I want to change my speedo??
how hard is it to change my 85 mph speedo to a 140+ speedo?? What do you need to change? IS it easier to just buy one and put it in sepaerate and just have two? And, how long does it take?? Thanks

Not hard at all, all you have to do is buy a 145 speedo and put it in. You can get them off ebay for around $60
