really Ive run several tko's no problem, and Boca's are supposedly better, quick q, and i know u have plenty more know how than me ralph, but with the ceramics, tko's especially, i was told u have to let them warm up real slow before blippin engine, as it cause "flatspots" knowing that i purchased a competition heater for the head, running tko's in a particular off-road motor for 6 gallons NOT a HICCUP bro...but i was told about the ceramic bearings skidding when engine is not heated up to running temp and was told early on, when engines hot, THAN you can blip, just a precautionary with ceramic bearings that i dont think everyone knows about...lmk if that could be the case if so, tell them you preheated etc etc ...lol...

The main problems with RC bearings is that no one knows what the real specs are. If you go to the better bearing manufacturers like INA and SKF you can get a complete book with the specs of a cetain line of bearings. If my engines would adapt their bearings I would not go for RC bearing companies who are getting customers with nice ladies in bathing suites, I would choose the real quality.
I am also running an engine with a 12x24 main bearing, it is a standard size so it is SKF, these bearings last for ever, even after several blowned up engines.

Use muratic acid and a qtip if the aluminum is on the chrome. It will bubble some at first and when it's done just wash it off with wd40 sand sleeve lightly with 1500grut paper and it's ready. Don't get the acid on brass or aluminum parts , it will eat them up.

? there r 3 options aviailable for the rubber o ring on the back cover for the nova motors, .15 .20.25 does anyone know what the different thickness does to the motor. also when raising the timing does it give more top end and less bottom, or more bottom or just more all around power...

I guess you meant to say increase timing that's what confussed me
I will keep my thought's to myself on that 1 & let the engine Guru's chime in
