As far as overall quality, I'd say the set of valve covers is very well made. It does brighten up the engine a bit and add a bit of character.
Functionally wise, the fit is prim, very snug and the gaskets swap right over though I do recommend buying new gaskets for older bikes like mine.
I am curious to see what the temp differences will be, with both using a thermal and laser reading to check. I'm sure the added heat dispersion from this and perhaps a spal fan would add up and help tremendously. Which will be my next purchase.
Hope to see more from shotcraft for mine and others bikes. Thanks again guys!
