I run a fiberglass tank on my "race bike" and it's best to drain the fuel from fiberglass after each use. I don't use clamps for a quick-disconnect. I see they're gettin' cracked, I'd better replace them. I do use hose clamps at an event with tech inspection. Dellorto PHM 38 is my carb of choice for this engine.
These Harley tappet blocks like to crack right on the slot's sharp corner. Doesn't really matter if they're aluminum or cast iron - they both crack. Sometimes there's a little casting mark(like this one) and that's where they crack. You can weld 'em or braze 'em . . . however, it may be best to find a different block. Maybe relieve that edge just a bit with a tiny Dremel? If that piece breaks off, it's not gonna be good.
I have possession of the "original Noot's" bead hone for tappet blocks. Works for many brake master cylinders too. It appears about worn out, but still works great. I run it in reverse and it works the opposite side of the honing beads, then back clockwise to smooth up the bore. The wire ends leave micro scratches to help hold oil in the bores. I slow the rpm way down and use long strokes to get the crosshatch running with the bore. Michael gave me 2 pairs of blocks, so I checked fitment with a lifter . . I'll use the best for a set.
This diagram is for oval track stock cars, but you can implement this method into motorcycle oval track racing (especially short tracks) where you don't have much of a straight. Slightly offset wheels, slight camber of wheels. Old school racers say it works - for faster corner speeds, . . . different methods for cushion tracks or hard pack surfaces. You probably can't get too crazy, 'since I assume your chain is running a bit off? I see the European racers shaved their tires at angles to get more surface area(contact patch) on the ground for different tracks. Anything to gain an edge.
Iowa boys to Phoenix. I stopped to see Jeremiah on Saturday (but shop was closed) so I walked next door to The Haifley Bros. to see what was new . . . and as always - busy as hell. The Arizona weather permits sanding and body work outside on most days. Someday I'm just gonna walk in and point, and say, "I'll take that one." They told me I can do that anytime now Noot . . .
I took a weekend off and went to Phoenix for a visit . . . The Arizona Antique & Classic Enthusiasts Club and has nice show and swap.
I wanna buy a bike and head for the desert !
They had a sweet turn-out of vintage (non-Harley) . . . but I bought a set of K Model pistons at the swap meet . . . and should've bought more stuff (decent prices).
Jeremiah was a bit "under-the-weather" all weekend with strep and fever, so that kinda sucked, since usually I get to hang around and hone some cylinders, or grind some valves? He did muster up enough strength to meet me Monday (on my way to the airport) and fire up his TROG knuckle racer for me. Lots of projects at Love Cycles as always. He's always been the best host, and we always have a fun time talkin' shop and catchin' up on all things vintage H-D. See ya'll soon and good luck at TROG in June. -Noot
Ironic photo, since it appears he's riding a Triumph ! ?
Scott was an AMA Grand National Champion in 1974. He raced Triumphs, raced for the Harley-Davidson factory team, then as a privateer. Gary Scott was an excellent professional motorcycle racer, but sometimes he could be a real asshole. I guess he slugged Bill Werner in the mouth once over something? Maybe he deserved it? Scott claimed a few motors, said a lot of words . . . but hey, gotta like the dude 'cause he goes like hell !
Anyone want to buy some old stroker pistons? I cleaned 'em all up, and they aren't scored or anything. Nice condition. They are just cool - Buy and Collect ! Trade with your friends ! Just neat to have on the shelf.
(PS. I can measure them and get you an exact size if you're interested)
Build a Stroker - Rebel against society ! Buck the system ! Disobey the Speed Limit !
Live a little !
I'm turning into a "side valve" guy, since they just run so good, never need much maintenance, always start . . and always get me to where I wanna go. If you can ever get a Harley 45 you'll really like it. (rode to coffee, then to work today - cold as heck out, that wet kind of cold) I found myself laying my (gloved) hand on the heads to warm up my fingers.
I save all these FM magneto parts, then I build my own. I've never bought one all complete (kinda expensive). The original Fairbanks-Morse parts are good - and I like anything NOS (still-in-the-box). I have a great source for charging magnets, checking coils, checking condensers, etc. and troubleshooting. I have a magneto firing the plugs in about everything I run. Most times on a "magneto fired" engine when it won't start, the first thing that gets blamed is the magneto . . . since it's the most misunderstood. Hey, it ain't Old Sparky's fault !
Morty The Official Shop Cat says, "Let me in . . ."
Mort likes his motocross bike stand I got for him to sit on.
Trying to figure out what shaft I'm gonna need for a special project. I've been taking these supplements so I can still kick start all these bikes. My "Sportster Knee" is definitely improving due to exercise and diet.
Pazour Cycle was the shop of Iowa State Dirt Track Motorcycle Champ Bob Pazour. He rode Indians, and many other brands. He won Iowa Championships in 1956 and 1957. I wonder if the building is still there?
Water: The most corrosive substance known to man. After a couple hundred laps of ice riding 6 weekends in a row, this thing is dirty, a bit rusty, and foamy oil still drips from the breather tube. The aluminum is dull, carbon is on everything from the pipes back . . . No loose bolts found yet, but it needs to be fully "gone through" and checked out. I'll hook the brakes back up - and I'm changing the transmission gear from a 18T to a 16T to start running in high gear instead for these shorter tracks like Dubuque Speedway. High is better for the transmission, stronger and less friction, less power robbing . . . the way it was designed.
So I've got this bench top blaster I use . . . and I have a hole bored through my garage wall with a flex hose to attach my Shop Vac (outside) to suck all the dust out of the blaster. When the vacuum is running, this white, exhaust dust cloud is in the air, and the vac is so wore out from all the bead (probably going through the motor) that it rattles and is REALLY LOUD ! The neighbors probably think I got some kind of meth-making operation going on over there . . . and they keep their distance.
Parts "on deck" to be blasted . . along with a bunch of mis-matched pistons Randy gave me to see if any are salvageable to use? A couple are old Dytch stroker pistons !
