While I was away for a couple days, the mufflers arrived:



Got them installed:



Hooked the battery up, and fired it up! Sounded great, but mostly 'tickety-tickety-tickety.' No vid of that today. Couple details to deal with, and I should be riding it this weekend.

Rare day off and a cruised this entire thread. Very tidy build.

Good on ya'. I minor amount of maintenance, a rubber change when needed, it'll serve you well for
bunches of miles and years to come!

That can't be said for some of the new thingie-bobs coming out of BMW today...

Rained yesterday. But it dried up today! Got out and about on the moto!

It fired right up, and I discovered it needs less than 30 sec of choke in this weather--it actually stalled out three doors down. Once I figured that out it ran great. Here's the return from the test run (clicky on the picky):



After that, the boys and Mrs. melville all got a spin around the neighborhood. Good times.

Felt good to put my own discoloration on the headers:



After that, I took the passenger pegs off, as I am not qualified to take a pillion any distance. Mrs. melville took the boys out for the afternoon and said "Put your gear on and RIDE, you doofus." She also told me to be ready to dig a hole when she got back mit the boys, as they were tree shopping.

So I got my ATGATT on as they left and had a wee ride. Went to the gas station and filled it up--nice to buy 200 miles of gas for less than $20! Then off to the Bottoms and all the way out Mad River Road:



I was riding to break in the rings--on and off the throttle in 2nd and 3rd gear, going from 2K to 4K or 5K rpm and back down. Had a few moments of "What's that smell?" but nearly no "What's that noise?" Bounced around the Bottoms (our road department hates us) a bit more, then hustled home and got into my digging gear.

Bike need a spot of tuning--idle is about 1500 per the MotoMeter, and the synch is definitely off a bit. NO FLUIDS ARE LEAKING! This is definitely the fastest thing I've ever owned. I'm both looking forward to and fearing a bit trying out 4th and 5th gears.

Yeah, found the source of the "What's that noise?"



I put a plain nut on it, but the stud is spinning. I have the Genuine BMW Part coming at the BMW car dealer, and I'll deal mit the stud at that time. Maybe a thread repair, maybe JB Weld. Had fun calling the car dealer (I'm 200+ miles from the nearest BMW moto dealer) with a part number and nothing else. When he described it as "Cap nut, $3.80 ea." I figured he was close enough and I let him know it was a MC part. He was a bit surprised and pleased to learn this.

I checked the valve clearances and found that they'd moved a bit in all directions (no more than .004"), checked the oil level (OK), and took a closer stab at baseline (non-running) carb synch.

Looking forward to Moto Commute Friday!

Stoked for you! Maybe our paths will cross next time I'm down there.

Just enough rain to cancel Moto Friday. Next week, maybe Moto Monday and Moto Friday!

I knew after my shakedown run last Sunday that the carb synch was way off. I could even hear the cylinders fighting with each other a bit as it ran through the range. The bit I ran it before I disassembled it I had it going well and smoothly and I left the idle mixture and speed settings where they were working well on the old motor. Those settings were OK to start with, but the new pistons and rings wanted something different.

Before I'd used the same techniques I use on my dual carb VWs for idle adjustments--basically shut off the mixture screw one side at a time and observe the change in idle, and make adjustments on the other side. Try to remember how many turns of the screw it took to shut things off!

But I kept reading about this ignition shorting method. "Just make a tool out of some old spokes." I saw pictures of these shorting tools on the InterWebs and in BMW ON, usually looking like this:



I'd look at those pics and wonder "Is there a hinge I can't see?" "Howz that work?" I was going to go about this using my VW method, but I did take the time (a LOT of time) to read SnowBum's write-up and I saw the light! It was this bit:

You're spozeta use ONE ON EACH SIDE BETWEEN THE PLUG AND CAP! So I got my bag o' defunct spokes:



Got a couple that didn't have frozen nipples and cut them a bit shorter mit the big boltcutters. Now for all y'all who were as confused as me about how these things work, HERE ARE SOME PIX TO 'SPLAIN THE PROCEDURE:

Remove spark plug cap and install the ShortMeister:



Put the plug cap on the end of the ShortMeister:



Start the motor up! When the idle settles, get the Big Screwdriver and close the ShortMeister to ground on the cylinder head. Make sure you hand is only touching the plastic! DAMHIK:



So I did all that and found that the right side wanted a lot more fuel and a bit less air and made the relevant adjustments. After that, I held it at 2500 and shorted each side in turn, finding that my static readjustment of the cables a couple days ago wasn't far enough off to be worth fiddling. We'll know more with the next ride later today or tomorrow. I also expect things to change as the rings get comfortable with their bores.

OK, I'll be the first one to fess up and say I'd never managed to figure out what was going on with the ShortMeister method for carb syncing ...

Thanks for posting the pics ...

However, I am somewhat surprised to see such crud encrusted spoke being used in association with "Ernst" ... given your proclivities I was expecting them to be mirror finish ...

Looks like your carbs have a vacuum take-off port on them. IMO a much easier way to synch the carbs.

I posted that for all the Airhead folk like you and me who weren't quite getting the message from the various write-ups on the ShortMeister method.

I am not polishing my discards. Speaking of which, anyone who needs a ShortMeister need only send me a PM with a mailing address. I still have 50ish spokes to make them from.

I'm considering that--maybe try that clear tubing/drop of ATF method.

Great job on the rebuild, I have been silently following along as you massaged each piece.

Must feel good now to get to break the motor in again and enjoy riding the fruit of all your labor.

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Feels most excellent. Got some more break-in miles today, 35 or so. Experienced 4th and 5th gear, and wound 3rd out to 6K for 70 mph or so for some load and unload on the rings. Made a few stops, first right near the house:



Then down the road a touch:



And just a bit further:



The first two are historical markers, the third is an odd ship. Not a cruise ship on which normal folk can book passage. More like this. I have no idea why they stopped where they did--I heard something about "taking on provisions" but there are no sources of maritime provisions there unless you are running a crab boat. Not a place for the beautiful people by any stretch. Hope they were able to keep the tweakers from coming aboard.

Bike ran great. The OP sender is leaking a bit right out the spade and will need to be replaced. It sure looks like a VW part. Idle was a bit high when I came back, 1800ish per the tach. A few minutes mit the ShortMeisters had it right where it should be.

OP sender replaced, and then it was time to get out and about on the motorbike today. Then some work on the bike.

Went here, just a touch inland and a mile or two up a twisty mountain road. Road was nice--they repaved it in the last couple years, nice and smooth. Historical spot:





I'm more than a little disappointed in the spray paint.

Back home, and with the oil hot I drained it and pulled the filter apart:



Looked alright for new bore and rings. The big bluish pieces look like the sealant I used on the cylinder bases (Kuril T) spooged out and caught by the filter. No big metallic bits!

Put in the regular oil (not the special 30W break-in stuff), a new filter, and called it a day. My local Airhead guy is going to check the bike for any glaring errors this upcoming Moto Friday.

Had an issue mit the handlebar--couldn't get the throttle all the way on, and so couldn't install my internal expanding bar end mirrors. Seems the bars were made for older BMWs with simpler controls.

My local Airhead guy hooked me up with a Flanders 'sidecar' bar, like so:



New bar is the one behind--note that is it narrower in the middle and has a longer grip area. A new difficulty presented itself--it's a bit beefier than the one I had (new bar on the left):



And again I had difficulty with the bar end mirrors. So out came the Dremel to fix the problem. Nothing like the smell of burning rubber:



The mirrors fit the bar now, and all will go back together in the next couple days in time for Moto Commute Friday.
