The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.
I am looking to fit an aftermarket mechanical speedo to my fightered Ace and I am not sure which ratio I need. There are several that are 1:1, 2:1 and some that say 60 mph:2240 RPM and 2:1:1.
After alot of unsuccessful dicking around with digital speedos i just want a simple analog speedo that will work with the existing speedo drive.
