Hello
I recently had some problems with my tach. Thought I was topping out at 3800-4000RPM but after re wrapping the wire I am getting 7-8000RPM readings. That tach would turn off and reset all the time so I took it off and replaced it with a different unit. On the original unit I wrapped it around the plug wire 5 times like was recommended.
New unit is reading closer to the high readings of the old one but it raises the question:
The wraps apparently influence the readings, so how to know what is accurate and how many wraps?
Obviously the bike wasn’t topping out at 3900RPM, but is it really turning 8000RPM?
I have some TAV parts coming so I want to get those in first, but supposed to engage at 2800 but now engages at 3800-4000
Do I use the engagement of the TAV to set the tach?
Thanks for any advice
