Crank scrapers or plate...?

If you have other reasons to use them, then I am all ears, particularly on the aspects of how stroke and displacement impact the usefulness of scrapers. So hit those notes! I have read the IJ site BTW, so that good has come of this.

Everything is has a cost/benefit aspect, and knowing what the results are is worth the conversation IMO. It is $80 for the cheapest IJ scraper set for the SBM, and they have pricier ones. But, how many HP and other benefits will be gained in the application versus that cost? Is it 1 HP for cruising at 3,000 RPM, or 10 HP? That answer makes a BIG difference; that cost/benefit needs to be balanced by everyone to their own satisfaction; IMHO, it is more helpful to just give people the facts, point out the good and the bad, and let them decide, and avoid judgments on the individual decisions.
