You'll have to look at the Bing site, or maybe Snowbum's site, for specifics. Now you've got the baseline set. Also, make sure your throttle cables at each side have roughly the same amount of play, maybe 6 - 10mm, at the place where the outer cable sheath sits in the little adjuster on the top of the carb body. Then, I like to use the shorting-stick method to get the idle where I want it (on my R90/6, around 1000rpm), and even on both sides. This is adjusted at the idle adjustment screws, not the idle mixture screws... the ones that you level-set at the beginning. (The terminology can be confusing). Once it's roughed-in like this, I use the Harmonizer from here on. But I am assuming you don't have one, so let's assume shorting sticks. One I am happy that the idle is at the right rpm and both sides are contributing equally, I will use the idle mixture screws to set each side at their highest rpm. You might have to turn one in a bit, and the other one out a bit. Turn the screw an 8th of a turn at a time, slowly, waiting to hear an increase or decrease in rpm. Or use the gauge to see the rpms rise or fall. Once you've got the idle mixture optimized on each side, go back to step one and re-balance the idle stop screws (butterfly valve) as both sides might no longer be in balance since you've optimized the idle *mixture*. You might have to keep going back and forth a few times between idle speed and idle mixture adjustments til you have them both optimized. Once you're happy with those steps, you want to adjust the throttle cable where it attaches at the carb. start the engine and twist the throttle just off idle, and adjustments to the adjusting nut until both sides are balanced *with the throttle engaged a bit*. Some people make the cable adjustments with the throttle just off idle, some recommend running it up to 3000rpm and checking. This is much easier with a gauge than with shorting sticks btw.

Yes, this is my first rodeo with these carbs, I cleaned them out last night and everything looked good. I didn?t mention that all of the prerequisite work has been done, perhaps because I didn?t think I had to, but I will state that here. Floats are set, valves are set, idle mixture screw are out 1.25 (per initial spec) and cable adjusters are slackened, as they have nothing to do with the initial idle settings, but please note that I understand the adjusters for any throttle above idle, which would also require the gauges to set them perfectly, am I right? The sheath setting for normal use, is 1-2mm of slack, as this is readily available information online. I have no means of shorting the plugs, the man in the video, which I have watched 5 times, uses a pair of cut off spokes as extensions for the spark plugs, allowing him easy access to the raw metal for shorting with his insulated screwdriver on each side. Well, I don?t have any spokes to start with, cut off just so for this procedure, which is why I am asking for help with the gauges, right? Does it make sense that the gauges supersede the shorting method? Timing is set, the motor jumps to an idle from cold immediately upon pressing the button, due to an optical ignition trigger, a fresh battery charge, and, well, set timing to OT in the port hole, viewed at the correct angle. Right now, the bike starts, idles, and revs ok. The screws for the vacuum fitting are tight in their castings, and need to be removed, perhaps replaced by rubber nipples instead. I understand that I need to adjust the mixture screws to the highest rpm for each side, then balance them to 900 rpm, or close. Then, I can confirm the sync at throttle settings above idle- both of these procedures would benefit from the use of the gauges. I am getting an intermittent popping from the right side exhaust, pointing to the need to lower its idle, or raising the left side idle, and fussing with the mixtures of both. As I was trying to do this, no amount of adjustment on right carb throttle stop screw seemed to make a difference. So, I stopped, ordered the gauges, and asked for help here. Im not a totally dummy when it comes to carbs, I actually enjoy taking them apart. I have had my hands in perhaps 10 different ones - mainly for yard equipment or chainsaws, outboards, scooters, and tractors. Tuning is an art, I know I went through 3 months of jets, needles and clip settings on my mikuni 35mm carb. I get it, its touchy stuff. All I want here is a little expertise- perhaps just to confirm my guesses as to how to get it running right. Lutherville is zip 20193, about 15 minutes north of downtown Baltimore. Towson is also close. Thanks to all- porter -------------- next part -------------- An HTML attachment was scrubbed...

There's a few. Shorting sticks, various gauges (I have the Harmonizer and I love it). But basically, after you have the timing and the valves sorted, you want to baseline your carbs. Start with the idle stop screws, which open the butterfly in the carb body, at *just touching* the lever. or Maybe one turn in. But both sides set the same way. Then turn in the idle mixture screws (at the bottom of the carb body) til they bottom out, then back them out a full turn, or a turn and a half. Different years models have different starting points. You'll have to look at the Bing site, or maybe Snowbum's site, for specifics. Now you've got the baseline set. Also, make sure your throttle cables at each side have roughly the same amount of play, maybe 6 - 10mm, at the place where the outer cable sheath sits in the little adjuster on the top of the carb body. Then, I like to use the shorting-stick method to get the idle where I want it (on my R90/6, around 1000rpm), and even on both sides. This is adjusted at the idle adjustment screws, not the idle mixture screws... the ones that you level-set at the beginning. (The terminology can be confusing). Once it's roughed-in like this, I use the Harmonizer from here on. But I am assuming you don't have one, so let's assume shorting sticks. One I am happy that the idle is at the right rpm and both sides are contributing equally, I will use the idle mixture screws to set each side at their highest rpm. You might have to turn one in a bit, and the other one out a bit. Turn the screw an 8th of a turn at a time, slowly, waiting to hear an increase or decrease in rpm. Or use the gauge to see the rpms rise or fall. Once you've got the idle mixture optimized on each side, go back to step one and re-balance the idle stop screws (butterfly valve) as both sides might no longer be in balance since you've optimized the idle *mixture*. You might have to keep going back and forth a few times between idle speed and idle mixture adjustments til you have them both optimized. Once you're happy with those steps, you want to adjust the throttle cable where it attaches at the carb. start the engine and twist the throttle just off idle, and adjustments to the adjusting nut until both sides are balanced *with the throttle engaged a bit*. Some people make the cable adjustments with the throttle just off idle, some recommend running it up to 3000rpm and checking. This is much easier with a gauge than with shorting sticks btw. For somebody new to it anyway. Old-timers with a lot of experience, and a good feel and good ears love the shorting sticks method. Me, my ears are shot from a lifetime of loud music so I like the Harmonizer. There's probably a lot of minor details that the gurus will pick apart here, but this is the gist. The thing is to read up and get a feel for it before you start. Just a few for starters: https://bmwmotorcycletech.info/synchcarbs.htm https://www.youtube.com/watch?v=5bmJ0iYBYgQ And this pdf from Bing to see where to set your idle-mixture screws to start: https://www.bingcarburetor.com/uploads/9/8/7/9/98794296/bmw_jetting_chart_cv_carbs.pdf Good luck. eric On 10/6/2021 3:42 PM, Zwicky, Eric wrote: > Mac is right.

Turned out there was a vestige of old hardened O-ring on one of his idle mixture screws that he didn't notice when he put new O-rings on. This prevented us from getting the idle mixture even close, and the net effect was rendering the idle stop on that side un-adjustable. But overall, it sounds like you would enjoy hanging out with a local airhead and picking up some tips. Another thing, it's a long ways off, but have you head of SuperTech weekend? It's always a fun couple of days with a wealth of great seminars, Q&As and camaraderie. I got to know a lot of good people by going to several SuperTechs. It's held in February near Reading PA.

With a strong fan and a full aux fuel tank, the entire process was maybe 10 minutes with pauses for thought. For the uninitiated (me), one tip would be to look at the throttle arm and stopping screw. For an initial setting, the screw only needs to barely touch the arm, rocking the arm will confirm a tapping sound to confirm that the screw is touching. From there, my final setting was less than one turn of the screw, inwards, on each side. Another tip- if the motor does not stall on its own by unscrewing the throttle adjuster, there is probably an air leak, confirm with starter fluid, or manually checking the hose clamps on the rubber carb tubes. >From there - the process is straightforward and mimics info available online and in video. Talking about carb tuning is like dancing about architecture. Job done, but I also know it could be done again, for there is no perfection.

Name: Resized_20211008_084601.jpeg Type: image/jpeg Size: 524028 bytes Desc: not available URL: From portergieske at me.com Fri Oct 22 12:24:35 2021 From: portergieske at me.com (Porter Gieske) Date: Fri, 22 Oct 2021 12:24:35 -0400 Subject: Trouble shooting low oil pressure Message-ID: <41E218AC-793F-491A-9A16-0B316CF8319A@me.com> Howdy folks- (1982 R100RS) Its me again, I will start out by saying that my electrical woes have been solved- with a new alternator rotor, and regulator, I am now seeing nice charging power. And, my carbs are now tuned, so thanks again for the tips and tricks there. I am trying to get to riding this moto, but I have one final issue, and that is low oil pressure, especially when the motor and oil has warmed. I have the harbor freight pressure gauge, and an m12 adapter from McMaster to make testing happen, and, I am starting the bike from cold, and seeing 40psi at 1500rpm. That lifts to 80psi at 2500rpm, and then lower values as the oil warms itself up. I am hoping for values more like 90psi to 115 when revved, that should trigger the relief valve to open. I have removed both side valve covers to inspect the oil flow at the rocker arms, I pull the plugs, ground them out on the fins and run the starter at 10 second intervals. I see small weeping on the left, less so on the right. There was plenty of oil in the covers from running it at idle. Oil level is at the max mark on the dipstick, oil is brand new. I actually have a second pressure gauge, because I didn?t trust it at first, and it reads basically the same as the HF one. I started testing oil pressure because I was getting intermittent warning lights on my dash from the oil switch, which led to me to see what the values were. What I have done: Drained the oil, replaced the oil pan gasket and cleaned off the surfaces first, checked the sump, replaced the gasket under the sump and torqued the bolts. I put the pan back on, tightening the bolts in a cross pattern, and stepping up to the torque in stages. I saw no gouges in the pan surface, and I scrubbed them clean of previous gasket material. I then moved to the oil cooler area - I pulled the filter out and inspected it - no obvious clues there, it is brand new, as are the o rings and gasket. I am using this math for the gap in the shoulder of the filter housing - average depth is 3mm, I am using the back paper gasket, which adds 0.5mm to the total depth. I am using 2 shims, each 0.3mm thick, and the O ring is of course 4mm thick. This means that the o ring is under compression. The black o ring was found to be in its groove, not pinched. I even inspected the high pressure relief valve in the back wall of the filter housing. Its a ball bearing on a spring that can get clogged or remain open. I used a sharpened wooden dowel to reach it, and I was able to depress the ball and feel it spring back into place. The last place to inspect is the breather valve. It requires the removal of the timing cover, which means all of the stuff on the front of the cover needs to be removed. Its a deep dive, not hard, but time consuming. Oil pump details - yes, I replaced the oil pump inner and outer rotor with new parts. I replaced the o ring under that cover. This model year uses machined flat surfaces on the camshaft and not a woodruff let to hold the inner rotor. Fortunately for me, Brook Reams?s videos on YouTube are perfect for me to follow, as it is the same model. The fact that I am seeing some oil pressure tells me that the oil pump itself is probably not broken nor installed incorrectly. It would be another huge task to inspect that area, as it is under the clutch assembly. I pause here for advice on anything that I might have overlooked. Any tips on recognizing oil pressure leaks is welcomed. thanks Porter From mrc.engr at verizon.net Sat Oct 23 11:45:07 2021 From: mrc.engr at verizon.net (Michael Cecchini) Date: Sat, 23 Oct 2021 15:45:07 +0000 (UTC) Subject: test References: <319986156.913527.1635003907650.ref@mail.yahoo.com> Message-ID: <319986156.913527.1635003907650@mail.yahoo.com> An HTML attachment was scrubbed...

It's a bit more expensive but has an awesome host, the Mayor of Boyertown, who makes a fantastic breakfast. And it's within walking distance of the museum.
