Ok a friend of mine brought his 09 SP500 with a weird problem, when it idles the RPM reads zero but when you rev it works ok. :wtf: I told him that I will take a look at it just because the problem sounded interesting.

Does anybody has any idea of what might be wrong with it?

Hmm, that is weird. Is it EFI or carbed? Do any of the other speedo functions act funny? Only suggestion I'd have is to check all connections and grounds. If its EFI, run through all the diagnostics and see if anything else acts up. If so, it may be the speedo itself.

I will take a look at it later on but I believe it has a carb.
