KB mythbusters - wear-in period?

[Captian soup]

Iv been doing my research for my next bike.. and Iv come across somthing that makes me scratch my head..

Wear in periods.. Iv googled it and gotten mixed answers, on one had theres the "it's for the best", on the other its "give it shit"!! A guy I know that works with new cars is told by his boss to "thrash them"... I wore in my ninja but have nothing to compare it to.

I ask because Iv seen a few bikes with really low ks around that wouldn't have finished their wear in period and the sellers going on about how fast it is.. and I dont want to buy a dud.

[superman]

Oh no, BIG CAN to open. Make it a poll and see, spread usually seems 50-50 thrash it or be nice. Logic from both makes sense... so really what we need is someone to get two bikes the same, thrash one and baby the other. And then dyno them.

[Latte]

Who cares

There's always gonna be a faster bike than yours so don't worry there. And if you're prudent and get a decent mech to do a pre purchase, then keep up with the service schedule you would be ok imo.

I'd seriously doubt any issues that occur could be attributed to how the previous owner rode it (within reason of course, those f*tards on youtube bouncing their bike of the rev limiter etc don't count, and you'd probably pick that up from the trademe add wit da txt spk seyn bk is rly mnt duz menaz skidz au).

It's pretty simple. Has anyone had a problem by following the manufacturers run in procedure?
There's your answer.

can of worms buddy!
probably going to be 50/50.

one side will argue that you need to be nice, so that items can wear in or bed in properly, so that gaskets seal up properly etc etc etc.

The other side will say that you need to take the engine to all of its tolerances, and that not doing so means that it will never reach its maximum tolerances.

Id ride it like i normally would a new (to me) bike, sedately at first, and work my way up to its limits, see what it does and how it does it, find all the handling and engine anomolies and characteristics etc etc

They both make sense! With the awesome quality of manufacturing nowadays they probably design it so it beds in better for one way or the other, so just do whatever they reckon

That sounds like what I'd do if I ever get the chance of having a brand new bike

Along with lots of oil changes for the first few thousand kms

[Captian soup]

just one of those things then huh? crap... i see the logic on both sides hence my confusion.
im also paranoid and believe that if a big corporation has to pay up if something goes wrong while under warranty period they will do whatever it takes to protect themselves.

has anyone in the auckland region have a 09 ninja they have not worn in?

ok..thats nothing like what i done...wish i had though...

Ride it like you stole it. I take it easy when my bike is cold but I have revved it hard and fast since day 1 when it is warm. The manufacturer says this is ok in the manual, so why not. It runs very strong. It uses no oil and the oil stays clean.

Taking it too easy can glaze the pistons and pistons. Running it too hard when it is cold is also bad. Avoid those, and service the bike regularly and you will be fine.

[Woodman]

Don't lug it and don't over rev it, pretty much normal riding really.

The only thing that needs "bedding in" on a new engine is the rings, but with todays build quality they are pretty much good to go.

I agree with frequent oil and filter changes from new. Change oil and filter at 500 km. Then at 1000 km. Then change the oil every 3,500 km - i don't change the filter at the 3,500 and 7,00 km changes. I put my bike into the shop every 10,000 for a professional check, they change the oil (again) and filter at that time.

A motorbike engine oil is very highly stressed because:

• there's generally less of it
• a motorbike engine has a higher specific power output than a car engine
• it also revs higher
• the oil also lubricates the gearbox
• an air cooled motorcycle engine will place higher thermal loading on the oil
• motorcycle 4T oil has to have the right frictional characteristics for the clutch operation, these frictional characteristics wear out and you might find you have gear change glitches toewards the end of your oil drain period.
