If all this is true, then he needs to call Yamaha and see if they want to buy it back and use it for marketing or something like that. :thumbsup:

Is that good hours?..... what do you mean? Seems like that bike is clapped out or some info is missing.

i have a lawn care business and i have owned zero turn mowers with kohler and kawasaki engines on them and have seen like 3300 hours on 1 machine before i sold it and it ran fine. it did burn some oil but not to bad.. why wouldnt one of these bikes last 3000+ hours??? if taken care of and never ran hard?
another note, i have a r1 sport bike with 19000 miles and runs as good as new no work. and a guy i ride with has like 38000 miles on a honda and runs great.

just like my first bike 86 kx80. i was 12 years old and me and my brother rode that everyday hard and 4 years and never rebuilt top end. when we bought it they told me dad every 20 hours replace rings. well that never happened and thing ran fine and never a problem.

I have a problem with comparing a high performance motor with a lawnmower. But, I do beleive that if maintained on a regular basis and ridden to church and back on a sunday, these hours are acheivable. I'm sure greyracer will weigh in on this....

Wow! That is a testament to the Yamaha 4 stroke. 1200 hours on a high performance MX bike without work is incredible. You can't compare these to a lawn mower engine. You probably should install a new piston rings and timing chain to ensure you get even more hours out of it.

Does your lawn mower turn 12K RPM's and hold 1.4 quarts of oil?

see, thats the thing. the guy is like 50 years old and i never see him rev it out. he uses it as a back and forth trail bike and is putted everywhere. i dont know if it was ever ran past like 7000 rpm's
but i guess the hours are good then

1.5 quarts and turns like 3750 rpm's but then again thats what those engines are built for.. just like these 400f is built to turn 10,000 plus rpm's

Not any lawn mower I ever saw.

But the R1 turns that fast quite easily, and faster. 19000 miles at 60 mph is 316 hours. The mileage isn't that hard to believe. My '03 left home with about 400 hours and had never needed a valve adjustment. There was another guy here a while ago on one of these threads who ran an hour meter to 700 on a YZ426.

1200 would be the most I've ever heard of, and of course, I'm skeptical, but I'm not prepared to say it's impossible under the right circumstances.

the hours you quote with the miles isnot near true in normal driving. a guy that does landscaping by me too has a gmc truck with a hour meter built in with the miles came like that stock, anyway he has 30,000 some thousand miles onit and 1500 hours. he told me he estamates about 40 hours per 1 thousand miles. your hours would maybe be right if there was no traffic and no lights.

In a truck you would have a slow average speed, but the typical crotch rocket rider will easily average 60 MPH.

and a note lol.... the hours i said were wrong. the guy did not know there was a little dot so the hours on his 400f are 124.7 hours not 1247. like i said hes a older guy and just putts it around his land. i stopped over to have a beer and looked at the hour meter and then showed him the dot.

How would he get that confused? You think he would wonder when he rode the other 1000 hours lol.

124.7 hours isn't unreasonable at all. A lot of people get more than that.

No kidding. There is a big difference in 100 and 1000 hours. :thumbsup:
