98 KX 125...Help!
crazyolbastard:
I might not know much but that clutch basket looks thrashed.
Is there a max. on how deep those grooves can be before it should be replaced?
Friar-Tuck:
Hmm..
Well the outer basket can be filed down to get the notches out of the basket, you have to try to keep the surface flat so all the plates touch at the same time. Crazy Old was asking about how to measure the basket for a go/no go.
put a friction disk in the basket and take a feeler gauge and measure the distance between the tang and the basket.
New it's 0.15-0.45mm or(0.006"-0.018") the service limit is 0.8mm or (0.031")
That inner basket is not cheap...I had a friend who broke his and ran a bolt all the way through from the back and used a nut and washer on the front to hold the whole mess together. that was about five years ago and its still hanging in there... :-o I'm wondering if the kickstart is "Clocked" correctly, I have a copy of a kx250 pdf however I don't think it's the right year... :| Maybe it will give you an Idea on how everything lines up on the starter etc.
If the index marks on the kick gear and the ratchet are not lined up properly I don't think the kicker will work right...
I broke a bolt head on my XR600 basket I used a reverse drill bit and the bolt spun right out. I'll look up the spec for that bolt is 8.8 N.M or 78 INCH LBS. be careful ! :|
I don't quite get how that broke on the kid while riding... that part only holds the clutch springs in place.. :| any ways...
The impeller... If there are any bits left of the water pump impeller you should be able to find them in the head, cyl and rads.
Sorry to not to be able to give you a more definative answer...
I think that if it was my bike I would bite the bullet and take her down to nothing and start from scratch.
That's probably the only way to know for sure what you've got. Then she should be good for years of service!
Shoot me an e-mail and I'll send off what I have on a 125/250,

I'm wondering about that too long drain bolt...This may be a long shot... does that drain bolt have any marks on the end of it like it's hitting the bottom of clutch basket?

Tuck,
Ha ha, I don't know how the clutch broke like that while he was riding it. Yeah, I get what crazy old was saying about the basket looking rough. First thing I need to do is pick up a manual...That drain bolt I was talking about, you can see it in the picture of the "bowl" is where my impeller is supposed to be, you can see where it bored into that "bowl" part cause it was WAY too long. The drain bolt is shorter, it looks like someone used a bolt that was meant to be on the cover. Yeah, I won't be riding this bike anytime soon...besides this clutch issue it needs swingarm bearings, ( left side feels like theres nothing in there), needs rear master cylinder, rear fender, LOTS of cleaning...but, I only payed 400bucks for it. Fix what I need to, its ok with me if it takes a little time and a little money, at least when I'm done doing what I gotta do to this thing I'll have a pretty sweet bike...I just hope it looks as good as the rest of the KX's on here!
Friar-Tuck:
"Drain Bolt" I thought you were talking about the OIL drain...
Mystery solved on the impeller.... the bolt was driven right through it! Doh!
I have no doubt your bike will be great when she's finished. The last three bike I have gotten for myself have been in at least three boxes when I picked them up. :-o
You might do a quick search on swingarm bearings....they have a long history if they haven't been serviced...
But we'll keep that tidbit for later :-D
Take Care & best of Luck =)

That black plastic piece is your mechanical seal...keeps the trans oil and the coolant in their separate areas. Coop is right, pull the cover off and remove the broken water pump shaft from the back.
