Shim under/Shimless buckets for MZ/VZ possible?

[singleslammer]

I may have missed this but what is the advantage of shimless buckets?

[Toysrme]

almost impercievalbe reciprocating weight reduction.


the big thing is that since the shim is under the bucket, when using custom cam profiles (especially when using re-ground cams that require making up alot of distance via the shims). the aggressive cam lobe won't hit the shim ontop of the bucket & knock it off. which can happen.
so the high revving shim/bucket combo's put the shim under the bucket.

Yea toys got it pretty much....shimless is what i will be using on my higher rpm n/a builds as i will compensate for clearances issues by using longer tip valves which i have.

well considering thats what my new goals seem to be panning out to be, that is VERY helpful info
