Im just breaking in my new bike but someone told me that more revs is better. Suzuki manual states that I should keep it below 5k for the first 500 miles but a friend told me that higher revs all throughout the powerband help the valves seat better. So which is it? Low revs? Or high revs? Im hoping I can rev it throughout becuase the powerband is crap below 5k I have to shift into 3 or 4th to just keep up with traffic. So anyone with an opnion please chime in and show some proof if you can. Thanks.

This is a huge debate and no one will be able to give you a positive answer. Some sware by riding it hard from the beginning because it ends up with a couple more horsepower. Others think that's a crock of shit, and only follow the manufacturers reccomendations.

I think the only thing for sure is don't sit at one rpm's for a long time, you want to keep varying your rpms during break-in.

 

[BadNatured]

So should I worry about taking it above 5k? Does it mean anything? or is it just horse shit and its kind of one of those "rather be safe than sorry" ty pe things.

This comes up all the time. Why would the manufacturers tell you to do something that doesn't make sense? Their instructions work for most cases. You can go a little over 5K once in a while. That won't hurt. People who race their bikes may break them in harder to get a few more hp, BUT they rebuild their engines after every race weekend. Do you want to do that?

Why not take it out and put 500 miles on it in a weekend varying the speed but under 5K and be done with it?

Because my ass isn't that tough hahaha. Ive only ridden like 10 miles a day. That and its too hot here to ride alot. I have a riding time of approx 5-8ish at night or 7-10ish in the morning. The time between then is hell on earth.

 

[YetiMoto]

Ok I'm new and all but I'm now new to new engines.. yeah... I think that makes sense..

ok here goes... like the above posters... Variation and load, are really the key things you are looking for. You want to stress the new parts but not go all nuts on it.. I wouldn't think twice about honkin on it every once in a while, just don't hit the rev limiter..


After breaking in two-stroke snowmobile engines and being around snomobiling all my life, I can say that if you ride it moderately give it some gas when you feel like it, VARY your speeds and RPM's you should be fine, hell I've adjusted my chain twice already on my 2k4 gsxr, but thats me.

 

[MadChild]

Vary your RPM's for sure. Don't let it sit in one spot for to long. Bring it up to 10k once in a while to more load in the engine to let things set a little better. But this topic is up all in the air. Its all personal perference. I did mine hard and moderate, and there is no problems.

 

[Kawa-ZX9]

I say do the hard break in . I broke mine in like a grandma, now at 5500 the bike does not rock and roll.

yeah, rev it up if I could do it again.

 

[Tripped]

:lol I've done both ways... I broke in my last Gixsxer hard and had no problems, it was stolen at 35,000 miles. My current bike I bought at 20,000 and don't know how the hell it was broken in. If you rev it make sure you change the oil every 50-100 miles or so up to about 750 or so. You will be amazed how much crap will fall out. That is not crap you want suck in the bearings.

 

[Nostradumbass]

Why is it so important to vary the RPM's? I've hear plenty of explanations why you should break the bike in per manufacturer's recomendations, and plenty of explanations why you should ignore the manufacturer and beat the piss out of the bike. But I've still not heard any explanation why you should vary the rpm's.

OK, get some padded bicycle shorts to wear under your gear. You've got 6 hours per day. At 40 mph average, shouldn't take more than 2 days. :lol

I believe the goal is to not leave the pistons/rings at the same temperature for long periods. Varying the rpms and temps will help seat the rings better.

 

[DreddR6]

Broke my R6 in at the track. . . Rev'n like there was no tomorrow, red lining, keeping it in the power band, bleh bleh , blah, blah, halb, halb. . .

18k Miles later, good portion of which on a track and she has not missed a beat. I did change the oil 3 times before 1k miles, and change it after every track weekend or 3k miles...

Lucky? I doubt it, just about every racer I know has broken the bike in at the track.

As for rebuilding the engine every race weekend? MotoGP bikes, sure I buy it. Maybe some of the AMA Factory bikes, ya, ok.

As for everyone else, CCS, WERA, um all the European circuits, I serriously doubt it. I know when I'm out at the track for a fri/sat/sun and once in a while mon, I dont see everyone rebuilding there engines! Pfft.

 

[BadNatured]

See, ive red lined it once (didnt pay attention when shifting) but other than that I keep it between 4-5.5k. Even here people are disagreeing. I guess ill just drive around in a fashion that lets me move as I see fit. There doesn't really seem to be a right or a wrong way. I don't know how to change the oil on my bike, since someone said change it every 100 miles. Unless someone wants to help me out with a walk through, I know dick about motorcycle engines just how to do normal car oil changes. I think I am just going to ride it around town and just have fun. Its under warranty for 4 years anyway, screw it.

I have broken in all my bikes what some might call the hard way. Still 5 to 10 yrs down the road they sell well with no problems.

I broke in my new '03 Honda 954 like my '00 Honda 929 & the '97 Yamaha YZF600r in less then 5 days for the 600 miles & YES it was stinking hot. While I did not hit red line I was scooting well over 'on pipe' revs very early to even high revs in short bursts.

Main problem is trying to be clear of cops that want to nail me for speeding. Whatever you do DO NOT lug your ingine or put loads on the engine & keep the gal up in the range it likes being 5 thou & better along with lots of shifting as the cog box is asking for that.

Here I loose out for I do not know what you have & can only go on the 4-5 thou sounding like you have a 600.

DO not lug your engine? Pardon? Can you re-explain that second to last paragraph? Im lost. I have a SV650. So explain please.

wtf?

 

[TTsixxer]

More important than break in is oil change. On a new motor, (at least on car engines I used to overhaul) you should change the oil and filter after the first ride home. Those first few miles is were the motor breaks in the most. There will be more metal shavings inside your crankcase on those first 10 miles than at 3000. After you change the oil ride it normal and redline it every now and then and change the oil AND filter again at 100 miles, do this again at 250 then at 500 and then at 1000, after the first 1000 miles you can start the usual 3000 mile oil change intervals. Changing the oil and filter is the key for a good break in.

 

[Zyankaly]

ok here it is, a 50cc to 74cc 2-stroke is far more sencible then those big 4-strokes u got and i know that ppl that ref it high at the beginning, did not have that cilinder for very long....

also my old cilinder had a slow time at the beginning and it was the cilinder that didn't brake for the longest time in my area

all i can say to this.

 

[Adempha]

Just for the record, my 636 break in (according to the manual) was supposed to be under 4k for 500 miles, under 6k for 1000 miles. I obeyed this very strictly. However, at 1001 miles I was going deep into redline in all gears at all times, etc.
I'm at 8500 miles as of today, one year later and she "The Blue Sex Ninja" is a beast. I'm scared to open her throttle up all the way. I would do it the same way again.
