I have been reasonably happy with the RB mod on my '05. Not earth shaking like the head mod but it cleaned things up a bit and made me the Dead -Engine Start King.
Is this new release the "3rd Gen" or is the Gen2 in the cast version?
What other problems does he ned to address? Cable? Off-Idle? Metering Rod?
When folks say they are 90% happy with the APT SCarb, is it because they have raised the bar so high? Were they only 80% happy with the RB modded carb? Is the Lectron getting sorted out ?
