Break in Procedure?

[motorida26]

Hey guys, I know I've seen a Thread about this SOMEWHERE, but after looking and the Search function not working, I decided to post a this.

Whats the proper way to break in a new piston?

More specifically, how did you guys do it and how did it work?

Thanks.

well i usually just start the motor.. wait till it gets warm... thut it down and let it cool... do that about 3 times.... then go ride for 10 minutes not very hard... not over half throttle.... (but dont ride it for more than 15 minutes at a time) for like 1 day (or longer if your prefer).... then 3/4 throttle for 2, 15 minute intervales... lettting it cool off inbetween... then calmly and maturly LET THAT BAD BITCH RIP!!!

i run about 3 or 4 heat cycles, then a little trip around the yard and then let her rip. not saying thats the proper way, but ive never had any problems.

i had to take my 250r apart after like 3 hour of riding and it still had the cross hatch and the groovs on the piston.. so i am very careful about that shit

I've never heard of doing it like that, start it and let it run while just tapping the throtal for about 10-15 minutes till it completely warms up, do this about 3 or 4 times letting it cool COMPLETELY between each time, i mean stick your fingers inbetween the cooling fins and feel for any heat, should take 30 min to an hour to cool off depending on ambient temp and if there's a breeze or not. After that ride it around real easy for about 10-15 min but dont get up in the power band, but dont keep it at the same revs for very long. Let it cool again then next time you can rip it up but i still take it kinda easy on it for the first ride or two. During all of this run your oil at 32:1

this is how i do it


start it up let it idle for about 10 mins then shut off let it cool check plug

start up again and blimp the the throttle soft then matrulley to top rev then shut off


then start up and run it threw all the gears to make sure the fucker pulls all gears thats were all people mess up U HAVE TO MAKE SURE THE JETTING WILL PULL ALL THE GEARS. BUT USE THE CLUTCH NO POWER SHIFTING AT THIS POINT

THEN LET IT RIP AND LET THE 2-STOKE SCREAM
