    I tried the hotcam shims as advised and they are very accurately made with the exact same precision as the stock shims. They are clearly marked for thickness, better marking than the stock shims because it shows the actual size and not just the last 2 digits.

    I ordered the refill kits since I needed to increase the clearance using ferra valves and APE springs/retainers.

    Fits like OEM!

    I set mine at (I).20 and (E) .30mm. I'm thinking by going loose on the spec will last the longest time between intervals.

    The job kinda sucks, no timing marks on the drive coupler and the tensioner is buried. I just marked the thing myself.

    Why they didn't go with hydraulic lifters like others is beyond me. The engine is relatively low reving too so they could have installed the shims on top of the buckets like say some motorcycles. This would mean no camshaft removal.

    you would want to run tighter specs to keep from changing it more often, not looser, tighter would also give you a little more lift than loose... maybe im confused...
