Frankly, the whole mechanically driven speedo thing is unnecessary.
Sure, electronic speed sensors can be problematic, but there are very good ones available that run on multiple rare earth magnet pulses past a pickup as the wheel rotates. Even better, the good ones are fully programmable to accomodate varying wheel sizes. Digital tachs are readily available as well.
Oh I'm sure there are indeed well-made models available. I'm basing my avoidance of digital systems on the love of simplicity. When you get to the point of computerizing everything you've reached a point where repair is impossible without some very exact specific knowledge and a fortune spent in diagnostic equipment. For the average guy it comes down to "parts chuckin" to "fix" anything and by it's very nature that is so wasteful as to be obscene.
thanks for the help guys... for the longest I was using a bicycle speedo until our dog ate it and I learned what rpm at what gear was the speed I wanted ... damn bmw speedos quit working(known issue) cant tell if its the unit, crown gear or cable.... and no real way of testing.
the only thing in the cluster I really need is the tach otherwise If I can find a way to get rid of all of it I would
Silly question but does the bike make enough noise so that you could know when to shift by ear? Most folks I know using manual shift (cars & bikes) just develop a knack for it and don't really need a tach all that much. Remembering to count your gears as you shift is important as well. I was always taught to not depend on the idiot lights but I will admit they can be handy sometimes. Having a bike quit on you and then forgetting what gear it's in when you try and restart it is at the least embarrassing and can be a recipe for fucking shit up.
since the mod exhaust yes... I know when to shift... I use tach for the speed judgement... pretty good at telling what rpms im at by sound but the diff between 3000 and 3250 is a speeding ticket... I need to look it up but im wondering if I terminate the pin for whatever is keeping it from starting if it would start
