Here's how mine was done.Huntray said:Having a 95" build & SERT completed on my '05 Deluxe w/ +4K currently on it. Is there a correct or quick way to break-in as my Wrench states that I should put approx. 500 miles on it prior to Dyno?

3-4 heat cycles, ridden for 500 miles max 3000 rpm, dyno, let her rip.
Lots of disagreement on this subject.
Do a search.
Hello Huntray...........definiteley a debatable subject on here if you go by past threads.......Huntray said:Having a 95" build & SERT completed on my '05 Deluxe w/ +4K currently on it.

This is exactly how I was told to break my build in. Now 7k later no problems, no oil usage, nothing. I think this is good advice. Mikenw_guy4_fun said:I do agree with the OZ method
I feel the rings with modern materials and machining methods are broken in after the first ride or sooner. That said piston fit with some of the hypers should be very tight and until the cyl walls get a little poilish to them I would want to avoid scuffing so I take it easy until after the first tank of gas at least. Load and unload the first ride but keep it below 3k.
For more information from experts consult the websites of Bishops Performance, Axtell (tech articles), S&S (install instructions), and Hastings ring co just to name a few.
Hi adlerx, did quite a bit of racing myself, used to put a fine taper on the undersides of the rings and change hatch angle to improve breakin time and reduce friction to gain a few so called free horses but rings would only last a few races.adlerx said:
He,he,he. Those instruction are for old russian boxers with SV engines. but basicaly it is Harley factory instruction of breakin in:SamC said:
Isn't that kind of a contradiction of statements? maybe not for built motors with a little bit down there, but for new stock? Anything below 2500 is lugging the engine on a new stock motor....Don Camillo said:1.during first 50 miles RPMS under 2500 in any gear but do not lug the engine.
Well, guess the speculation that Dan Aykroyd was importing czech bikes was not totally correct. They are Ukrainian.Before each departure it is desirable to warm up the engine. For the best work of the engine recommended gasoline octane level 66-76. If octane level is higher, the engine will overheat and the piston group may burn out.
