i put my 02 bike in first gear and ride in circles. the speedometer says 5mph riding only on the clutch by letting go fully no throttle applied. however, when i ride around in circles (sidewalk to sidewalk in the middle of the street), it does not die but it starts to shake like its about to die.
so i am wondering if this is normal or the bike should be able to ride smoothly in circles with the clutch released.

is it also possible to know what rpm should i be at if going 25mph on first gear. for example say my bike goes 25mph at 5k rpm in first gear, but perhaps it should be doing 25mph at less rpm on first gear. i just do not know if my bike is lacking in power or not. any help would be appreciated, thank you.

 

Are you stunting? or practicing slow circles?

Bike motors, like most all engines, have almost NO power at idle. And if you apply load to an idling motor and it drops below its idle rpm range, it's going to shake rattle and pop.

Gearingcommander.com...... will help you figure out what speed you should be at depending on RPM. Which says at 5k rpm with stock gearing you should be going 24.9 mph. You're right on the money.

 

Is this your first bike? I don't mean that in any way except a question. Need to know what your experience level is with bikes

 

yes this is my first bike and i was just practicing slow circles

 

Any experience riding before this? Have you taken the MSF course or gotten your license yet?

 

on the f4i if you let the clutch out slow enough youll be able to ride at idle without even touching the throttle. But doing that while riding in circles could be too much load on the engine if youre going slow enough and drop the rpms enough to make the bike about to stall. So it could just be that and not a problem at all. Try doing it in a straight line down the street and see if the bike still shakes and rattles at idle.

 

You need a little maintenace throttle. Don't try to idle, without a little touch on
the gas. That's how you control the size of the circle after you lock the bars to the
tank. Sounds wierd, but look over your shoulder in the direction you're turning. Then
use the throttle to slow till you start to fall in/stall the motor. Then add a little, you'll
lean out into a bigger circle. All the while, the bars are tight to the tank. Then rev it
up a little, this will stand it up so you can bring the bars back up. Then follow it all of
the way over to circle the other direction.

It's a lot of fun and great at building co-ordination and fine throttle control. Not to
mention confidence.

Yes I have taken the msf course I just wanted to know if my bike is running like everyones' else and it seems to be that way. Thanks for the info
