ok my friend said that the 250r should be ran at 10,000 rpm all the time if not it will start blow out black smoke alot. so does this mean i should run it at 10,000 rpm when im going like 35mph.or should i shift into sixth and cruise at like 4,000 rpm

 

Actually, you need to red line it all the time. 10k is definitely not enough.

 

Or a better option is to not listen to what the 'friend' says. I don't know where people get such stupid ideas. I'm not calling you stupid by any means because you just didn't know. But your friend sounds like an idiot.

 

ok were you kidding because you think my friend is stupid or should i really red line it everywhere

 

Don't redline it everywhere. And if it's shooting black smoke at lower RPM's you need your carb adjusted cause it's running to rich.

Mine doesn't shoot any color smoke at any rpm.

 

Sorry, I'm just being an ***.[&:]

If you are breaking in your new engine, just keep your rpms varied.

If it is already broken in, it makes no difference what rpms you run it at, but higher rpms will just put more wear and tear on your engine. I keep my bike around 5-7k rpms most of the time.

 

10k RPM all the time!? Yes, he is an idiot.

You run int he top half of your RPM range for performance (ie - carving up the twisties). You run in the bottom half for normal driving and better gas mileage.

Think of it this way; if you are doing something that would benefit from more torque, run higher RPM's. If not, then don't. And of course, don't run RPM so low that the engine bogs down (3k or less?).

 

hahaha, a good but funny question. I like the non-assed post by mark and also the one of fizzit's post.

 

mines not blowing black smoke now he was telling me to inform me but i thought he would be wrong about that, cause on the way home i ran it high and it sounded like i was killing my engine.

 

they rev to the moon they have used the same motor for 20 years change your oil do your maintence it will de fine
