Rev tacho, speedo?

[DustyFork]

I'm looking to get a digital rev tacho and maybe speedo. Looking on the net but not sure which one to get. Need it to tune the bike. dont know what rev range my motor revs to either!! I have a yx 160 and I think it revs to 9500 from a little research but not sure, any one know? And any one know where to get a cheap tacho from?

get a TTO tach/hour meter for the rpms and good to keep track of riding hours
