I have finally finished my electrical mods with the coil relay and replacement of the R/R unit and took the bike out for a test ride. It was running really well and my initial ride around the neighborhood turned into a 40 mile ride...
The only thing that was off a bit was the tachometer reading. It was fine at idle and lower speeds as well as all of the times in the shed that I was checking electrical readings at 5,000 RPM. I had replaced the cable early in my rebuild process since the original cable had the end snapped off. The tach cable connects to the valve cover and I used an OEM head gasket.
On the road with acceleration the tach needle was initially very jumpy, 1,000 RPM jumps, up into the 7-8,000 rpm range while the engine was accelerating smoothly. Less jumpy as time went on, but then never really increased outside of the 5,000 range. I was winding it out pretty well, so not sure why the readings aren't keeping up.
Any ideas on where I should look to improve the tach readings?
Thanks,
Dave
