I say yes.. unless you’re one of the few Harley V-Twins against the metrics. The bikes are NOT equal. Back half MPH gain is everything. If we could run a 9.6@150….. lights out

This….

When I run them in the 1/8 I have a way better chance.

I used a timer and air solenoid. Might not need it if you don’t hold the throttle
wide open. Not sure.

That was a no go as well. Need to use a N.O. solenoid activated by the clutch switch. The lectron draws fuel to the main way faster than the E did. The wego showed afr below 10.4 on both hits, with wfo bog lasting for .5ish sec and pto bog lasting .2ish.
