We all pay some really big and dumb prices for a variety of parts for our bikes, I know that. And we absolutely need the vendors and inventors, so we can make personal statements about our bikes. God bless them all. And I really mean that. But I'll be damn if I'm going to pay half a grand ($500) for a tach. Particularly one that probably costs less than 50 bucks. I know all about R&D, but $500! I use the Cyclecraft tach on my "C" and have been very happy with it. Now I need one for my Retro with the Autometer tach and I'm told it costs $500!!! Ever since I heard that, I have a picture in my mind of a distant voice calling.....Hey Stupid!! But this time I refuse to answer. Now, if some one can supply me with the Autometer tach number (I'm gonna find it anyway) I will make a simple bracket of 1/4" aluminum, bend and shape it, have it chromed, make it attachable to the back side of the existing handle bar clamp and probably want have more than $150 in it. For sure someone's gonna come back with a reply that it can't be done for this or that reason. But I use to do minor fabrication on my race cars and I've stared at the clamp on my Retro for an hour. It's doable. And i'll post the results when finished. Now who's got that number or do I have to call Autometer in the morning.
