kevincurtis Posted March 20, 2012 Report Share Posted March 20, 2012 Was just wondering if i could get some info on Properly Breaking In a new Top-End / Crank, Lots of opinions out there. Would like to know the proper and right way to get the most life / performance. Thanks Quote Link to comment Share on other sites More sharing options...
Phelps Posted March 20, 2012 Report Share Posted March 20, 2012 mix it 20:1 and ride it like you stole it for the first tank. swap the plugs and mix normal and ride it like you stole it again..... seriously though as long as you run the proper oil ratio it should be ready to go as soon as it hits operating temps. if it fails it was due to not being built right or a bad part.

ticktock Posted March 20, 2012 Report Share Posted March 20, 2012 There are quite a few posts here on this. Look up heat cycles. I personally don't ride it like I stole until I have done proper heat cycles. Adam Quote Link to comment Share on other sites More sharing options...
special06shee Posted March 20, 2012 Report Share Posted March 20, 2012 (edited) there are many theories out there.. i personally like to bring the motor up to temp and do a light mx style ride for 15mins or so then let it cool down completly before doing it all over again. i do this for about 1/2 tank. I personaly believe that this is the best technique because you are putting positive and negitive charges on the rings to ensure they seat right. Is this the absoulute best way?? who knows. It works for me!! i know that starting it up and letting it idle in the drive way for 1/2 hour is not a good idea!!

Look at the 3000 hp funny cars the run fresh rebuilds in between runs. They don't do get cycles or any thing. Kevin at HJR said if it breaks you did something wrong. So start it up see if you hear anything then ride it. I don't go blasting out the garage, I'll just run through the gears and then it's game on from there Quote Link to comment Share on other sites More sharing options...

EvilBanshee Posted March 20, 2012 Report Share Posted March 20, 2012 Im gunna be the one who disagree's, The rings will seat better after a few hours of running. Like i just said on another post, My 421 gained compression after 3 hours of hard run time. I agreee, Dont baby it, Let it get warm, and run it hard. The rings will seat better under high load.

ticktock Posted March 20, 2012 Report Share Posted March 20, 2012 I was never worried about the rings. I was worried more about the piston skirts. The let it warm up at idle ride varying throttle to 1/4 for 15 minutes. Let the bike cool. Then ride again varying throttle allowing the power band to about 3/4 of throttle then start getting into it. Add more oil will cause a lean mixture which can be as bad as lean jets. I have alway run a 2 stroke this way and never had problems. You mentioned top fuel drag racers. They don't get many passes on those motors before they are rebuilt.
