Improperly disengage clutch ~ revs high, lower speed.

[Ntotot]

I kept wondering why I rev high and yet the speed doesn't justify with it. 100km/h for 8.5k on 6th. 140km/h for 13.5 on 6th.

So I ask my buddy on his green ninja what's his rev on 100km/h? he told that its around 7-7.5k. Then i checked with 250r maintenance book (courtesy from kkim ) ... i found that my clutch lever isn't properly fixed. the clutch did not disengage properly, leading to higher revs but didn't deliver the speed. I fix as per instructed and now the bike cruising 7.5k on 100km/h..... after 14 months had her!.

so you guys better check what ever mentioned in the Ninja book.

i just got back from a 30~40 Km ride and noted that i have the same issue (problem?) when im in 6th gear and going 100 Kmh, the rpm reads between 8500 to 9000. i thought this was normal? im not a heavy guy, about 62 Kg, which is around 130 pounds i think.

it was a little windy, but it wasn't like a 100mph head wind or anything, lol

any tips as to what page in the service manual i need to look into, or if there is a simple way to see if the clutch is fully engaged when i release it?

i do have this feeling that the RPM doesn't rise very linearly to the speed.

huh, i have the manual, but on page 2-23 there is this:



different manuals?

[andrewexd]

umm im not sure, i dont have the book itself, just look in the link.

[adouglas]

The manual at that link is for the FI bike, not the carbureted one.

Here's the one for the US bikes:

lever not adjusted properly? you mean the lever should have about 2-5mm of free play?

you'd better check them up.

too little the clutch won't engage, too much the clutch will not disengage properly. meaning to say that the clutch plates and the flywheel will not gripping each other properly thus giving stress to the engine resulting in higher revs but lower travel speed.

i did mine and it runs smoothly for 5 days now.

anybody done this yet.?

i want to do mine, how did you do yours? lol

did you only have to adjust the cables like this:


or did you ended up going into the engine?

just twist the screw towards the lever not the other way. make sure the locking screw and the cable screw meet close together.

So you didn't have to remove the fairing ?

i played around with the clutch cable on the steering wheel end, and there has not been any change. there is about 3~5 mm of free play, which should be right.

im wondering if my Speedo is calibrated differently...? i checked it out again yesterday, cruising at 100 Km/h in 6th gear, with no strong wind, the bike is doing 8500 Rpm...

im still 1000 Rpm over the norm it seems. i haven't done any mods. all stock, almost 2000 Km done with lots of oil + filter changes during the break in.

any way to know if the clutch is engaging properly when fully released besided the speed/rpm thing? taking off the engine/clutch plate cover is also a little out of the question, since it might be nothing.

uh..that's odd
i way to know is 1) the shift from 1 to 2 is smooth and not as loud as before 2) you can feel that the momentum when the clutch is released. 3) you could also see the speed - rev is relative.

btw, it is also possible that the speedo - tachometer need to be calibrated or replaced. there's a case here and it's the instrument defect.

generally, you don't have to rev or stress the engine just to cruise 100km/h. right?

this time try to use human intuition
