Open Rockers
Hey all! I just picked up a Saito FA-30 open rocker engine. It was pretty gunked up but I cleaned it and is now purring nicely. I have a couple questions. First I understand that the letter marking on the mounting lug indicates it's date. Mine has a B. Any ideas of age on this? Also it has a pressure nipple on both the header pipe and muffler. It came with the crankcase pressure bleed hooked to the header. That doesn't seem right. Shouldn't the crank vent to air? Unless the crank puts out enough pressure to overcome the exhaust pressure.
