I think the HP you guys are giving out on ported engines needs someone to tune it right,
I personally think your numbers are to low,I hoep im not expecting to much.
Once I get some milage on the engine,I willahve it jetted and tuned right.

Its not who built your engine,its who has tuned it.You can have the best built engine out there,if its not tuned properly then you wont get the expected HP.
J or Monster Port
The J ported engine (also known as monster port) is as big as conventional side-plate porting can go. It is the same as the bridge port in design, but the bridged port is now fatter and extends past the face of the rotor and into the housing’s water seal / O-ring requiring the need for the seal to be cut back and filled with a metal type sealant such as "Devcon", plus, depending on the side plate used, the water gallery requires blocking off and filling on the side plate and the rotor matching.
Cutting into the rotor housing is also needed for port matching. The main problem with this design of port is a short life-span as water does and will seep through the seals. The main field where a J-port is likely to be seen is on the track where restrictions don't allow peripheral porting, or a slightly wider power band is desired. Typically around 300hp can be expected
