07 600rr jumps foward during 1st gear..

Hey guys im playing on my new cbr and i notice my bike jumps forward when i first put it in first gear. Do i need to adjust something or is somethign wrong =(? I remember in msf course whe putting the 250s in first gear it was very smooth so i dont think this is normal.

1)ignition
2)kickstand up
3)engine start
4) clutch and put in first gear,
5) bike jumps just a bit.

make sure your clutch is properly adjusted.
i prefer about 1/8"-1/4" or so of freeplay in the lever, it shouldnt be tight as in 0 play, but it shouldnt have excessive play either.

this reminds me of a question that i wanted to ask about clutch play. I removed all of it because i was hearing an odd noise in the engine case during low speeds... after removing the play, it went away. Could this be an oil issue?

thanks for the quick reply. I just read the manual about adjusting the clutch free play.

The measurement of freeplay is the amount of wire in that area correct?

Forgot to state that im a noob.:icon_lol:

^^ the amount of freeplay is how far the lever moves before it actually gives a bit of resistance (begins to disengage the clutch). as stated 1/8-1/4 of an inch is generally a good level of freeplay. you can go up to half an inch if you want. from your symptoms, it sounds like you have TOO MUCH freeplay, or you're not pulling the clutch all the way to the bar.

Every tranny will kick into 1st gear hard. If you have it in gear and it's trying to roll, that's another thing. But the hard putting into gear clunk is just how it is.

I know this sounds funny but the rattle is normal too. There is the clutch pressure plate, a bearing and a pin. The pin attaches to the clutch with the bearing, and (that arm that moves on top of the clutch cover) inside pulls the pin releasing the clutch. When the clutch lever is fully released, that pin starts to spin and the end rattles around in the arm piece that pulls it. That why it takes just a little pull on the clutch lever to get that to stop making noise. Just let it be a Honda and don't try to stop it from making that rattle.

also keep in mind that the 07 has a higher idle than the older ones so that will cause a little more jump as well as the fact that if the oil has not came up to operating temp even with the clutch pulled in there will be some parasitic drag on the clutch plates causing them to spin slightly when put into gear.

its the same thing that causes your rear tire to spin on a rear stand even if the clutch is pulled in when you are in gear
