Last night I replaced the valve stem seals in my RS head because of excessive oil usage(~1qt/500miles).

Two of the seals on exhaust valves had come off of the guides and were just laying there loose after I removed the springs.  Do ya think that may have contributed to a lot of oil burning?

You were burning oil like a two-stroke Bultaco. This might be a good time to do a Seafoam (or other brand) treatment - the kind where you draw the Seafoam directly into the throttle body balance ports - so it can clean out some of that burned oil in the combustion chambers.

Yeah, Scud, my old Ossa Pioneer ran a leaner oil mix.   As luck would have it, the bulk of the oil was going straight into the exhaust so the piston crown and the head were pretty clean considering how much oil I was burning.  Exhaust valve stems were nasty as well the inside of the exhaust ports. 

Everything is cleaned up and ready to go now pending removal of the broken head bolt.

Ha! Barely above the numb-fingers temp range for me.

I use my old film grip gear for supporting the bike: apple boxes, dolly cribbing and wedges and sand bags to keep the front tire from rolling.

Mlytle how come you guys have white grass, we only get green or brown. And where are the wheels on your bikes. Must be hard going round corners and noisy.

or just a design that did not need repeated greasing.   car clutches appear to have the same design, yet i don't have to pull the tranny's to grease them regularly.  grease at install, good until the clutch wears out.  what is different about the k clutches?

It ain't so bad. Six hours of work every 50k miles is a small price to pay.

Have you had luck with the splines holding up with 50k lube intervals? I'm worried with 25k on mine

It's been 40k miles since my last clutch spline lube. No shifting problems, but I figured it was time to grease.

I take it that clutch hub and input shaft splines had a level of wear that's acceptable...?

I haven't had any shifting issues either though

My guess is that the shaft has less mass and is probably subject to more lash and shock that acts on the lube. I think it's a miracle they run as well as they do, or that I run as well as I do, come to think of it.

I've been kinda researching BMW dry clutches and one issue is that there's no pilot bearing for the driveshaft, which probably doesn't help

Replaced my aftermarket 7" headlight with the Truck-Lite 27270C LED H/L. Painless swap, even in the snow.

Previously I've used Hella 100/80W H4 bulbs and the better Sylvania 50/65W bulbs from the autoparts stores, and found they didn't last long, especially given that I take long tours. They're only rated for 150 to 300 hours depending on the bulb. That's like one summer month for me.

This light uses less than 1/3 the amperage of standard quartz bulbs which leaves more electricity for my heated gear.

road tested the valve adjustment and some beemer buddy overgrips.
amazing the difference from the valve adjust.  two of the exhaust valves were two sizes too tight, and the 3rd was three sizes too tight.  it started immediately at full choke and went to 2k rpm.  before it would start, but hover at 1500 until it warmed up for a few minutes.  seemed smoother accross the rev range.  yeah.

BB overgrips are great.  nice and FAT and very grippy.


ride took me into old town alexandia.  passed a K100rs heading the other way on the GW parkway.  anyone here?

stopped at fellow car guy's garage.  he had just picked up an old BSA bike to add to his vehicle collection.

If you fill your headlight full of water, they run cooler and you can put a higher wattage globe in them, and they last longer. :hehehe
