Tachometer Issues

Postby Porkchop Express » Sat Jun 29, 2013 7:06 pm

Hi Everyone,
For the last couple of months I've been having problems with my tachometer. I can tell the bike is idling perfectly but there are times the tach says I'm at zero rpm's when I know it's really idling at about 1,500 to 1,600. When it's reading low like this the tach needle will never go about 4,000 rpm although I might actually be revving it near redline. Today the opposite happened and it was showing it was idling at 4,000 rpm's and revving to redline even when I know the bike was actually at no more than 5,000 rpm's. This is my second instrument cluster on the SD as the first one was replaced due to a leak which caused it to stop working altogether. The replacement cluster is the 2010 version that seems pretty good at sealing out water but this tachometer issue is really annoying. I tried searching the site for similar problems forum members were reporting but I only found threads about SD's that were truly idling at the wrong rpm (in other words the tach was working fine but the engine wasn't idling properly). With mine it's the opposite, the engine is idling/performing perfectly but the tach is giving me completely bogus readings. Has any one else had an experience like this and if so what did you do to resolve it? I really don't want to have to buy a 3rd entire instrument cluster because it's obvious these things are junk and I hate to spend money on something I know will break again in a year or so.

Thanks in advance for your help.

I had that happen to me during a track day. The speedo and rpm went nuts. Sometimes showing 4K rpm while idling. Ended up being a loose connection inside the nose mask. Right side as you are sitting on the bike.
