Well i,m the proud new owner of a 01 400ex (Yellow)and when reading the book, it does not tell you how to to properly break it in.The only thing it says is when to change the oil and lube the chain and stuff like that.Can someone tell me the right way to do it. Thanks !!!!

 

Ride it like you normally would.
Just don't hold the throttle at one position for a long period of time.
Change your oil after the 3rd time out and get your vavles adjusted.
After that, ride it like you stole the *****!

I would recommend you keep the revs down for the first 5-8 hours to let everything seat properly. And I would change the oil every 5 hours
for the first 15. Then let her rip!

 

my uncel has a yellow 400ex and when he first got it we rode it hard and fast and when it was stock you could race another 4ooex and it would beet it he also has a 670 mxz ho and he rode it hard to and it will go 98 to 100 and the other peoples can only go about 92

 

i don't think it matters. just ride it and change the oil in the reccomended time intervals.

 

i dont know if its the same for the 400ex....but in my auzuki quadsport owners manual... it says to stay within the 1/3 throttle range and go throught all the gears. change the oil the first hour then every 5 hours after the first 20 hours. after that, keep it in the half throttle range and change the oil every 10 hours for the next 40 hours. after that...according to the clymer manual, the bike is good to go....i dont know though, sounds kinda rough being out on that new 400ex being teasted to open it up and not being able to if you want it to run right.

Thanks for the info guys. Keep it comeing if ya got something else i should know! Oh I changed my username to 400EXPILOT Thanks !!

 

don't go to full throttle, just hold it about as much as half throttle for at least the first 5-8hrs. to let all the rings and stuff set.

 

The people I bought my ex from told me to drive it like you normally would with no break-in procedure. they were so wrong. So, I got it off the truck, brand new, and took it easy for 2 minutes and drove it hard for the rest of the break-in. I regret it. Now after a year 1/2 it smokes blue puffs of smoke.(Mobil 1 synthetic 15-50 is suppost to fix that problem) Most likly because the rings are worn from a hard break-in. The honda owners manual says take it cool for the first 15 miles. I would go through 1 tank of gas with not much throttle, and then give it speed bursts, and change the oil after the initial 5-10 hours.
