TECH: Magneto

I build my own magnetos from parts.  Start with a good Fairbanks Morse body and go from there.  They usually work great (strong spark, etc.) . . . however, since it's the most "misunderstood" aspect of an engine build (compared to setting valves, carb jetting, etc.) you naturally suspect it's the problem/reason your bike won't start.  Whenever I think my magneto is the problem, I send it to Rudy Calin in Minnesota (Rebuilt Mags) to get it checked out . . .

 Rudy uses shrink tube to insulate the points spring.  The spring comes really close to the base plate, or screw heads sometimes . . . just good insurance against arcing or grounding. 
Rudy also replaced my condenser with the slightly snappier FM SXY2433 mfd.  I looked through my box of mag parts, and found I already had one . . . by Colt Industries (who purchased Fairbanks Morse Company)  Rudy also recharged my magnets !  Old Sparky Comes Alive !

(see my condenser output TECH chart soon)
I prefer these black caps with the "lightning bolt" or the old-time factory-made FM magneto caps.  The clear caps are handy to view your points breaking(or arcing), but they can allow sunlight to heat up condensation and moisture inside - also, I think they're just plastic?  Rudy has really nice & heavy cover gaskets available too . . . www.rebuiltmags.com

WR Idler Gear and Stud

 

2 engine building enthusiasts (me and my dad) have worked on this for the last nights to get this Idler Gear Stud (and Gear) in the correct location for gear mesh, etc.  What a sucker it was . . . and now we need to make a sharp, steel, center punch deal to fit over the end of the idler shaft, and a solid aluminum plug installed in the gear cover, and "center punch" the cover, then we know where to bore the bushing perfectly - so the stud is supported in the cover too . . . It Still Ain't Done Yet !

Draggin'

I might have to cut off my splined Left footpeg mount? (I see there's is gone)
 
I keep dragging my left side on the ice . . . First my brake(took that off), then my stock peg mount(took that off), then my new higher peg(took that off too).  Now I stiffened the forks, and Bake brought me over another set of stiffer tubes and springs if this don't work . . . These guys(above) use the same peg I have now, with those pull-back bars?  If I can go half as good as Carroll or George sometime - I'll be more than happy.

1950 California Panhead


Kerry still enjoys old-school blogs (like this one) and he sent me a couple pics of his vintage rides.  He bought his '50 blue panhead(basket case) back in '76, and still enjoys shining it up for the Born Free Shows, or whatever else is happenin' around Cali.  For some it's just a fad - others it's a way of life.  Old custom Harleys never die, they just get rebuilt and carried on from generation to generation, each one doin' their own custom touches.  Each owner personalizing their ride, from daily riders to show stoppers.  As it looks here, Kerry couldn't make up his mind which he wanted - so he builds his bikes to do both  . . . Show-n-Go !

If A Sportster Is What You Want . . . (Ebay)

Some early Ironheads are poppin' up on Ebay lately.  Quite a variety . . . Check out this radical lil' stroker digger.  Performance is what you need.  It would cost a lot of money to build this today - and with some work - a real show stopper and tire smoker.  Custom frame, brakes, struts, Performance Machine parts . . . this thing is bad ass.  Little baby blue Victory.



Now if you're into dark and doom - Want something with a bit more death.  This far out prism diamond in the rough is for you.  Full Diggerization !


You got to be a tough stud to go crankin' on this bitch.  This bike IS pretty killer.  Lot's of work went into this back in the day.  A really nice paint job with murals and themes is what it needs now.  If you came riding up on this, all packed - Respect you will receive. 
You say both these motorcycles are just too gnarly for you????? How about this bone stock barn find with plenty of rust and aluminum disease???



I've traveled many miles on an early ironhead such as this.  These are actually great touring motorcycles (especially on 2 lane back roads).  I fitted mine with a 22T transmission sprocket.  I can run 70 if needed - but it prefers about 62mph.  Loaded.  Bags full with a big duffle bag for back support on the buddy seat.  Tuck down behind the compact windshield during heavy rain or high winds.  Your body will be ready to get off before you ever need fuel.  If this is just too much baggage for you to handle?  The next "stocker" is the one you need !



 A big 1000cc with optional aluminum rims.  This is the Neil Diamond of Harley-Davidson Sportsters.  The XLH (with electric start) and the hardest seat ever fitted to a stock ironhead.  This seat will make you leap off around 60 miles.  It's also one of the hottest seats, able to reach soaring temps in full sun.  It'll burn you, right through your denims.  The plastic gauge covers get so foggy you won't care anymore about revs or speed, you'll be enjoying life so much on this factory gold beauty.  Place your bids now. 


Gremlins Do Exist

I can't figure this thing out.  It just starts hard.  Everything is spot on (ignition timing, carb, intake, cam's timed, adjusted accelerator pump, wire continuity, new spark plugs, valves set . . . etc) Now I removed the magneto(sent it to my magneto guy to check it out) and added a distributor(timer), battery and coil, and it acts the same.  I need to get it running and take it for a good ride around the neighborhood, maybe some slow speed backroads - get some carbon built up . . . that always helps it seems.  I run 8.5 std compression, 4 1/2" stroke, new Super E, Andrews AB, and have tried 3 different types of spark plugs.  Starts best cold, enrichener up, couple shots of fuel, throttle closed, timing full advanced.  It takes about 5-10 kicks.  After it runs to warm up - then I can't get it to start.  Valves aren't tight, has spark, has fuel, had the timing every which way . . . Fart.  I hate to start changing "big stuff" . . . since it should start and run fairly decent with about any combination, especially this combination.  Hey, at least it looks kinda cool?!  Best thing is just keep checking things, and not get too excited.  Maybe I should ship this out to Kerry in Placerville?  He knows how to make a panhead run . . .

Left-Side Dual Carburetors



It makes sense to me . . . have the carbs-on-the-left.  Less intake runner and more direct shot of fuel and air to the valves.  But then you have less time for the fuel to atomize, turn to an oxygen rich mixture of gases ready to explode.  Huh.  I'll have to ask Kevin Baas how his dual-carb panhead(carbs off the left) performed?  I never heard him complain about it.  The long intake manifold runner on a panhead, I always figured kinda worked like a tunnel ram on a V8.  A larger amount of gas and air getting all mixed and sucked in for a huge explosion.  The more gas and air, the more power. 

Spearfish Creek, So. Dakota

This photo was almost 20 years ago.  I was in Sturgis for an Ironworks Magazine photo shoot.  I was so excited that week.  It was like I finally hit the "big time" with a bike I built(with dad) soon to be in a magazine!  I rode to Spearfish that day on backroads, rode the canyon, waded in creeks, it was hot.  One of the most fun days I've ever had on a motorcycle.

1953 BSA Gold Star


Yesterday, I was gassing up my pickup at the local station with my bike in the back, when a guy approached and asked what year my bike was...?  I proudly said, "It's a 1952, K Model Harley."  He said his dad has(or had) a 1953 BSA Gold Star racer.  I thought, hey cool.  I went to say something about my Harley, but he interrupted to tell me how great British bikes are . . .  bla bla bla bla bla . . . it pretty much went downhill from there.  Oh, well.

Update . . .

This week I pulled the primary, drained the oil, cleaned out my clutch baskets, installed new Raybestos clutch plates (they were soaked with oil), added 15% stiffer clutch springs, relocated my left foot peg and shortened it, adjusted my forks, and checked the plugs (which were about perfect color).  Both cylinders running evenly.  I'll add some more foam under the tank, check all the bolts - and I should be good for a few more laps.  Zero degrees this weekend !  Maybe I'll wear my electric socks with 2 D batteries . . . ?

1952 KR

The first KR came equipped with the same capacity tank as the 1952K street bike.  This particular KR appears to have the higher capacity 6+ quart oil tank, and smooth dome primary cover.  No brakes of coarse. 

Perfect Ice Conditions

Despite a slipping clutch, I still had a blast riding last Sunday.  The extra slippage forced you to practice better throttle control, and work on corner speed.  The 19" front didn't work as good as a 21".  The bike was pushing and sliding - and I'm not using any brakes either . . . it makes it more interesting to me.  I rode for about 4 hours, 3 tanks of gas and made about 70 laps.  If a guy had this bike back in '52 . . . but 65 years later, still pretty damn fun.  Not too many K Models riding ice this year(Pretty sore on Monday)

Albert Burns

Shrimp Burns was the fastest motorcycle racer of his time,
however, his time was short . . .
b.1898-d.1921
 

Duane Allman

Did I hear this correct?  On the same day . . . he bought a Sportster and a helmet.  Cut the chin strap off the helmet.  Left the dealership in Macon, Georgia riding the bike with his friends(and girlfriend) following in a car.  He was runnin' along at a fairly good speed, and clipped a wrecker-type truck and crashed pretty heavy.  Allman really didn't look that busted up, but he had some bad internal injuries.  They got him to the hospital, but it was too late.

Clete from Old Dude Vintage . . . 84D

I see on the web, Clete from Old Dude Parts had passed away.  I talked with him (I think) at Davenport before I knew who he was . . .  Then I talked with him over the phone many times at Old Dude, when I needed parts and had questions.  I believe his son (who was at Davenport this year) and helped me, sold me some special fasteners, will keep the company going.  A great ol' guy who I never knew was a racer himself . . . and a really good one.  I could have picked his brain on all types of WR, KR and XR stuff . . . gone forever.  Go Fast / Turn Left - RIP Clete.
