amber brown is a good color for a plug, and 88 main jet is good for a 47mm (80cc) big bore kit with an exhaust and air filter

There are some nice and cheap add on tach's. I added a Tiny Tach, about $50.00, but there is a lower cost one that works well, from feed back from guys that added them.

Yeah I was looking at the trail tach. Correct me if I'm wrong but all I gotta do is mount it and wrap that wire around my coil a few times right?
