My 1982 Yamaha Maxim 1100 is supposedly capable of 130+mph, but it was built in an era of 85mph speedometers. While I have never actually ridden it faster than 70 or so, I find it irritating that the speedo runs out of meter-face at 2/3 of the machine's potential speed. Anyone know of an aftermarket supplier of speedometers that will fit into original equipment nacelles? Thanks in advance for the help! Chuck Rogers @ ATT-ISL, Denver

The elegant solution for this is a meter face for the center part of your tachometer that is calibrated in top-gear MPH or KPH. I don't remember product names off hand, but you could easily fabricate your own. While you're at it, you could do concentric calibrations for 4th gear, and even 3rd, if you plan to exceed 85MPH. Next, the inclinometer for wheelie-ing on full dressers. Harvey S. Cohen, mtuxo!hsc

Get the glass off the speedo either by prying or disassembly and snip off the pin that stops the needle going past 85. You can then paint on more numbers and stick another pin on further round the dial. They suggested paper stick-on digits, but white-out would probably work just as well. I ride a Honda CB750F and have the same problem (85mph speedo). I haven't gotten around to this mod yet, but someday... patrick {ihnp4, hplabs, amdcad, ucbvax!dual}!fortune!stirling

If the speedometer uses a spiral or coil return spring to counter- balance the cable-generated force moving the needle, then the reading may not be linear at the extreme end of the needle movement. [Of course, if accuracy was really important, you could get someone to perch up on your handlebars with a bottle of white-out and mark the new speed indications as you increase speed from 85mph to 130+mph. :-) My officemate has volunteered to perform this service, should you wish to try this out.] Actually, you could do the same thing with a power drill attached to the speedo cable. However, before you start tearing up your speedometer, wait a few days: A friend of mine has found an advertisement in an old "Rider" magazine which purports to provide accurate OEM speedometer guts with new meter faces for popular models. If it pans out, I'll post it. Again, thanks for the help, Chuck Rogers @ ATT-ISL, Denver
