When we (Mostly Ed) constructed the bike the accent was on strength, simplicity, and git-er-done. Now that I have time to revisit I am trying to shave a few pounds off it. The rear fender was a large piece of steel that served as fender, tank support and chain guard. Very effective but weighty. I replaced it with a small steel tank brace, a minimum plastic fender and an aluminum chain guard. (All that is enclosed in a rear streamline fairing.)

The enclosed chain guard-tensioner was sandwiched in steel so I cut some panels out of it and used some balistic tough polycarbinate for an adjustment monitor window on the inner-back side. (The front, leg side, has a steel screen.)

I pulled the head off Tucker's LSR, a '70 Triumph 250. It actually looked pretty good. I did my first valve lap job with a spring compressor I made from an old C-clamp and a 1" socket. Not fancy or fine but it worked. There was a learning curve, keeping the collar halves in place during installation with a little grease as glue helped. Anyway her engine is buttoned up now and I can get back to the 500 thumper, the Big Red One.

I boxed and weighed everything I trimmed off my 500 APS .  The bike is now 22 lbs lighter.
I built a new chest bolster for it, compared to the nard busting, sternum cracking 1/4" padded original, 3 inches of foam is like laying on a cloud.
My wife struggles mightly to kickstart her 250 MPG with its 12:1 compression so Ed found her a through the spark plug compression release gadget.

My XR 500 suffered a catastrophic seizure last year due to an engine cowling/fairing that was just a bit too efficient. I cannibalized the cowling to let air get to the air cooled engine and thought I might go one better. I made some air scoops that I just might attach if the ambient temperature starts getting too deserty.

Salt clogging the fins can be an issue, too.

Indeed, I have seen the salt clog fins and turn into concrete. I will be running the same front fender as you see in my ID picture, worked pretty good last year.

When the big stuff is done you turn to the little things to kill time untill race day.
I hung a small leather tool bag on the lower part of rear fender to carry kickstand zip ties, snips and goggle wipes.
Rigged an easy on/off spring to insure the kickstart arm stays folded in.
Zipped the wire harness and applied a hose clamp so that the weight of the throat and filter doesn't hang on the spigot stlye carburator manifold.
Made an alternate front fender. The original steel one is more aerodynamic with ears that shield the fork tubes but the fiberglass alternate saves 8 lbs according to the bathroom scale. (That seems a heavy read.) I plan to run both and compare times.
Race day better get here soon before I do something really foolish. See ya at BUBs Bonneville play day!
