so i picked up the nav today after 2 weeks at the mechanix,
turns out the head was cracked through the cam journal.
so new head, bolts and gaskets, radiator clean and repair, new injectors.
all up came to $4600.
also got them to fit up my calmini uca's. looks like ive got at least 30mm maybe more bumpstop clearance now. felt pretty good on the ride home.
