Does anyone happen to know what the ratio is for the tachometer on an 82 Nighthawk 450? I need to replace mine and I found an aftermarket one on EBay that comes with a matching speedo that looks good. May need to replace speedo as well. I Just replaced the cable but the speedo is sticking. Can find replacement stock speedo on eBay but sadly no tach at the moment. The ratio on the tach is 1:5 and the speedo is 60mph @ 2240 rpm. I know the Yamaha’s and Kawasaki’s use a 1:5 ratio but not sure about the Honda’s. Would these work for my Honda? Thanks.
Hmmm. That’s a good question Matt.
I didn’t find the answer in my manuals. I’ll have to pass this one off to the readers. Anyone know?
