There is one flavor that you can add either to the crankcase (oil) to remove gunk from the internals or to the gas to clean the fuel system.

The other product, a spray foam and a video below on using the spray foam to clean motor top end. I did not use this product, I used the tank additive but I have heard a lot of anecdotal positive reviews over the years:

I'll search about the injectors you alluded to or you can advise me here. Better flow, more hp noted on the butt dyno / actual dyno before and afters?
Edit: I did find another thread where you mentioned upgrading from a one hole to four hole design. I also saw that you like RC injectors; me too, I run RC1000's in my Honda.
