Here's something from Duncan racing about breaking in your new fourstroke. This is what I will do when I get mine!! Have fun breaking it in!!

Naaaaaaa.

Do it like I said. Break in those rings the right way in the 1st half hour. This is a crucial time. It's up to you. Break in in like you stole it and have a "faster" machine 9 times out of 10. Or you can do the "suggested" way. lol. You think Duncan's top riders break thiers in like that? lol. Hell no. They do it right...like they stole it.

Warm it up for one couple minutes. Then go ride it they way it's supposed to be ridden.

DITTO THAT!
New quad are pretty much broke in when you get them anyway, if your putting the HRC kit on I would consider it since it is a new cam in a cylinder head that has been ran some.

yea i broke my 400ex in that way....soon as i pulled it off the truck...i was ridding wheelies up the driveway and givin her hell...i knew she would hold up...come on now its a honda....altho.....i can say....id never break in a yamaha like that....too scared it would break down...i bet money if i pulled a yamaha off the truck (not saying that it would ever be a yamaha on my truck) but if i pulled a yamajunk fresh off the truck and reamed her arse and kept it pinned....i bet money it would break or not act right...so i agree...break it in like your going to ride it...its pretty much the same concept with buying a new car....you dont go to the dealer ship and buy a brand new vette and just poke arround...the 1st thing u want to do when they hand you the keys is pinn it and atleast lay a few burnouts to see what shes got........ride it hard....breaks it in better...

You honestly thing that Duncan would post the proper procedure for breaking in a new bike then go and do something different. You are nuts.

I'd run a tank or two through it before you run it hard. I know it is hard to do but it WILL make more power if you brake it in properly rather than just running the piss out of it.

I rest my case...

Like I said....that's how we do it.

Ya Ya I've seen his articles before. It is kinda funny though. EVERYONE besides him in the industry says to take it easy the first little while on an engine. I would be willing to put money on that the manufacturers have put LOTS LOTS more time and money into r&d as to what it the best way to brake in a bike. Not to mention all the r&d engine builders such as Duncan have put into it. I guess they are all just stupid? I don't think so. I have heard time and time again stories of two identical bikes that one got the crap ridden out of it from the get go and the other was broken in properly and the properly broken in engine ran better and had more power. I think a lot of people go along with what this guy says because they want to just go rip on their new bike and this gives them the excuse they need to not feel bad about it. You all feel free to brake them in any way you choose but I'll brake mine in properly thank you!
