Thanks guys for the info .great pics!Irv,I'll give that shop a call this weekend. Sounds like the perfect spot and alot closer than Royal.thanks I'll pass on your message. starky, I have almost always had a tach on my machines,boats, sleds trucks, bikes and I feel that it is easier to understand how well the machine is running by comparing rpm to speed ,or excelleration ,or idle, or rpm's during warm up or to engine performance before and after a mod has been done. I guess it's just a another way of better understanding the machine.
