Couldn’t wait, went into the man-cave and cranked it a couple of times - no bubbles. What a strange machine, I am running out of ideas.

I will go ahead and speculate on some trouble shooting after all that has been tried and discussed. It sounds like it is getting fuel as the spark plug has been described as wet and no water was present when the exhaust was removed. And I am assuming it has enough compression to run. ( was a compression test done ) My suggestion is to get a new cheap spark plug that will fit the cap and remove the ground electrode strap from the spark plug creating a very wide gap. A new plug is best as deposits on the center electrode porcelain can become a conductor with less resistance than jumping the widened gap. Compression pressure raises the resistance to the spark jumping the gap. If cranking the engine while observing the plug with the widened gap there is no spark then I would suspect it has to weak of a spark to start and run. Possible bad CDI box is most likely or a bad coil maybe. If it does have spark with the wide gap then it may just be a fouled spark plug from deposits on the center electrode porcelain. I would say a NEW plug is the next thing to try. Stuart ( t140v is a member of this board ) makes an adapter to run a readily available plug. Good luck and let us know what you find.

Hallo Zebulon!
Vielleicht kannst du mich ja mal anrufen. Ich bin in Bad Kreuznach (Rheinland-Pfalz) zu Hause und restauriere zur Zeit auch eine RE 5 (M), die 30 Jahre gestanden hat. Bei mir hat es auch lange gedauert, bis die Mühle die ersten Töne von sich gegeben hat. 0671 65220

It does't even start with brake cleaner, spark travelt when I manipulatetd on old plug to a wide gab. Compression with a traditional tester (non-wankel) shows around 120 psi, but had only 1 maybe 1 1/2 thread, sealed it as good as i could. Bike has the adapter and I have two NGK LMAR9E-J, both have around 4,6kOhm. One old, one i bought when this odyssee started There is not much left.
Is there a replacement for the ignition available?

Replacement ignition? Not readily. The CDI units can be repaired and/or upgraded. We have had electronic ignitions available at some points but no one is producing them on a regular basis.
If you're confident with electronics, I can send you a plan for a replacement CDI to build yourself.

Yes please, eigher I do it or I will find someone.
There are used ones listed, not sure if I try.

Hi Zebulon: Does your CDI unit make the high pitched squeal noise? From the cdi-repair-alternatives link that Wayne provided, it seems like the intensity of the sound is correlated to the strength of the spark. (I have never seen anyone else's RE5 aside from mine so unfortunately I don't know how much the sound varies between two healthy units or a healthy and damaged unit) Also, has your CDI's circuit board been potted with adhesive compound? I really like the GT750 "emergency" coil that Hudson put together. That might be a quick way to determine if your problem is your CDI unit or not.
I wish you luck on your troubleshooting odyssey!

Hi Al and all, the noise it there, I am in contact with a company, that maybe has a solution for a replacement. I have other bikes with their units. Have not opened mine.
As the engine did not respond to brake cleaner and anything else I did for the last weeks, I cleaned the carb again, just because I thought I had to do something, reassemble everything and wait for a miracle and/or inspiration….or a new ignition. I looked at every jet again and got the SPJ out this time, they all looked good, 20 minutes at 80°C ultrasonic just the carb housing Couldn’t resist to crank it, WTF… it started! I wasn’t prepared, run out of fuel on the external tank, kept the momentum and hoped it was not a one off, installed the tank and it started again! I have no clue why it suddenly ran, the SPJ doesn't seem to be related to the starting circuit, was anything left under the jet or somewhere else? I didn’t do things different than before, except removing the two thin gaskets of the manifold/carb thick gaskets, because they got ripped after taking them on and off so many times.
After all it’s “just” carb related an the mixture has to be spot on, probably I sprayed too much brake cleaner into the manifold.
I had to stop it after a couple of minutes as one of the oil cooler lines got leaky. Ordered a couple of custom-made lines today and hope that I am able to do a real road test next weekend if weather permits and- IF ITS STARTS AGAIN.

I am cautiously optimistic regarding my starting issue; I did two short test drives 7 and 28 miles and she always started up without choke even when engine is cold. Surprised by this wonderful handling I noticed a noisy speedo and an engine that revs up very slowly. Seems like another common problem, so I am currently reading all related posts. However, I realized I can overcome this by using its mid-range torque, that will bring me over this season, as I don’t want to mess with the carb again, at least not now. I am pleased with the replacement oil lines. Speaking of oil, I need to check how high the consumption will be, on the first short drive I was concerned, but drive was way too short, it looked better on the second run. Now I need to get it registered for road use. I found a replacement CDI made in Germany for oldtimer braker point ignitions. The guy claimed that, it was fitted to a RE5 before. It needs a different coil though. I will order that as a spare.

Glad that you got it running this weekend and were able to take it for a ride! It is a wonderful handing bike for the highway. Beautiful photo of your bike. The orange paint looks superb in the sunlight.
Not sure why your engine revs up slowly though. Perhaps its an uneven transition from primary to secondary or perhaps a partial blockage in the vacuum line to the secondary butterfly vacuum motor? I'm not sure.
Metering oil consumption is slow. As long as it is half full you can make many short test runs without worrying that it will empty during the ride. The metering oil lamp gives you adequate warning.
Yes, it seems that the RE5 coil is not set up for old time breaker ignition duty. It seems that the GT750 type coil is suitable for that type of use.
What rear tire are you using?
Al

Thanks, it's such a weight off my mind!
I thought about sump oil.

Congratulations Zebulon and well done for sticking with it. It would have been frustrating but many of us have experienced that.
Re your sump oil consumption- They can burn lots of oil after a long lay up. One of my bikes used about 1 litre in the first 1000 klm and then it settled down to hardly any.
Keep an eye on it for sure, Suzuki considered up to ~600cc of sump oil per 1000klm within "normal" range but I would consider this to be very high. "Normal" use in my opinion is a fraction of this.

Speedo noises are not common, try lubing the cable with axle grease but wipe the top 6-8 inches to prevent creep into the face.

Luckily, I could fix that with Sonax SX90 and proper cable routing. The rod of the secondary butterfly vacuum actuator was not connected to the lever. Fun to drive BUT the sump oil consumption is wayyy up from the recommended value. I don't know how long this bike has been sat around, but I will drive it only a couple of times a year and that will probably not "massage" the seals enough. Anyone who has used Wynn's oil leak stop or something similar to speed up the process?
