I'm having issues with my "meter" working correctly on my 2004 Honda Foreman. ATV has been stored 100% inside and probably has approx 3000 miles on it. Issues first started with the odometer not being correct (jumped to some crazy number). Then, the speed starting reading incorrect (approx double) and the gear does not display at all. Is this repairable? 1996Phazer!
