I was wondering that too,I remember the clutch pack in my cb650 was metal facing aspestos cork stuff covered metal. Maybe it acted like a seal going between steel and a porous surface. It is a shame you can't get better aftermarket clutches for these things.

Hey water warrior did you ever resurface a flywheel?

Nope, never had the pleasure or need to do the deed.

But I did have a little trouble with the coatings on clutch plates you mentioned. Some of the materials can be a little porous. Once I did a no no and put in the wrong oil for the bike and the oil was absorbed by the plate coating. And then the coating proceeded to swell up and reduce the plate clearances. The clearances came back as the plates wore a bit.
Not one of my finer moments but nothing was damaged. I have to admit to somehow using Dextron instead of moto specific oil. I did switch to Motul 2 stroke specific oil and the KDX was very happy after that.

At least nothing was damaged. I found out a few days ago that I need to replace the clutch pressure plate and flywheel in my nissan hb.

That's going to cost a bunch.

I do all the work,clutch is under warranty so just out 100-120 for flywheel and trans oil. Just super pissed. Owned this truck for six months and have burned three clutches,new transmission two fuel pumps one fuel tank...so sick of working on this pos.

Well what's causing the burn out? There has to be another remedy other than resurfacing every couple months

Get it running and sell it. Take the financial loss now rather than further down the road after more repairs. Get a cheap little pick up with rear wheel drive.

I think the clutch plates are crushing because the flywheel is shot out,I have replaced everything between the flywheel and rear tires at least once so my only guess is it needs resurfaced. There is no reason I should be burning a clutch plate every 3 months.

the aliment pins between the engine and the transmission may be musing
