Trinket Arduino Dynamic Timing Video + Spring Break Update

So, first, the video you've all been wanting to seeeeeeee... the DYNAMIC DIGITAL IGNITION video!!! huzzah! Sexy curves in action:

monitoring the switching pin on the microcontroller to make sure it isn't going to be fried.

board prototype idea

This happened the day before I left for spring break and was glorious. Spring break packin:

I'm working on making this ignition more physically robust and perhaps making a debut of it at Inverness. I still have a little to do moped wise though and a lot to do car wise. Old Yeller has to be gone through entirely for road worthiness as the 2 inch hitch on that car could likely haul both bikes. If it can't, I may be inclined to take brownie since I know his service record better and he has many "new" parts. Brownie needs the new sport exhaust package installed from IPD though, so that has to happen tomorrow if it ever shows up. I'd have to throw a bike on the roof though, and that coupled with is 4 speed transmission = terrible gas mileage.

Spring break wrenching 2014 first up was the maxi. I'll get some new pics of it posted some time before I leave maybe, but I added some chrome trim to the frame and it is CLASSY. Wiring is cleaned up, painted and detailed flywheel and finished up all the little stuff (like shortening the speedo cable). This bike is done for a while till it gets a reed kit. ZA50 geared at 21x37 and has so far been GPS'd at 51mph with all stock parts.

Next up was the derbi. Lots to do to this little guy. I made a puller for the clutch... hardware was $3 total. Had the parts lying around since last time I was home ;) Then I raised the exhaust port a little and resealed the engine (no leaks, knocks on wood). Thought I needed new crank seals but turns out pre-mix was just running down the electrical into the stator (no airfilter) sweet. For some reason, the condenser all the sudden quit working though - like instantly. I was out riding and got a GPS speed of 41 out of it and then it started backfiring. Points arced like a beast, so I did a condenser and all was well. Nothing changed timing wise it just up and quit. Weird/LAME. Can't wait to put digital ignition systems on all my bikes. I also made a CVT cover because the thing throws junk ALL over the frame. GPS speed of 41 was with lots of airleaks, so I'm leaning it out now that it's sealed up.

The weather in Inverness will be glorious. I can't wait. High today was like 40 and last night it was flurrying.

Mid January Stuff

So, it's mid January. I've come back the past two weekends to work on stuff. Most of my time was consumed with my sister's car, during which time all the family's Volvos were in the driveway of my Dad's house on a rare occasion... Last time this happened it was dark and photo opportunity was terrible. Got some great shots this time.

When I got back to my own things, I reassembled the CB125 with new rings and fixed the old tach cable with a junkyard speedo cable. The tach works, but the 125 still hits a wall at 55mph. It runs better, but still like crap. New cylinder is in order this summer (or maybe an overbore piston?). I just drilled out the old fitting that went in the case, and soldered the "new" cable in. I pulled it out of some 70's muscle car.

 

Then before I left last weekend, I welded a new bung on the maxi!!! Woooo! Doesn't leak either! This weekend, I got to finish it up and take it for a ride. It was glorious. Check out the top speed... I've got 4mph left to find... 55 was my old all time top speed and I even touched 60 (indicated) once. That was with my homoet 6p though and I'm running an estoril chamber now. I also almost got hit in my dad's neighborhood because some idiot was not paying attention and almost hit me head on while I was sitting still at a stop sign...

Not pictured, is finalized baffle mounting for the Derbi, time spent building a failed concept design I've been working on and some aluminum welding I did with my lincoln pro-mig 135 (it's pretty horrible, but usable). Took forever playing with the settings to get it to feed without jamming and I'm welding with ArCO2 AND it's filthy aluminum (I did scrub it with a wire brush at least) but it's promising... the spraying thing really was weird... because there's no puddle and HOLY ballz batman, turn the wire feed speed up to 11!

Currently contemplating getting a second bottle for aluminum shielding and a second hose/gun/etc so I can swap quickly between steel and aluminum. I have a feeling I'll be wanting to swap often enough I won't be wanting to change liners.

Since the derbi.... Winter Break Update #2

I put expansion cones in the dumb derpi and now it does 40. Still has only one broken brake lever - need to fix that. Maybe later. Got dio 1500 clutch springs coming for it as well as the nuts I need to make a puller. So, I need to source a stronger contra and throw those springs in. Then I need to do some porting. Hmmmmm.

Did the flame trap on Brownie (no biggie) and ended up needing to do replace the alternator tensioner, water pump (leaking) and re-plumb the oil pressure sending unit on Old Yeller.

Worked on the cb125 and 100 some. Welded a replacement for the broken tank mount on the 100, washed and waxed the tank and did fork oil on both bikes. The cb125 was pretty hilarious.

Did a blow down test on the 125 and it leaked really bad past the rings. Took it apart and guess what? The rings were in a billion pieces. Hard to believe this bike still did 55mph before I tore it down and didn't grenade. The rings were such small pieces, I can't believe they didn't turn and ruin the cylinder. Amazing. I've left the cylinder head sitting with ATF in the dome for about 36 hours now - none has leaked. Thinking this things gonna be a ripper when I get it slapped back together.

The vespa does stoppies now too. So I did that (still have a speedo too woot), re-re-reinforced the exhaust and repaired the rear rack. Reinstalled the foot pegs and STILL having wheel clearance issues with the footpegs installed. Whatever. I'll deal with that tomorrow. I started a thread to deal with the partial pad contact on the vespa brakes and my concern to their longevity. Terry Dean mentioned cutting the pads so they don't hit each other when they wear and I end up with no brakes - good call Terry. Apparently it's fine to run them like this though.

Used my torch for the first time to cut the bracket out for the Vespa disk brake conversion. Worked great. Wish the hoses had gotten here in time to do the exhaust work on the derbi. That would have been fun. My dad came outside to watch and make sure I didn't blow myself up. He also took some video. I'll get that posted later.

Still left to do this break is plenty. Here's the list:

Brownie

• Stud nuts for the A/C compressor (a couple are missing)
• Rear pads
• Tidy the electrical
• Install and wire fog lights

• Stronger contra spring
• new lens for the headlight

Maxi

• re-assemble top end (raided for metric coupling nuts)
• reinforce frame
• braze/weld bung onto tank so I don't have to use stoppers anymore

CB125

• Reassemble engine
• minimize massive head oil leak
• ride

CB100

• reinforce and clear coat side covers
• inspect before 300mi trip to Desirae's place

Swinger 1

• Go through the engine...
• Considering throwing an E50 on there

Prima

• get that piece of junk fixed and sell it for cheap

Puchonda

• swap SL70 parts in for manual clutch and mechanical advance ignition
• make frame repairs
• increase exhaust backpressure

Old Yeller - the 242

Meet Old Yeller. The 1978 242. I acquired this car from an old time Volvo mechanic in Georgia. Old Yeller is a fully functioning road worthy car that was driven under his own power back to Nashville.

Some favorite tidbits...

• 4 speed manual transmission with overdrive
• working/charged R-12 A/C system dead as of Summer '14
• 700 series turbo mags
• R-sport gauges 100-200 series
• alleged original paint
• mechanical fuel injection
• breakerless vacuum advance ignition
• no power steering (from factory)
