will be interesting to see the dyno graph....ive tuned my barrel exactly the same with the casing port and using v force reeds/dev tour pipe with a 35mikuni...i havnt done the transfers or the secondary boost...i get 23hp with 18lb of torque....not up there on the hp hit parade but it rides lovlely so im not too concerned

As you'll be aware, the bottom ring of the MB piston presents issues on that side with its peg position, but i came up with a suitable solution.

How are you routing the additional boost ports on your 7 port motors?

The seven port motors are tuned by Darrell, so unfortunately I can't comment on how Darrell has done it.
Wot are the reasons for the Extra port in the crank case/inlet, wot piston would you run with that modification, one with windows or no windows but a cut out instead.

Wot piston configuration have you found works best?
