So it's been a good season. Put 2400 miles on since the middle of July on this tired old engine. Had a lot of fun, burnt a lot of oil.
After Maxpete and DanielBlack recently did their starter gear fixes I figured I couldn't let them have all the fun so thought I'd join the club before pulling the engine while it's still above freezing here. Wasn't having any issues with my clutch but was interested to see what I might find there as well
Tipped her over, crash bars are handy for this too, also placed a padded jack stand at the rear of the frame.
Couple of buggered clutch spring screws so someone had been in there before.
#3 JIS Impacta screwdriver made short work of removing them. They will be replaced with XS Performance Socket head bolts and sleeves.
Kickstart washer stuck to the sidecover.
In our inimitable Maxpete's words:
I reached around and popped the bike into first gear, re-mounted the rear brake pedal, pulled down on the pedal to lock the rear wheel and hit that 29mm nut with my electric buzz-gun.
That puppy had that 29mm nut off faster than a bride's nighty.
29mm nut here too but this bride didn't give in that easy. Took a little extra love with an air impact.
Now here's where it get's interesting and where I need some advice from you guys.
Once I got to the clutch pack and removed it I found metal filings in the bottom of the basket. In my excitement at this discovery I didn't get a picture, but here is where they were.
It appeared to be a small sheared off pin and some assorted filings, so I carefully cleaned them out. But once I pulled the needle bearing out I could see that one of the pressed in roller bearings had grenaded.
Here is the clutch pack.
Fibres are within spes - 2.96 - 2.99mm
Steels are within specs - 1.36mm
Also springs are within specs - 34.6mm
They are very hard. I cannot dent them with a fingernail. Looking at the bottom fibre plate you can see a groove worn in I expect from the pieces of that roller bearing that I found.
So questions:
1) Because of their hardness, should I replace these fibre plates? Not a big deal, they're still available OEM.
2) One of my clutch cush springs will rotate and a second will move slightly. I have read a comment by 5twins that this is a pretty involved and expensive job. I can see that as I guess you'd have to drill out the factory rivets and then replace with the special bolts and springs that come in the Mikes kit. First of all I don't relish the idea of this job and also don't like the idea of having nuts and bolts parts that could potentially come apart in place of rivets.
Will these 2 loose cush springs cause me a big problem, or will it be ok to reuse this?
3) I see the OEM needle bearing
93341-23504-00 is unavailable. Mikes/XSDirect sell a needle bearing with thrust washer kit.
Any recommendations or opinions on this kit?
Thank guys, I appreciate your opinions and advice.
I reached in the rag bag for an old T-shirt to cover her up and pulled out this old shirt of one of my kids. LOL.
Lets hope this will be true for her again someday!
