I'm on tank 4 of break-in and all I can say is WOW. I've never seen an engine that tight. I don't see how it's possible to bump this engine without preheating. It was giving my starter box a run for it's money

I will absolutely be changing the conrod (probably wristpin and clips too)at 1.5 gallons. I'll also go to ceramic bearings at 3 gallons. I'm gonna love this engine. I want it around for awhile. (Go Tech .25)

I'm following the MG66 as well. I'd like to use it in my 8T if the .25 turns out to be overkill. I'm more of a momentum driver so I'd prefer a .21 but our two local club tracks are loamy, old-school tracks. We'll see.
