brake-in a new bike on the track? Obviously i've been thinking about getting a new moto and was just wondering if i took something off the showroom floor and went to the track with it, it wouldn't have the proper brake-in according to the manual I know it's a mixxed bag type of question and everyone feels different about it but i kinda feel i'd have to do some easy dirt riding on the thing before i just opened the thing up
Any thoughts?
Thanks

Here is a good read for ya.
Motor break in

Great, so if i get this thing over the winter, i won't even be able to start it
That's a good read and "sounds" reasonable

It's odd but every bike I've seen that's had the S$#T kicked out of it from day 1 runs great and usually makes more power that the same bike that was broken in properly!! Ride it like you stole it I guess. BTW I broke mine in the way Kawasaki said too!! Of course I thought I was gonna kill myself for the 1ST 500 miles, It has a hell of alot more power than my old ZX-10!

Let me see if I understand the question....

You want to know how you should "Brake-in" a "Race Bike"????

Ummmmm...How bout , you break it in during saturday morning practices.....There's a couple heat cycles for you right there.

Then....You race the fucking thing.

Oh....Don't forget to change the oil after 15 races.

Don't worry about longevity........When it blows up...you can buy a new motor and post pics......and shit.

You should pick up an older model for operational spares, just in case

My bike is broken in on the track every year. Plus top ends 4 times a year. It's ideal to break in a bike at loudon. Lots of variation in rpm and load in a lap.

I know where there's one, but it has dirt on it as I type this, you wouldn't like it

[Idiotboy]

How can there be dirt on it when you don't ride it ?

[legalspeed]

No it wouldn't. Follow your manuf. specs.

Then wring it out.

Still hasn't fallen off from the last time I did, thats some quality dirt I tell ya! over 2 months

Direct from the manual...

1. Fill the fuel tank...
2. Perform pre-operation checks..
3. start and warm up engine, check idle, check operation of controls and the "engine stop"button. Restart the engine and check it's operation within no more than 5 minutes.
4. Operate the machine in lower gears at moderate throttle openings for 5-8 minutes.
5. Check how the engine runs when the motorcycle is ridden with the throttle 1/4 to 1/2 open for about an hour.
6. Restart the machine and operate it for 10-15 more minutes. The machine will now be ready to race.

CAUTION:
Piston, rings, valves, camshafts, and gears require about 30 minutes of break-in operation at half-throttle or less.

Seems kinda simple by Yamaha specs

Then why not do it?

What you are doing in break-in is shearing the peaks off from the rings-to-cylinder-wall contact area.

If you don't break it in easy, you will tear those peaks off (instead of shearing them cleanly) and leave deeper valleys than the material can seal.

Hey Tully, don't you love it when Danny Boy gets all technical on us? OH DANNY BOY!!! Engineers these days huh DANNY!!!

Seriously though Mark, he's right. Do what the manual says, then ring the ever living shite outta it!

[R7]

I'll do what the manual says, i've always gone that route in the past and never had any troubles, why change now
See ya at the track

[Paul_E_D]

Sheesh, How many of those things do you need??? I wouldn't mind turning one into a street machine

[R7]

One of them is a street machine, registered, insured AND titled
The YZ426 and WR street moto are both up for sale

[LM954RR]

I think this thread needs some more close up pics....Just for good measure.

Ever wonder if the above mentioned break-in proceedure is the cause of your 4 top ends a year?

[gixxer6]
