I just finished installing new 98” big bore kit and rebuilt and replaced every single component in this engine other then flywheel. New oil pump, cam plate, throttle body, exhaust, Trinny, clutch, compensator, I mean everything. I switched cams to the woods tw-8g cams. Gear drive. S&s pushrods and premium s&s lifters. Everything. Heads ported, the rocker box had clearance but we even grinded more out to make sure. So now I still have a really loud clacking on the top end. I have only been able to ride this 20 miles. So the break in is not even complete. Could one of these lifters actually be making this much noise. Here is a 30 sec. video maybe one of you guys can help.
thanks
