extend the sidestand, I had to have the help of the missus just about every time I got off the thing in the dirt.

Thanks, not a bad price either.


Are these Nikasil coated cylinders?

I'm sure you realize, but just in case, the crank has 2 throws, spaced 180°. Pistons travel in/out simultaneously. If you're feeling a 'back and forth' motion it might be cylinder balance, caused by one of a host of things. Maybe compression on the formerly loose cylinder?
(The usual apologies if you already knew all that.)

How did that re-torque hold up?

Rumor has it, yes.

I've felt it on every boxer I've ever ridden, I'm sensitive that way. The engine rotates the bike to the right, then throws back to the left. No big deal for most riding, but if you putt around at less than 20 mph for two weeks it starts to wear on you.

The re-torque held up, no issues there.

Probably cost me a grand for parts, over bore and plating. Maybe later.


Just got back from BMW, picked up an oil window kit and all the bits to rebuild the oil filler.


Thanks again for all of your help, I appreciate all of your insight!!

It's a wonderful place, this land of They All Do That.

I'm glad everything held together. Cheers buddy!

All it needs is a 3800 rpm idle.

Oh yeah, I need to change the fuel tank venting back to how BMW did it. I thought I could vent it through the cap, but under a heavy load the tank bag smothers it too much and bumping along in the dirt you smell gas too much. I'll run a tube from the vent connection at the cap down thru the tank, do a bulkhead fitting at my block off plate, then run a vent hose from there out to the back of the bike.


Uploading pics for the ride report...
