How does the cam look?
Do all the top end bearings while you are in there.........you should be able to find most of them at a bearing house.

Hopefully the great LC4 hivemind can help me, i`m looking at a 2007 450 SX-f muffler to replace the boat anchor hanging off my tail end right now. Anyone know about if the header sizes are similar to stock?

boon boon, measure the bushing od, and if it is 26 mm, then our hunch is right.

if that's the case, you need the bearing and seals for the 525 exc, i have a 2003 (first year model) 525 exc and has 26mm axle.

Big thanks for all this info. I've been shopping for a second front wheel on my 03 (to run street tires) for a couple of months. I knew I had the smaller axle but wasn't sure exactly how the setup changed with the wheel replacement.my assumption was that they used the 03 OEM hub with just a different rim, so my assumption was that the spacers I had were for a 20mm hub. Thus, I was shopping for a wheel with the old style hub. But seeing these pics make me realize i need to take it back apart to check the OD of the spacer because the top portion of the pic looks like what i remember seeing on mine. the bigger hub used on the newer bikes is good news for buying a new wheel. it opens up better options for buying much newer used.

Anyone ever have an adjuster screw (for chain tension) freeze up? It is basically just a screw going into threads. How can it be froze up? No outter signs of rust? I tried heating it up. Am I missing something simple here? Any help would be much appreciated?

enduro0125 · 12-23-2012, 04:16 PM

Steel and aluminum don't play nice together.
The bolt should always be slathered with never-seize.
As a long time KTM rider this has been a known issue since the late 80's,I do this to all my bikes.
Unfortunately its Too late for you now.

I think someone posted on this(maybe early in this thread?)

nfranco · 12-23-2012, 04:58 PM

Try some PB blaster on the screws overnight and tap on the head of with a hammer in the morning.
