Only breakdown I ever had with my R-90/6, in 13 years of ownership, was when the aftermarket electronic ignition system randomly cooked itself out on the road. I trailered the disabled bike home, immediately pulled-off the electronic ignition system, reinstalled the original OEM breaker points --and never again had a problem. Sometimes (often) simplicity is the superior approach.
Yeah. There are a fair bit of suspect options out there. This was all on me though. This is one of three bikes in my garage and all the modernization is an experiemnt, so I will continue for now.
Regulators are a weak point in nearly ever make of bike except Yamaha, the battery sulfates in little time causing regulators to overheat, some have no heat sink or airflow.
Yeah. It was really odd to lose both at the same time, more or less. That had me going back over the electrical system a few times to be sure it wasn't something else. In the end, one was a failed solonoid and the other was a mechanical error. It just let's me know how long those grub screws would last by just being "as tight as I was comfortable with." It's had no issues since then, but I am pretty sure I would not use this style of ignition system again as the grub screws will be a worry over time.
What a great motor on those and the windscreen is just right.
Thanks! It was a great experience building it.

Very strange and unfortunate to have those two rare failures at the same time! Now I'm trying to remember if I locktighted those little set screws...
