marktheaxeman Posted September 15, 2020 Share Posted September 15, 2020 Last time I was out on the bike I noticed that the rev counter was reading very low - probably around 1500-2500 lower than the actual revs. Weirdly though when I really revved the bike over say 5000 it seemed to read more accurately. At tick over the needle was barely moving. Anyone know what is going on please. I was going to start checking connections but not sure where to start. Many thanks...

docc Posted September 15, 2020 Share Posted September 15, 2020 The tach is fed through relay #2 (from the front). Make sure those contacts are clean and consider installing a full set of “Best Relays” . . . ( OMRON G8HE ) 2 Link to comment Share on other sites More sharing options...
LowRyter Posted September 16, 2020 Share Posted September 16, 2020 if it rattles, then the counterweight came off and needs to be epoxied on. If it doesn't rattle, then check out other suggestions here. After that, get it fixed. https://joellevinecompany.com/speedo-tach-repair/ 1 Link to comment Share on other sites More sharing options...
