I stand corrected. This one is even more! Both nice bikes. Wow.

The most expensive one I've seen yet. And hasn't met the reserve.

Just an idea. After you get it flushed out, is there a way to use a clear line and some kind of inline screen/filter temporarily? Just until you're comfortable the problem is gone.
Hey Stabler, sorry about your bad luck. That's like my worst frickin' nightmare come true. Loss of oil pressure. Sounds like you caught it before it did any damage. I'm sure you'll get it sorted out.

Nice, but he wants some serious cash.
The 450's gettin' closer. Need to finish the front brakes and do some painting. Too hot for that here today. 103.
I guess I'll move on to the XS650 next and then maybe a CB750. The wife and I want to take the 450 and the 650 for a ride on the Blue Ridge Pkwy. next summer. Gotta keep workin'.
It's just a slotted piece with a piece of some kind of plastic for wear. It moves straight up and down. I'll try and copy a picture for you out of my manual. It may not work because your chain tension changes with wheel movement. I think your idea of turning it on the tubing might be better.
Have you ever seen the tensioner on the primary in a Harley? It's a real simple arrangement and you could possibly do something similar. With your bike not having a swingarm, does the chain tension change as the wheel moves up and down?
As long as it's on the bottom, I would think it would work. Would you adjust tension with your normal tensioner, or make some provision for adjusting it (the tensioner wheel) and locking it down?
I guess the pros of the sprocket are a little more low end grunt and takeoff and solving your chain issue. The cons are the RPM and the gas mileage. I like the chain tensioner, but obviously the cost and time are definite cons. The pros would be a chain that is always at the right tension and...
