Grabby clutch on 06 450F

9 posts in this topic

Has anyone else had this problem with their 06? I don't notice it at speed, but when trying to take off the clutch is very grabby and lets out a groan, very similar to my old 426 before I did the 01 clutch mod. I plan on talking with my dealer about it tomorrow (they're closed today) but was wondering if any of you had any ideas.

Looking at the parts book, I don't see the boss spring in there, but it isn't shown on any other 450 either. That one part might fix it, but wait to see what other '06 owners say.

Try a different oils - I notice it when the bike is cold....I may drill out some more holes in the hub or basket like I did in my 03.... :crazy:

Nope, I didn't notice it. I did notice that it is a long clutch pull though (not sure what you call it). When you first take off you got to be a lot more gas and not let go of that clutch till its almost out there. Im unsure how to adjust it, so I keep it how it is.

When Im riding it seems fine though, normal. What I was reading in the General forum is people not using there clutch when upshifting, or sometimes downshifting, just easing off the gas, now I always used my clutch because the last thing I want to do is go rebuild my transmission, what are your thoughts on that?

Clutch use is clutch abuse! That is my thought. I rarely use the clutch at all. For starts and some cornering and whoops that is all mainly. Been doing this for years and no tranny problems yet....upshift downshift, on the ground in air....no issues. But I do it carefully and methodically :crazy:

It did it on whatever Yamaha puts in there, and it's doing it with my current Mobil1 gold cap... I tried adjusting the freeplay and that didn't help, I'm nervous to ride it much more before doing something major for fear of smoking the clutch. My first oil change came out cleaner than expected, so I was shocked when the dragginess persisted. I'll keep you all updated if my dealer has any news for me.

My dealer was no help, the mechanic basically told me that all 450's do this and I'll just have to live with it :crazy: I may try an 02 426 inner plate/flat plate/boss spring and see if that clears it up. I may even try a different oil... I have no idea where to go from here other than open it up to see if anything is amok in there.... any suggestions?

My 450 is smooth, no sounds or grabiness.

My 05 RM250 however did have the same issue you've got with your 450, but then the RM250 was known for not having a strong clutch.
