Re: R75/6 LED turn signals. Dash light won’t flash
They (diodes) aren't rated in watts and you can't infer a wattage by multiplying amps by volts since the two ratings refer to different conditions. That's why I asked what specific diode you (Rob) would recommend for this application. The few times I've needed diodes for a project, I would simply e...

Re: R75/6 LED turn signals. Dash light won’t flash
Thank you both for the reply. Rob, i think you are right, the relay is for LEDs and has a 4 prong set up but the 4th prong is labeled “sense” which I thought was for the dash warning light but it appears to be a “bulb out” sensing feature. I haven't seen a conversion to LED turn signal bulbs that a...

Re: R75/6 LED turn signals. Dash light won’t flash
Do you want a cheap and easy fix to circumvent the problem? Power the dash indicator bulb directly from the flasher hot leads. You’ll need two 1W diodes so the left side doesn’t power the right side and vice-versa. This minor surgery can easily be done from inside the headlight. You can get the diod...

Re: Spark plug shorting method for carb sync with EME digital ignition system
On proper electronic ignition with coils of low primary resistance the joules stored in the coil will be at least 4 times greater than for points coils making the HT current at least 4 times higher on a dead short so there is much more potential to do damage. Hmmm..Your point seems a valid but.. Is...

Re: Spark plug shorting method for carb sync with EME digital ignition system
Answer to your question: If the HT wire is grounded, or connected to a grounded spark plug, you won’t harm the ignition.
For the record, the shorting method is not the best way to set up your carbs, but if it works for you, go for it.

Re: Odometer rolled over again
Almost 22,000km on the SpeedHut GPS speedometer since may. Smooth, steady and very accurate. The compass function is a real bonus. For some unknown reason it resets itself occasionally, this takes about five seconds, and then everything's fine again. There is no pattern to this occurrence and it is ...

Re: Sticking / Dragging Front Brembo Brakes
If the brake releases instantly when you open a caliper bleeder, the return hole in the master cylinder is blocked. Replacing the seals in the master cylinder(s) and caliper(s) on any forty year old vehicle is a not a bad idea even if everything is working well. EME has all the parts you'll need. Ex...

Re: R100t first gear jump
Roger, If you’re not ready for a transmission rebuild for whatever reason, change the transmission oil (when hot) and see what comes out. If no chunks fall out and there’s no crap on the magnetic drain plug you can probably get many thousands of miles of riding out of it if you ‘adjust’ your riding ...

Re: R100t first gear jump
If it was a driveshaft/clutch/spline issue, it would also do it in second gear when similar torque is applied. You have an internal transmission issue. (99.999% probability) I've fixed this problem more than once on customer bikes. Coincidentally they were all very high mileage bikes. It’s impossibl...
