Duke Posted August 2, 2006 Report Share Posted August 2, 2006 I was wundering what u should when breakin in a new shee. I was thinkin of goin through a tank of gas while takin it easy but im not sure? :shrug: Straight out of the owners manual: 1. 0-10 hours- Avoid continuous opertation above half throttle. Allow a cooling off period of five to ten minutes after every hour of operation. Vary speed of the machine from time to time. Do not operate it at one set throttle position. 2. 10-20 hours- Avoid prolonged operation above 3/4 throttle. Rev machine freely through the gears but do not use full throttle at any time.

watkins Posted August 2, 2006 Report Share Posted August 2, 2006 (edited) you are going to get different opinions on here, but here is my method: 1. Warm it up to operating temperature then shut it off, wait for it to cool down completley and re-torque all the head bolts. 2. Repeat step 1 4-5 times. 3. Ride it like you stole it. Never had a single issue doing this. I've never "babied" a top end... seems like a complete waste of time.

FasterThanU90 Posted August 3, 2006 Report Share Posted August 3, 2006 do a search to get better info but mostly just accelerate and fully decelarate dont go above 4th for a little while its better to breakin a bike in a small hilly area works really good in the woops or on a track just let it warm up to the touch and kick it into gear and go the first couple hours are the most important to seat the rings just keep snapping the throttle at diff rpm get it up to about 3rd then kick down the gears let the motor decelerat not the brakes and it will blow out all the crap the wears off the rings keep acc. dec. stay at diff RPMs and after the day drain ur oil do this about after 3 times of taking it out and ur good to go get a comp. gauge too take a measurment when u first start it when the gauge starts goin down and it stays at a consistent pressure ur break in is over Quote Link to comment Share on other sites More sharing options...

bodge Posted August 6, 2006 Report Share Posted August 6, 2006 I second that method. Except I'll heat cycle it three times, recheck torque, then RILISI. is it same if you have had the bottom end re built? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted August 6, 2006 Report Share Posted August 6, 2006 Yep...nothing really to break in on the bottom, just bearings. The top end needs for the rings to seat.... Quote Link to comment Share on other sites More sharing options...
sredish Posted August 7, 2006 Report Share Posted August 7, 2006 (edited) they key is not to cruise the quad at a given rpms or ride it at a consistent throttle position. the rings need pressure to seat, the acceleration and heavy deceleration give them the pressure needed to seat. 1. Fire it up, get it to operating temps for maybe 8 or 10 minutes and kill it. Let it cool completely. 2. Repeat step 1 and retorque. 3. Ride for 10 or 12 minutes 0 to 1/2 throttle once it warms, not moving the throttle slowly, you want to give it 1/2 throttle and let off varying it A LOT. After times up, let it cool completely. 4. Ride for 10 to 12 minutes from 0 to 3/4 throttle just like you did previously and then let it cool completely. 5. Let her friggin have it. By now you have 20 or 30 minutes on it and she's ready, just continue to try and vary the throttle quite a bit and not cruise for the first hour or so. The first hour is the most important on setting the rings and ensuring long life with no blowby. Only way to break in a motor... http://www.mototuneusa.com/break_in_secrets.htm Edited August 7, 2006 by sredish Quote Link to comment Share on other sites More sharing options...

yfz450killer Posted December 5, 2006 Report Share Posted December 5, 2006 I have seen and heard that warming up and cooling down and not staying constant in speed makes a difference. I have built 100's of 2 strokes and the one thing I have to come to realize is this. If it is going to break it will usually within the first 30-an hour. Fire it up, running it a little rich is best for breaking in a top end, rev it up a few times, get on it and beat this piss out of it. If it is wrong or defective you will know, but if it is right then it will last for as long as you take care of it. Quote Link to comment Share on other sites More sharing options...
kb7kuh Posted December 5, 2006 Report Share Posted December 5, 2006 (edited) When I had mine bored, I did 3 heat cycles took it easy for as long as I could stand it (about 1/2 hour) and then rode it hard. Never have had any problems. Edited December 5, 2006 by kb7kuh Quote Link to comment Share on other sites More sharing options...
Animalman294 Posted December 6, 2006 Report Share Posted December 6, 2006 Yeah, I'm going to talk to Jeff first, but I think I'm going to run a few heat cycles, then ride it at different throttle positions, then go like hell............... :beer: Quote Link to comment Share on other sites More sharing options...
