Quick question about the clutch basket...

Hi guys!!

Bike was in storage until last Saturday.

Took it for a spin, about 70 kms (or 44 miles) or so... Everything was fine.

Started it yesterday morning to go to work, at there's chatter coming from that side of the bike. Remembered a thread about that while I was at work, fixing helicopters...!! Read through that thread, and decided to open that side to check it out.

Got Home today, took the cover off and everything looked fine... I took all 6 bolts off, put some Lok-tite on them, put them back in and torqued them to spec...

Started it, the chatter was still there!! But after letting it warm up to temp, the chatter went away... Took it for a spin around the block, got snowed on but no chatter.

So I guess I shouldn't be too worried, right?? What's your take on that??

Mine is noisy on startup. Quiets right down though.

Right. I think these bikes have personalities, and most of them like to screw with us on occasion, just throw out some death rattle or random warning light, watch us fret, then smugly go on about their business of being awesome.

Thanks Qwik and Chuckracer!!

I was a little worried because she never quite sounded like that before.

And your right, they have a lot of personality!!

You might want to remove and check/clean the clutch oil jet.

Even if the oil covering the parts in there was looking good??

Mine always sounds like it's about to jump out the side of the engine.

16k miles later, it's still where it belongs.

No loctite needed on those bolts.

Manual:
"Mount the pressure springs with disks and bolts (M6x16). Tighten the
bolts crosswise to 10 Nm."

Well crap, I switched a couple plates in mine today and promptly used blue loctite when I replaced those 6 bolts. Guessing it will not be an issue?

Yes, and that's what the TB said as well. But it won't hurt, seeing what happened to fellow riders...!!

And as a precaution, the "Tighten the bolts crosswise to 10 Nm" should read "Tighten the bolts crosswise increasingly to 10 Nm".

Meaning 10 Nm equals about 88 in-lbs. So starting at 40 in-lbs, you tighten them, then go up to 60, then 88... Again, safety precaution.

Are you sure it is not cam chain noise?

No, I'm not sure. It comes from the right side of the engine, that I'm sure. And it really seemed to be coming from the clutch basket cover, at the bottom. And it was fading as the engine got warmer...

How could I be?

Check the clutch booster, if its gummed up and rusty your clutch jet is probably blocked. How many miles? They are noisy on the lc8....you could undo the clutch bolts and feel for side play....roller bearing could be warn if the jet has been blocked for a while.

The cam chain tensioners sometimes take a few seconds to pump up, but it shouldn't take as long as engine warming. You might want to search for info on the cam chain noise anyway, to compare symptoms.

The typical failure of the clutch system (from what I have seen and read about) is not the bolt that tensions the pressure plate springs, but the tower assembly that threads into the inner basket.... these become loose (back out). Personally, if there is any question, I would pull the outer cover, remove all of the tensioning bolts and springs, remove the outer pressure plate, remove all spring towers (the things that the tensioning bolts thread into) from the inner basket, clean all threads, apply RED loctite (or similar tech), install and torque to spec. Also remove inner basket nut and pressure ramp system, inspect and clean the ramp (the pressure ramp system is a WEAR ITEM... over time the ramps wear a fair amount...), clean the ramp bearing surfaces, lube and reinstall... then retaining nut with RED loctite, torque to spec. Now would be a good time to check all the clutch plates, its easy to get them out with a little piece of wire with a hook bent on the end.... keep them in order so they go back in with the same mating surfaces. If there are signs of over heating, check to ensure that the steel plates are still flat (they will warp and cause the clutch to drag when the lever is pulled making finding neutral at stop even more of a PITA). To breath life back into the clutch pack and/or eliminate that nasty howl/squeal that sometimes happens with these clutches I have used the following method with great success: Find a section of plate glass, tempered preferred (it tends to be more uniform/flat). If you have another true flat surface then used that... then glue down a sheet of 400 wet/dry sand paper to the surface. Wet the sandpaper with clean paint thinner/solvent and lightly sand the friction clutch plates, flush away debris with more solvent. Then do the same with the steel plates, but with more force, just enough to take the shine/burnished finish off the plate. Flush every part clean with solvent, blow dry and then flush with engine oil. A cleaning of and/or enlargement to .7mm of the oil jet will help keep things well lubed for a clutch that gets used/abused, however will make finding neutral at a stop a bit harder.

Reassemble parts into clutch. Personally, I used BLUE loctite on the tensioning bolts.
