Onto the cases.

After reading all the trouble that some guys go through to split
them, I was kind of bummed that it would be a pain to do like some
that I already had the pleasure to do.

Not even close. 3 small taps on the crank, 3 on the shaft and 3 more
on one of the cases "ears" and it was splited.

Easiest case ever.

Still on the fence about the gears. A couple of gears have some chips and the rest
are just scored.







Not sure if you can see it, but the chips are there.
What say you? Replace now or just wait until they start to jump?
They didnt jumped when I picked her up but I wasnt hard on it. I already have sourced a complete gearbox
from a NX650 for about 60$. Its complete and the guy also includes the shift shaft which I have to
buy anyway. Just waiting for some pictures to check the gears but he said theyre brand new looking.

I think Ill just change it and enjoy the wider ratio.

Does the shiftshaft and a countershaft from NX fit the XR? I don't see why not, but you're already there before me . I plan on spliting it when the season ends!

Hey nikolic, the shift shaft is the exact same part but not the countershaft. The NX650 one
is thicker where it fits the right case. Some guys that fit the complete gearbox just machine
it to fit the XR600 case.

I already have a new countershaft so Ill just sell the NX650 which is new by the way.

Dont forget to show us your rebuild

It's kind a hard to find XR parts around here, and as I know it, NX didn't have a countershaft problems! So if it
gets bad till the winter, I'll probably machine it! Thank's for the info ;)

The pitted gears won't JUMP as much as throw off little bits of really hard ass steel that love to score the piston/cylinder which leads to oil control problems. They will also start howling when the pitting gets worse. Your best bet is to replace the parts now which will save you all of the labor and gaskets to do this at a later date. Ask me how I know...

The biggest problem with tiny parts of scrap metal is that they can get stuck to magnet! So you
can ruin your coils!

Hey Steve, hows the leg? Ready to rumble ?
I forgot to pm you regarding the countershaft...sorry bout that. I found a new one in a dealership
that went bust and was selling parts at factory cost. I lucked out and they had one. Thanks
again for the help though.

Ill just replace yes. Better to e safe, right? Already alked to the guy to send me some
good pictures of the NX650 gearbox.

By the way, Steve, which spring is recommended to replace on the kickstart assembly?
The big one that locks it to the case?

If someone has that little plastic thingy that fits inside the kicksarter spring laying around
and wants to throw it my way, Itd be great.

Deejay your bike turned really good, I followed your posts it the supermoto forum too.
I was thinking of pmng you regarding your wheel setup.

I want to have a spare of street tires on it too.

By the way, since your from my side of the pond, do you have any good, relatively
cheap site for parts? Ive been using ebay with luck, but its always good to have
a direct source...

The leg is OK, the knees are shot. Perhaps this is why my XR is spotless after the restoration from a couple of years ago...

The big spring on the kickstarter shaft has never given me any trouble but here is the # 28261-MK2-000

Plastic collar # 28255-MG3-010

I know the feeling man, I had my knee cap, femur and right foot busted in a million pieces
from a car crash a few years ago and the knee is by far the most problematic. Im young
and fit and recovered pretty well but it still gives me grief when physically pushed.
Get well man.

Regarding the spring, I thought Ive read somewhere that they tend to break?
Maybe it was from the shift shaft. I have to go through my rebuild files to check it.

Hey thanks man !

My current wheel set-up is just 17" Excel rims laced onto stock (powdercoated) hubs.

I can't really help you with any good sources.
I buy a lot of things off Ebay as well, for used engine and electrical parts there is this local breaker in Holland that can usually help me out. New engine parts I order from The States. Last time I ordered from www.speedsupplies.com, because they were one of the few that ship outside the US & Canada.

What source for engine parts do you use?

Years ago when I first started hanging out around Thumper land on ADV I helped a fella whose XR600 transmission locked up and wouldn't shift. It turned out to be the real fine spring on the shift shaft.

Gearshaft Return Spring # 24624-MT3-000
