Hi Duke,

Same problem, same fix, just different side of the seal failing.

Easy :-)

There are two seals in the carrier, one for oil, the other for coolant. Assuming the seal for oil is compromised, it could explain the leak.

That's what I thought. I replaced it once before when coolant was leaking. About 60 hrs. ago. Luckily it only took me about 20 minutes to replace it.

It only leaks a little when the bike gets really hot, so not urgent.

Be careful not to damage it on the shaft when you put it on. I think the kit you have on order from Travis will have a protector for it. If not just use a bit of electrical tape on the shaft to cover the end.

Yep, it has a little protector on it.

Check the cam too. The seals have a habit of grooving the camshaft and even new seals have a hard time sealing. If yours is looking iffy you can try to smooth it out with some emery cloth to see if that helps. If not then it's time for a new cam.

Other than a few updates, the 520 is the same exact motor as the 525. The biggest reliability update to do on the 02 is to swap the cam gear out for the later style. The old one has a bolt with a nylock nut that acts as the auto decomp stop. In some rare instances, it has been known to come apart and then you have a couple steel parts floating around that can get into the crank. Also there is a lower cam chain guide upgraded with a screen to prevent anything but oil from going into the crankcase from the stator side.

How many hours does this bike have. Anything more than 300-400 I would pull the head and have the valves inspected/replaced. The stock KTM ones are soft and wear pretty fast.(300 hours for me, ridden hard with some MX in there) Kibblewhite stainless steel valves (oversize if you have a shop that can cut the seats is a bonus) is the ticket. Those valves will go beyond 1000 hours easily.

I'm at 147 hours on my '05 525, and I just adjusted the valves. This was the first valve adjustment that I've had to make a significant adjustment- the intake valves were tight! I figure I'll be doing the Kibblewhite valves eventually.

BTW- have I mentioned how much I love this bike lately?

Seat

Anyone do the Guts comfort seat? soft/med/hard? it is supposed to be wider and flatter than the stock seat for about $120.
I have a Ranazco on my DR and it is a great seat but cost much more.
Wonder if the Guts would be similar?
any other options worthy of investigating?
I do not want something taller.
thanks,

Yes!

I highly recommend the Guts lower/wider. I bought it for a long-distance seat, but have since ditched my tall seat- it's that much more comfortable.

Go for it!

I was looking on the Guts site. So...you have to buy a kit and staple it together? The EE seat I bought was all together in one piece. I do like the idea of a soft WIDE seat.

Question:

I've got 13-52 gearing. I like the tractor feel offroad but could compromise a little.

1.What would be a good middle of the road gearing? I think stock is 15-45.

2.Or should I do separate gearing for each set up and what for sreet?
Stock is 14/48. I use this gearing for Dual Sport riding and its great as it can lope along the pavement at 65 MPH with the throttle just cracked, however my bike is a 570. For stictly off road I switch to a 14/50.

For my Sumo set-up for the street I use a 14/42. Great for the 2nd - 4th gear corners and still tops out over 100MPH. I've used 14/48 and 14/50 at the kart tracks.

Enjoy your motard set-up!!
