ADRIAN,
I understand this can be a "heated" discussion!
When you are breaking in your engine, you want to keep the "heat" down, The piston to liner clearance needs to "seat". And in the case of a ringed engine the ring to liner must "seat", "seating" means for the metalurgy to "match up" it is actually a wearing in process.
If you drill a hloe in a piece of metal with a metal bit, you put oil on the piece you are drilling to help keep the metal cool so as not to cause excessive wear on your drill bit. the same works for other metals, if you get them hot they loose their hardness, heat causes metal to "anneal" or soften. I do this PROCESS almost everyday working with gold in my shop. You DON'T want to make the metal soft or harder you want it to maintain the same
"MOES"hardness that the factory put into it.
Try it yourself with a DRILL AND DRILLBIT! Drill into a piece of 1/2 inch steel with oil and without oil, notice that without oil you "BURN" a bit up! Then use that same heat process and thought to break in your next engine!
lOTS OF OIL "very rich"LOW R.P.M. = LOW HEAT!
I use a "break in" oil, 10% nitro, 80% oil,20%castor for a total of 20% oil mixture. , "PERFORMANCE PLUS" is still made to this mixture. you used to be able to get it at "hobby people".
Break the engine in as the MANUFACTURER TELLS YOU TO!
There is more than one way to do it, but they give you a guideline to help with any questions you may have. (AND AS ALSO STATED ABOVE, TO HONOR THEIR WARRANTY)
As far as the "tuned pipe" goes, It won't hurt to break it in on the pipe as long as you keep it "OFF THE PIPE" "ON THE PIPE" is a terminology used to describe when the engine and PIPE is "MATCHED" JUST REMEMBER the PIPE is designed to give you added R.P.M. and as stated above the added R.P.M. is going to produce added heat. IF YOU DON'T UNDERSTAND THIS, BREAK THE ENGINE IN WITH THE FACTORY EXHAUST.
Any questions, please feel free to E-MAIL me or send me a P.M.
I MEAN NO DISRESPECT TOWARDS ED SMITH! Just don't agree!
Friends I fly with ran new engines on the ground in the airplane/helicopter at the time they are going to fly it, then they put it "IN THE AIR" I can show you an ENYA 35 HELI engine that was done this way, It needs a new piston and sleeve! also a T.T. PRO 46 That was done this very way, The guy "gave" it to me because it was a "BUM" engine, I sent to THUNDER TIGER for a PISTON,LINER AND BEARINGS. I've been running this engune for three seasons now, ON A MAC's PIPE, it's a power house! The guy keeps saying that "his never ran that good!" I WONDER WHY?
