Hi you all,
I'm wondering if any of you done port flowing and head flattening.
I could try to find a couple of busted cylinder heads and cut them in half to get an idea of the "flesh" between the ports and water but if anyone has done this before I can spare myself the trouble.
Also if any of you played with flattening the head, it would be nice to hear the ideal compression ratio increase.
I'm rebuilding my K100 with K1100 TB's, still have to adjust the AFS (Bike is in pieces right now…), K&N box filter, semi open exhaust and standard injectors (also have the K1100 injectors) and the ignition advancement of course.
Planning to attend Belgian classic TT races so I want to keep the tech as close to the early 80's as possible.
Any input is welcome!
P.s.: Read that some AFS's don't like the oil coming from aftermarket filters, anyone experience with this using the L-jet AFS?
