gregrob Posted May 7, 2008 Report Share Posted May 7, 2008 First of all, please check out this article so you know where I'm coming from: http://www.mototuneusa.com/break_in_secrets.htm Ok, how do you guys do it in the real world, and what have you found to work the best? My buddy (bigred) says to heat cycle it 2-3 times, then start riding it easy with 20:1 gas. Then after you run that tank out, mix @ your normal ratio, and ride it... He also said that one of his best running, longest lasting top ends came from warming it up, not even waiting for it to cool down, ripping up the street a few times then going straight to sand and laying into it. I'm kind of a fan of the latter method, not to abuse a brand new engine but because I have seen first hand that the rings need a load on them to seat properly. If they glaze over sitting there idling, you will never get the seal you could have once had... tell me what you think. Thanks, Greg Quote Link to comment Share on other sites More sharing options...
trex banshee Posted May 7, 2008 Report Share Posted May 7, 2008 honestly i can't tell ya one way or the other, ive done both....sadly all my stuff is drag raced once its warmed up, but all my customers and anything that i don't personally own are ran through somewhat of heat cylces..ive had great luck going both ways, my blue bike on alcohol is still running the same pistons for 3 years now, never done any break in on it but then agian everything was right from the get go. Look at it this way, if its not going to handle it now its never going to handle it....but then again there is always that "but what if i had taken it easy for a while" :biggrin: Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted May 7, 2008 Report Share Posted May 7, 2008 I do the sam,e thing only I do not change my ratio. I run 3 heat cycles of 20 mins each letting it cool 100% before the next cycle. then first ride run about 1 tank running up and down thorugh the gears but not pegging it out. then the next tank ride it like I stole it. The whole time running the same ratio that I always do Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 7, 2008 Report Share Posted May 7, 2008 I've read that article and I've always been a believer in that. I've said time and time again don't put anything in the gas tank that you don't plan on running on any given day....no special "break in" oil. I've got a buddy that swears on breaking in pistons on gas then putting a bike on methanol... The key is let the bike warm up then go for a ride. Period...especially with nikasil cylinders. Get it up to or damn close to operating temps...then rip. My 4 mil cub on gas went right from a few heat cycles to the dyno. It ripped ass...

monster_energy06 Posted May 7, 2008 Report Share Posted May 7, 2008 (edited) i break it in like i ride it. mix it slightly richer first tank so im my case i goo 32:1 first tank then 50:1 after that i just start it warm it up and ride it like i always do, it always worked out awsome. all my sleds and all my bikes have been brokin in like that. never one problem ....ohh yeah all my machines are pretty all run to the bar most the time haha Edited May 7, 2008 by monster_energy06 Quote Link to comment Share on other sites More sharing options...
shee rips Posted May 8, 2008 Report Share Posted May 8, 2008 i broke in this top end with the heat cycle method. since then i have read most of that guys stuff, and next time i think ill be doing it like that. now that i think about it, the last top end i did in my dirtbike, before i blew the bottom end, fixed and sold, i rode it pretty hard. the break in was a fast long logging road ride, and that thing ripped after...

sheerider1026 Posted May 8, 2008 Report Share Posted May 8, 2008 i heat cylce them about 4 times.. run about 1/2 tank. then ride it like i stole it.. always have great results.. theres a lot of friction when the rings are seating, and running the engine at high rpm's does not help matters..

dirtydownunder Posted May 8, 2008 Report Share Posted May 8, 2008 (edited) i dont get the whole heat cycle thing if some one can tell me what it actully does that would be great, piston ring to bore wear-in is simply to wear both surfaces together and this can only be done by running the two surface's together. if you heat things up and down enuff times the metal becomes fragile. i run my cars in hard and i did the same to the banshee, im always WOT but i dont let the revs climb to much, WOT change gear WOT next gear i just load it up without letting it rev out, and go thru the gears alot if its a new transmission. to be honest i dont think i could "correctly" run in a two stoke i meen B-O-R-I-N-G. who knows what the correct method is as everyone is differant. and im not too shaw about the running a oily mix becuase you can glaze up the bores and it will never run-in correctly or take even longer.

IrideA250R Posted May 8, 2008 Report Share Posted May 8, 2008 you guys that are running more oil for break in..do you realize that leans out the fuel to air mixture due to their being less gas in the mixture? Lean is typically not what you want during a break in procedure. I also let the bike warm up, and then let it rip through the gears. I don't hold it wide open though, just load the motor well in all gears. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 8, 2008 Report Share Posted May 8, 2008 you guys that are running more oil for break in..do you realize that leans out the fuel to air mixture due to their being less gas in the mixture? Thank you, thank you, thank you. I love it when guys say I just put a little more oil in the gas for winter riding (you know what I'm talking about) I'm like let me explain to you how cold air leans out the jetting. Then let me explain to you that more oil in the gas leans it out more... Here's your engine, here's your engine leaned out.... Any questions??? :thumbsup: Quote Link to comment Share on other sites More sharing options...

I just laugh and roll my eyes when people change the oil mixture to solve jetting issues as well... Quote Link to comment Share on other sites More sharing options...

My only question would be; my motor is a '96, is this considered newer or older? http://www.myspace.com/xxxbansheexxx Quote Link to comment Share on other sites More sharing options...
