Re: 100:1 Mix
I agree with gearnut. With my new motors I just do the normal to increase air flow port matching and better air filter the adjust the e-clip to the leanest setting which is still rich with the opti, but leave it there for break in. Then after break in I really tune it. I also run it pretty hard during break-in so the extra richness helps protect it a little.
Work hard, Play harder and enjoy the Ride!!!!
