noob questions/shifting trouble

I'm having a hard time down shifting, when I am slowing down at red lights, it seems like I have to come to a complete stop to go from 5th to 4th to 3rd and so on. I have adjusted the clutch cable to where there is just a little slack, maybe 3/16'' or 1/4'' of play. Oil change- So the engine case says 2200ml, so I fill it till it reads between the lines on the sight glass, and that was about 1800ml. So I warm it up for 3 min, then cool down for 3 min as suggested in the owners manual, was'nt really sure if that was enough, so I added a little bit more oil{just to be on the safe side},then I drove around for a bit and it seemed like it was'nt shifting right, so I got back home, let it cool down a few min, checked the sight glass and it was over full. I removed just enough oil so that it reads between the lines,{back to about 1800ml} then it ran/shifted smooth for about 2-3 months. It still has the same amount of oil in it, so I'm just not sure what the problem is. I don't ride it hard, I don't ride wheelies, I have put almost 20,000 miles on it since I got it new in July of 2008. 2008 GSXR 600

That's more freeplay than my bike can handle. I set my freeplay to barely perceptible and that's the only way I can hit neutral. Triumphs are special though. But it sounds like you are having a different kind of problem...

What kind of oil?

Any issues getting into neutral or anything like that, or just trouble downshifting when coming to a stop? And then it shifts fine when at a stop? that's backasswards.

I gotta admit, I got nothing on this one. Curious about the answer.

^^^as above.

Checking oil w the bike upright? Is it DUE for an oil change? Using motorcycle oil?


Check the shift linkage rod, make sure its not bent and at rest there is freeplay back/forth no binding.


First thing I would do is adjust that clutch lever w the cable so it only has about 4mm of freeplay.


When downshifting you are increasing the torque, so it will be harder to do so when the clutches arent fully disengaging.

When I down shift when I first got my bike I could down shift all the way down,click,click,click,click now its click, let the clutch out a lil then click repeat then click,click.

I'm using suzuki oil 10w40, just like the manual says, yes I check it with the bike upright. as for the freeplay, I'll try and adjust so that there is less play than there is now..but isn't 4mm and 3/16'' pretty much the same? I just changed the oil about 3 months ago, but I would like to take it to Sunny's and let someone who knows what they're doing do it, I know what it costs for a basic oil change + filter, but I'm broke at the moment and when it's simple things like brakes, plugs, oil, I would rather do it myself. Now that I live here,(apts.-H-town) I don't have a place to do the work or the tools to do it with. ^^^(yeah I already know)

Don't know - Not familar with the bike'

Cali has a good point on possible bent shift linkage rod.
Broke mine on a bandit (Bandit is Hydralic so may not be same) when it lost a chain - maybe something hit it.

When you start from a dead stop how far out does the lever go before the clutch starts to grab. Yes Iread you adjusted it. Not sure what the spec is for engagement, but if it is grabbing early it may not be fully disengaging when pulling the lever to shift.

Is all the shift linkage tight, and any bushings in the foot shifter worn, just trying to think of anything that could be adding some free play to the shift linkage system

If it all checks external - then I guess it maybe bike shop time for internal check $$

3/16" is almost a quarter inch.

i'd recommend you have just a little play, enough that you can wiggle the handle. If you have a caster adjustment on the lever, adjust it as far forward as possible.

clutch lever goes a lil more than half way out before it grabs, nothing is bent, I have had the linkage apart trying to change the front sprocket, I used a marker to draw a line so as to line it back up exactly the way it came off.. could it be clutch springs or friction plates weak or worn out??? I'm just thinking it's improper oil level, 'cause it shifts fine before it gets to normal temp (180ish)...anybody S.E. wanna look at it tomorrow???

the springs engage the clutch, not disengage.

If it happened after the sprocket work relook at the work performed.

Thanks Cali... I checked the free play and it was way less than that, maybe it was closer to 1/8''.. not sure what you mean ''caster'' is that the adjustment on the lever? It is adjusted almost all the way out.
