Breaking in a bike

[gavjn]

i have a zx6r and am currently breaking it in, have done bout 150ks on it and missed second and hit neutral at 8k revs... is it bad that this has happend?

also, have heard many different things bout breaking them in, owners manual states that 1st 800ks go no higher than 4k revs and 2nd 800ks go no higher than 6k revs... i kno this is the bottom end mark so that they cant get bitten in the ass bout anythin, but 4k revs is NOTHING ><

wats acceptable?

You can do it however you want, most just follow the manufacturers specs and get it serviced when the warranty requires. You can search kb for threads on breaking in a new bike, there have been many!
An 8k burst wont kill it. But do warm the bike up properly before you ride it

Mate, this is yur new bike and you want it to last you a fair while before it starts using oil and gets clapped out.

If you run it in as per the book, you will be fine. You don't have to follow the words to the letter, just take it easy and don't over rev or strain the engine at too low revs.

It won't take long to build up enough Ks to start going faster.

The odd blip in neutral won't hurt.

Good luck.

Spinning up to 8k without any load on the motor won't hurt it. What really kills motors is heat, caused by (among other things) lugging the engine in too high a gear at too low revs.

so you still having to ride the gsx 250? that is really tragic.. they have ways of keeping the engine running for tests and what not at the factory, youd think they could break em in themselves, just keep the engine running at the revs desired, for the time desired, then sell the bikes as broken in from the factory..

lol yea the 250's shit, havnt riden it for a while, once i startd using the ninja i jst looked at the 250 with disgust and took the other 1 out.

at 4k revs the bike only goes 70kmh >< damn break in period!!!

No higher than 4000RPM for the first 800km? WTF?! That'd probably damage the engine due to bogging unless you only rode in 1st gear. Given you'll idle about 1400RPM it's pretty weird.

Fark you'd barely make 60km/h in 6th and the poor bike would be groaning

The important things when breaking in an engine is to not labour the engine at low RPM or rev it high while under load (like wide open throttle trying to wheelie etc). You want to gradually build up to to redline over the first 1000km but don't do it under load. If you're riding on the motorway change gears a lot so you don't get stuck on one RPM.

well only the first 800 km sound difficult, with the second 800 you will probably be capable of motorway speeds and will make it much easier to cover those 800 k.. just out of curiosity what does it red line at?

I am too tired to answer this one, pm Gordie on this site he will give you a concise answer on your predicament

[zzzbang]

call your dealer, they should have an answer more reliable than random opinions on the forum.

redlines at 16k

Judging by some of the stuff I've heard at dealers I think you'll find they just read KB to answer questions their customers ask

well i dont know about kawasakis.. but my suzuki dealer had a good break in method for me. start at 4000 rpm max for first 100km, then go up 1000rpm for every 100km you travel (until 1000km). worked well for me, got no issues. and.. since they sell the bikes everyday they are obviously going to have some kind of standard run in method to explain to their customers. Oh.. and important point... dont stay on constant revs, always keep increasing/decreasing it. (constant revs is supposed to make a mark in the cylinder which would cause the piston not to seal as well as it should later on)

Yeah it looks like this 4000RPM stuff is legit. I'm shocked.

My 600rr manual basically said "go for it but don't use full throttle or labour the engine for the first 1000km". The dealer said "nah nothing special... Just don't try wheelie it till after the first service" and laughed.

I'm inclined to believe nana-ing an engine is bad for it but it really depends on the engine and how much run-in it has had at the factory. Bogging and constant RPM is the real killer. Or lots of throttle on a cold engine.

Not sure I'd go this far on my own bike but this guy always stirs up a hornets nest.. http://www.mototuneusa.com/break_in_secrets.htm

Well, honestly i dont think its a bad idea. Been doing that on all our dirtbikes basically. Keep it calm for an hour or so to let it settle then ride/race like you want. Dont see why road bikes would be any different.
