Tell us a little about you. What cars you are interested, where you are from and why you are interested in learning to tune.
Howdy - its Don here from an island off the West Coast of Canada. My interest is 2 stroke off road motorcycles. I have two 2-stroke EFI bikes from OSSA and KTM, and another I am planning to convert.
Glad this forum is here, getting the right technical EFI help from the dirt bike forums is a challenge.
