2009 Street Triple Clutch Won’t Engage!

Has your drive chain broken?

 

Howdy Mohamed, and welcome in

 

Hi Mo,

That sounds as if you have a serious problem, it could involve a strip of the engine, as a first step try draining the oil and see whether there is any contamination, such as metallic bits which would confirm an internal problem, best of luck!

 

Stuck clutch plates?

 

Provided the clutch cable frees off at the end of its travel and allows the clutch springs to clamp the mechanism........

You have to suspect an internal breakage. The crankshaft drive is separated from the gearbox by the clutch. If the engine runs and you can change gear but no drive is transmitted then the clutch itself or the splines on the shaft have sheared.

I would go back to the downshift. Even a violent downshift would much more likely unstick the tyre than break anything but......

 

Mohamed.
Welcome to the family. Well check your cable is not screwed right out should have a couple of thou free play at the bars. Then get that cover of you may have striped you clutch plates especially if you have a slipper clutch on there it will have slipped out of the ball bearings. Do keep us all in the know. Also hit the upload a file button bottom right corner and show the inmates your steed.
Regards
Joe.

 

Sounds like the basket and plates need an overhaul but firstly check the clutch cable routing, especially that it’s not snagged at the ends

 

Yes. I would say having read that that the clutch needs attention and may have burned out. If your mechanical skills are up to it it’s not a difficult job.

 

Aaah! Now you think about it..........!!!

If you had clutch slip it won’t have gone away on its own. You have adjustment at both ends of the clutch cable. If it is too tight it prevents the clutch springs from clamping the plates in the basket. If it is too loose you cannot free off the clutch enough to change gear. The clunk you get engaging first gear is caused by the drag from the oil film between the plates - enough to cause drag but insufficient to transmit the drive.

It sounds like your cable is too tight. You should aim to have a tiny bit of slack at the lever - maybe 1/8” gap. Plenty of how to YouTube videos.

 

Good job on the bike there Mo. The clutch basket looks fine, those marks are to be expected on the inner and outer sections. As long as there are no deep grooves I’d leave it as it is. If you file anything down to remove any grooves you will end up with too much clearance when the plates are put back in and it will lead to premature wear of the new clutch.
The friction plates look worn out from your picture and need changing. It’s critical to put them back in the right order so I hope you took notice of how they were originally fitted, (assuming they were right in the first place) and you must soak them in oil overnight before fitting them. As long as the steel plates show no signs of overheating or warpage they should be fine.
Oh, and your bike needs a good clean and maybe a new rear tyre
Best of luck.
Ps. I wouldn’t go any further with the dismantling as there’s nothing behind the clutch basket that should need attention. Just spin the inner section to ensure it runs free with no nasty grating or grinding sounds and you should be good to go. The outer section is driven from the crank and the gear teeth look good in the picture.

 

You might have adjusted the problem out but I agree you now need new plates and springs as Yorkshireman advises. YouTube is your friend!
