...Anything below that rpm caused the engine to flood instantly if the throttle was more than just slightly open, due to the multiple blowback gas passage past the jets.

Pé,

Tuned length runners work great with port fuel injection, like in many cars.

This is because those multiple reverberations don't affect the mixture strength, with the fixed amount of fuel injected at the port.

Any power boost will only happen at the various harmonic RPM values, but the mixture will not be affected.

The [link=http://www.bgsoflex.com/intakeln.html]software for the calculation of the intake runner length[/link] assumes the runners precede the point of injection. It is also designed for four-stroke engines, so the RPM numbers must be halved...
