Call all XR600R!!!

[Royal Club]

So,

I allmost don't want to ask this.. I know its been asked a zillion times, but all I read is people arguing on what is right...

I have a COURSE spline countershaft.


this model.

My sprocket has a flat side and a side with a lump..

which side goes outwards??

I have it set OUT-wards at the moment, the rear sprocket/chain/front sprocket/ seem to align pretty good..

I have always had the flat side to the outside.

this is my old sprocket, used with the flat side out. as you can see the sprocket has wear toward the engine.. dunno how to describe it correctly, the wear directs toward the engine.. the other side is pretty clean, no strange lumps and strange wear..

Then why does the sprocket have such strange wear on it?

How's the con rod and big-end bearing, and is it the factory rod or was it already replaced? I forget.
It might not be a good idea to run 11:1 compression on the factory rod...

IF you're going to swap out the rod, add two new crankshaft bearings to the list.

I would atleast change all the seals in the cases aswell as the gaskets, since you're splitting them anyway.
Gasket kits contain all kinds of o-rings, but not the seals.

Get a new camchain tensioner spring, just in case. They're like 3 bucks.


Oh, and add an oil filter and 3 liters of quality oil to your list

Slight misalignment between the front and rear sprockets. Could come from anything...rear wheel not set properly in swingarm..bent swingarm...twisted frame...etc.

Thanks deejay! The rod is Pro-X, no idea when it was replaced but looks good and no vertical play (though a little side to side but I gather this is normal).

What do you mean by the seal, sorry? I'll replace them if you reckon it's worth it, I just don't know what they are! Cam chain tensioner spring is a good one, I'll add it to the list.

I bought 8L of mineral oil today since the local auto shop was having a special on, saved about $35. Supercheap auto for those in Australia, $28 for 4L of Castrol Activ 4T!

And embarressingly I already have a spare oil filter...I bought it for the first oil change I was going to do at 500 km...but it never got there

But yeah I can get 4 of them for $13 from the site so I'll order a bulk amount while I'm there.

So: new seals (?), new tensioner spring and new filters...what else?

Thanks man,

John

is the wiseco true 11.1 or less? youre going all out man!

not a fan of the magnetic plugs, they are hollow and break using normal torque, you can make one yourself thats stouter.

good luck!

are you using the same numbers on the chain snail adjusters?

you must measure from axle to a fixed point on the frame or swingarm to see if your rear wheel is straight...a lot of times the adjusters are the cause of problems with bad wear at the front sprocket...

one assumes that equal numbers equals a perpendicular axle but no, you must measure

or you have a tweaked frame

I think the Bikemaster drain plugs are steel.

Yeah I am, and as said, from the looks of it the chain and sprockets are aligning..
