Brand new out of the box predator 212 supposedly the newest model non hemi. Most things resemble the older version but with some differences that I'm finding. Biggest issue being I bought a rev kit from nr-racing and things don't go together correctly, way too much lash. The kit came with one copper ring shim one lash cap and one spring retainer that is supposed to slide onto the valve and of course the two springs. The directions state copper shim not used on the 212 predators. You will re-use your stock exhaust retainer and lash cap. The supplied retainer and lash cap go on the intake valve.
My problem the valves are both the same length so agree no lower shim needed. But the stock engine doesn't have the slide off retainers or any lash caps. It has a standard retainer with the small split locks. The supplied retainer wont fit the valve groove so no use there and the lash cap seems too tall. It also appears that if I just adjust the rockers down they may not hit correctly. This predator also has a vented stamped valve cover and a plastic insert into the fuel tank both vent into the air box.
Sorry for such a long post I've been searching for hours and cant find any info with this style that is a non hemi.
