i did not realize that so thanks for the info. this engine and these do not have harmonic balancers but later models did get them. not sure what year. planned on the rods and pistons. i figured i would have the crank with the flywheel balanced but maybe just the flywheel now.
laying the shock inline with the axle as in from wheel to center of frame rather than forward like it was as in from wheel to back of seat. i have enough room just need to see how it will lay out.
Yes,in line with axles. Try to hit perpendicular with axle at full bump.
so here are some pics of the head. stock spare head first then the head i ported/polished so you can kind of see what i did. i know pics aren't the same as in person but..... now i didn't take any real material off the short side in the intake or exh runners just cleaned all the slag and polished the wall as best as i could. not a lot of material in those spots and read many posts that they can crack easy if you take much. i did go to town in the bowl area and the slag was bad in there. cleaned and took a little out of the cc as well. funny thing is it looks a lot smoother in person but the camera really picks up the marks. so fabbr you've done a few heads so good or bad ...thoughts?
Believe it or not,a rough intake port will outflow a polished intake port,all things equal otherwise. a polished port will actually grab onto the airflow and reduce it to near zero ,or at least dramatically slower ,close to the port walls. That in turn tries to slow the overall port flow. A coarse ground surface or an as machined in the case of a cnc ported head will easily outflow a polished one. The opposite is true of the exhaust. Doesn't really hurt flow polishing the ex port but it does little to enhance it either.
