RPM,s

[MotorMac]

Reading thru many posts past and present I read things like "my engine revs to 6500 rpm" other posts say" "at 3000 rpm my bike begins to sputter" these are just a couple of examples of many similar posts..Now my question is how are these guys measuring their RPMs? If they are using a tachometer how is it hooked up? will attaching a tach to the blue wire give you rpm readings?

they have a wire attached to the spark plug wire.

HI,

My Dax 70 will pull to 6400 RPM and maybe more but I don't push it that far because at 6400 it sounds "rattly" ...I run a Sen Dec Fastach ....pickup is a wire wrapped around the plug wire.

Hope this helps you.

Im working on converting a digital speedo into a tach. I'm about half way there, using a $10 Schwinn speedo from Walmart. I expect it will require just the speedo and very few other components. I'll post a design thread once it's done and working.
