I was wondering how big the tach hole on the non baja bikes are that you have to cut out, im think of maybe butting in a oil pressure gauge there and not a tach, i know i can go with a smaller size and not fill up the whole area, but i was wondering what size of hole it was to fill the whole area up

 

The only thing I can say is that the tach fills in that hole where it says "Bombardier". So if you measure that it should be pretty close.

 

i guess i could of done that

 

ita a 3" hole
