After lowering the gear ratios, this bike is a joy to ride. Top speed prolly dropped, but low and midrange acceleration greatly improved.

I get to shift to second gear, climbing the steep ramp at work. The hill on the way home is no longer a problem, altho I haven't had to ride in bumper-to-bumber going up that hill.

Received new electrical parts, set to work on bike that I haven't touched in months

It runs, and it runs good! Phew. Although the rear tire seems to be leaking slowly. And the entire thing is rather slow.

I smacked my CDI down on the workbench, and now I have spark!

I tried cranking it over with a socket on my electric drill. Without the plug in, I got a weak looking spark, so I sprayed a little starting fluid in the plug hole, put the plug in and tried to turn it over with the drill.
The cheap socket broke, so I'll get another one tomorrow.

I tried to pedal start it, and my front tube blew out when I let the clutch out. It tore right at the valve stem, so it's tube time too! LOL

At least I feel like I'm making some progress. I ordered all the components to make my own CDIs too. Then I won't have to depend on the cheap Chinese units!

I ordered a bunch of parts to make up for the flaws in my cut rate eBay 4 stroke kit - new engine mount, chain, and wide crank. Added a kickstand and pedals for good measure...

Needing a few odds and ends, and it being a nice day I took the beast out for a ride.. three quarters of the way there it died on me, seems to be getting no spark. Checked the wiring, with and without kill switch. Tried swapping white and black wires. No luck. (I had to switch to running on the white wire a few weeks ago, from the black. It just stopped working for me, but I didn't have a tester for the wire then.)

Anyway, once I got it back to the garage I started poking around. There is continuity on all three wires from the magneto to the CDI. I checked both bikes while I was at it. There is continuity from the ends of the wires to thier connections. On my bike when I check the black wire I get a light (circuit) on nearly every surface in the magneto housing. The white, only at it's connection, same for blue. On the working bike, the difference is that I get a light on nearly every surface with both white and black wires. Curious, that.

I swapped the CDI from my bike over to the other bike, and it fires up and runs, so the CDI is fine. I seem to be getting nothing useful from the magneto with the voltmeter but I admit I may not know enough about what I'm seeing either.

I tinkered with things until I ran out of daylight (and then some). It's supposed to pour rain tomorrow, but I might be able to pull the magneto and see if there's anything there I can do. If not, I may have to find one and put it in and see what that does for me.

Back in the day, Champion plugs were THE plug to use in our SBCs.
...the racer's edge... and all that stuff.

In later years, doing more with the dirtbikes, there was just no better plug for general use than the NGK in the 2 smoke motors of different sizes.

I don't know what it is abt them, but they just performed btr, and longer.

...if oreilly don't have the b6hs, go to the next store! lol


...I always thought the Autolite plugs were a nicer looking product than Champions... so when working on a Ford I always run them. It shouldn't matter.

Now, it seems the only plug that needs attention is the stoopid thing Ford did with their Triton series. jerks

.........
Will rejet my cns again today, another step leaner, and will pull the needle up all the way for starters.
I ran on a long downhill a few days back, when I thought I was in a hurry. Got the biggest r's the engine has ever seen, and it was singing! Sounded very good, and was very smooth with no evidence of vibration increasing.
...I should have kept a proper log of my process re-jetting...

If this new try doesn't make an improvement, I'm gonna switch out to the nt for a while...

I took the plug wire off a 125 hp 2 smoke Boat motor "I like that nic name for 2 stroke btw " & replaced the one I had on the bike. While there "in the boat motor" I noticed 4 CDI's attached to 4 plug wires

There is no way this boat motor will run again My question is will one of these CDI's work on my Bike or do you think it will smoke my Mag.? 1 silly more question On our CDI's the blue wire is hot and the black is a ground correct?

There was 4 plug wires on the 4 CDI's but I scavenged them for various projects. Our CDI is on the far right & little bit smaller I like the blue one it matches my bike color ..almost! Do you guys think it will it work?

It's been raining/drizzling this week, but I still rode my motorized bicycle to work. Sometimes I started off wearing my rain jacket. Or when it started raining, I'd stop, don my jacket and resume my ride.

My co-workers think I'm crazy; they look out the office window and fear the warm rain. I just ride more cautiously, sometimes on the sidewalk.

My newly-fabbed chain tensioner works well. I'm using a slightly grooved ($5 used) polyurethane skateboard wheel, ($1) flat plate, ($2) 11lb spring and a ($1.59) small turnbuckle. My engine chain runs tight/loose/tight/loose. It MIGHT be due to a defective chainring sprocket or freewheel. However, this tensioner solves that issue. The cool thing about the skateboard wheel is that it has a high-performance ABEC-7 bearing, good for thousands of rpms. With the 1" OD engine sprocket, 2.5" OD skateboard wheel and 5:1 transmission, the high-quality bearing is spinning less than 600rpm at the engine's 7,000rpm redline. And instead of a 200lb rider pushing down on four skateboard wheels, there's only an 11lb spring applying pressure on the bearing and chain.

It's so cool, looking down and seeing the chain tensioner in action!

What's even cooler is watching the derailleur in action and listening to a high-performance engine, as the rider shifts gears seven times.

Yesterday, "rush-home traffic" was very heavy and the roads were wet. That steep hill near home was gridlocked, and riding the hill were three kids on modified mopeds. I chose to ride the dirt path on the road's shoulder. With my new gearing, my bike charged up the hill like a dirtbike. Instead of keeping up w/traffic @ 30mph on the flats, I rode into the neighborhood streets at a slower speed. It's a much safer route when it rains.

On the steep ramp at work, my bike charges it like gangbusters. I can shift to second gear before I reach the top. On the other two ramps, I can run them in second gear. At the top of the last ramp, I turn off the engine and coast 200 feet to the bike rack.

The one feature I notice about my new Schwalbe Big Apple 26 x 2.50 tires is that it can roll much farther than the older Armadillo 26 x 1.95 tires.
