I must add that the bike goes like a raped ape.

Looks good Pablo.

re: port job
did you do any reshaping and height matching or just clean up the casting marks?

porting is fun.

I totally reshaped to match. The factory "match" is a total joke....

did you match the gasket or cylinder port heights?

Since I made my own gaskets everything matches on the intake an exhaust sides. Interestingly the ports themselves are plenty "big". The intake I left a little rough, the exhaust is very smooth. Most material removal was in the manifolds themselves. The exhaust shape bore no resemblance. The intake had choke points.

The hardest part was cutting the exhaust gasket.

There is still more porting fun to be had!

The exhaust and intake ports should be at the same height so that as the piston passes by they open at the same time. ugly castings like you describe usually aren't even close. you can measure it by installing the piston and shining a light through the ports. both ports should be even with respect to the piston.
If you are daring, you can "raise" the port height making the top of the port closer to the head. that is sort of like advancing cam timing.
the problem with any porting is once the material is gone there is no going back.

Maybe next go around - seems like plenty of zip now!!
