I couldn't find any 600 ohm caps, So I ordered a set of 5K ohms ones.

The NGK caps are all 5000 ohms

The manual states the HT leads are to be 600 ohms radio suppression types I believe these should work https://www.gsparkplug.com/1x-ngk-resistor-spark-plug-cap-sd05eg-10-12mm-nut-terminal-black.html?fbclid=IwY2xjawMG04NleHRuA2FlbQIxMABicmlkETFaUHNiTzlFMFpaTzNGSVh0AR5iJqeap1e4wjni5jjoZ74wj_mMOYA6C_9a...

Looking for a good set of spark plug wires for a stock Classic. Do they need to be a resistor type?

What are the differences between a single rotor idle , and dual rotor idle?

I do not need one now, but keep up the good work, as I might down the road

I changed the transmission oil on my Classic from 85/140 to the Redline 75/250 and the rattly noises on deceleration almost completely went away, I am calling it a success.

Does anyone have any more updates on the Red Line 250w gear oil?

speedo reads 60mph at 2700rpm in 5th gear.(if the tach is correct )

Is there a way to calibrate a Motometer speedo to read accurate?

The repaired tach did not read correctly when the bike was running. The rebuilder did not set it up take a signal from the coil. I sent it back to him to correct it . The last communication I had with him was 3/25/2025 shown below : After that nothing , no call returns, emails, the tach is lost. I f...

With my Classic with oem wiring I simply pulled the red/black wire out of the plug going into the stock ignition , allowing the side stand switch to turn on the ss light but not kil the ignition.

Hi James, no the socket is under the left hand side panel. I have been trying to upload a photo but it repeatable says the file size is too large, am I missing something? Regards Roy you have to reduce the image size, either from your camera or a graphics program , send it to me through the email a...

#6---- Are you referring the twin plug for the side stand switch? Mine was forced backwards, I changed it to be correct, but never thought it was an issue either way.

I have received the repaired tach. So far so good, I have not run the bike yet, but the tach is reading zero when the key is turned on.

I am not confident that my tach will be fixed. However I received a few back issues of Epitrochoid and by chance there was a discussion printed of the tachs used on air cooler rotaries. It appears to be saying the tach AN is selling would work as a replacement. https://andover-rotary.co.uk/rt/shop-d...

Thanks for the response, I have found someone in the states to repair it, as I believe I have isolated the problem to the tach itself, also the speedo trip odometer reset does not work. The person repairing the tach believes he has found a solution smiley , , I will let everyone know, the outcome

Here is his bike

I disconnected the black/white trigger wire from the tach, reinstalled the binnacle, turned on the key and the tach still goes to 10k, which tells me its in the tach, I found someone that will rebuild/repair it here in the states, so more to come DSC04710 my tach underside.jpg Here's something very...

Hi James, Re:the speedo trip metre, The one on my Classic stopped working very early in the bikes life,almost impossible to repair(so I was informed at the time)finances at the time were a bit limited so I managed to live without a trip metre wink, I got so used to not having one that I never did b...

Also the tach still reads 10k while running

thanks for responding, I have sent you an email, again thank you very much

Can I replace my tach with this one from Andover Norton? They do not know. the backs are different

one clue that will not go away is the tach malfunction, with the key on, I unplugged each connector in the wiring harness one by one. It did not change with all the connectors unplugged, so it has to be the tach or the binnacle wiring, visibly it seemed good.

Does the Classic share its dash and indicator lights with any other rotaries? I could use a better one.

The tach on my Classic goes to 10000rpm and stays there when the ignition is switched on (not started). Where should I start to look when trouble shooting?
