Lighting circuit is separate from what I understand as well. No, nothing at all was done to the bike. Old headlight off, new headlight on. Plug and play. If it ain't right, you'd never know it by the light it outs out.


A proper "holy shit' moment from today.

Have a look at these pics and tell me if you see anything wrong.


Cylinder looks great:



Compression ring looks good:



Oil ring looks good:



Do these valve stem seals look properly seated? Not sure about this one?
Intake side valves:



Exhaust side valves:



It's definitely burning oil, lots of buildup on the piston and the face of the valves.





The back side of the intake valves looks pretty gunked up leading me to thing the intake side valve stem seals are leaking?

Well, I finally got all the parts in and got it all buttoned up yesterday and did a quick 10 mile Motoman break-in and then an oil change.

Ended up going w/ a new Wossner Piston (94.97mm since my XC-W had a Type II piston) and rings. I put all new valve shaft oil seals in, cleaned up the head and the valves and did a valve adjustment.

I gave the cylinder a quick hone w/ a flex hone and for the first time used Total Seal Quickseat Dry Film Powder for the cylinder/rings installation. We'll see if it helps.

I used a Flex-Hone in 240 grit Aluminum Oxide, not a silicone carbide hone and did a lite pass to deglaze the cylinder.

Bike seems to pull really strong.



Today I did a 70 mile trail loop today and the bike is running strong w/ no oil consuption. I'll have to put on a few more miles before I can be realy certain everything is OK

Interested to hear how this works for you, Dan. My 530 has been strange... one ride it may go through an alarming amount of oil; like half the site glass in 40 miles. Then I can ride it 4 or 5 other days, hundreds of miles, and it uses nothing. Totally random; can't figure it out. I carry a little oil with me, just in case.

Any tip overs when you use oil?

Could be pouring oil down the crank case breather tube and burning it when dropped.

Other wise it might be the valve stem seals that are not seated properly.

No tip overs. Well, not every time. I haven't taken the time to check the seals; been riding too much. I will, though. They may be seating, and unseating randomly.

I you keep riding while burning oil you risk getting lots of buildup on the valves which could keep them from closing properly.

It needs to snow, then.

How about ice?? We went out yesterday for a few hours, and today, just the two of us rode in the freezing rain. The 350 EXC is very quick on ice, and is a little easier to ride, but the romp of a 530 can't be beat. The 530 with the BD headlight has a rather fecked rear tire, and is squirly, but is fun to hang out at 110 km/h. Good times, I'm whipped.

I've been riding a lot too.

That is awesome. I wish there was a lake around here to do that on. I wonder if Deep Creek in Maryland would be ok to do that on when it freezes.

If we get enough cold weather, sure. I've ridden sleds on Deep Creek years ago.

Nice shots,very scenic riding you've got out there.
I got in 80 miles of singletrack last weekend in nor cal,the snow has melted off and riding is great! We had 18 guys show up for sunday's ride,split up into 3 groups. One gentleman of a certain age (70) went for a swim in one of the deeper water crossings,only his helmet and handlebars were sticking out of the water for a moment.
Not the thing to do in November really.
I was on my 300 and had an absolute blast racing nose to tail through the woods sat and sunday with a friend on a 530. Got away with only one minor tip over.
