speedometer

I just installed a electronic speedometer on my bike, however when I start my 80cc engine the speedometer quits working, kill engine speedometer works. I know it must have something to do with ignition. Is there anything that can be done so I can use my speedometer?

well, the speedo's work with magnetic pickups.. as the magnet passes the pickup, a small voltage is induced.. if your getting feedback from the engine into the pickup.. try mounting the pickup on a small peice of rubber to isolate it... could also be getting induction from the plug wire, in which case the plug wire has a bad case, or the speedo wire runs close to it... attached to front wheel or back wheel?

I could never get my wireless speedo to work with the engine. But to make a wired one work you should only need a higher quality, magnetically shielded, spark plug wire.

You can get them at your local auto parts store, or you could order one from SBP.

radio suppression plug wire is all it is.

I tried the Ferrite suppression sleeve, running the speedo pick-up wire through it with no luck. I'll try a new suppression plug wire next. Ohhhh I just got my California Lic plate from the DMV today. I have a M1 lic. so I guess I'm legal now.
