Woo Hoo. :dance:
Thursday...Partly sunny and breezy. Highs in the upper 60s. Southwest winds 15 to 20 mph with gusts up to 35 mph.

[N8YX]

Riding a bike to work, George?

I am today. :yes:

[w2amr]

No, but I'll be out and about this afternoon on the Harley.

[K7SGJ]

No, but I'll be out and about this afternoon on the Harley.

If it turns out to be a long ride, stop by.

If it turns out to be a long ride, stop by.I'll be sure to pack a lunch.

We're going mountain biking after work...if I can get 'DSG's bike back together.

[KG4CGC]

Do you jet for different climates and altitudes?

After my bike ride, I decided to give the treadmill a break , and do my mile in the neighborhood. Very nice afternoon.:agree:

[N8YX]

Should have clarified: Mountain pedal​ biking. If I was riding a carbureted dirt bike, I would be looking into jet changes if a drastic change in elevation or temperature was a possibility.

[KG4CGC]

I keep forgetting, I'm the only guy running a carb in 2012.

The mouth of the carb. Knife edged the butterfly. Shimmed the jet needle. Rejet the slow jet, settled on #42 from #35 and the main to #88 from #75. This is a CV carb based on the old SU design but with a Japanese twist.

I hope we jump into summer mode early this year. Since this winter was a total wimp out hopefully this summer will kick some ass. But somehow I suspect the summer will be a wash out too.

Someone took a shot at the tuba player?

[N8YX]

We did 18mi on the mountain bikes last evening - a little less than half of it in darkness, with my new hub dynamo light illuminating the way. 'DSG got both of our existing Planet Bike 'Blaze' (2w version) installed on her bike and I took one of the 1w units to run alongside the generator light. The dynamo unit (Supernova E3 Triple) is pretty darn bright at speed and has a fairly wide beam...but the Planet Bike units illuminated the near sections of the trail a bit better than the Supernova. Not bad for a light that's 1/5 the price, either.

The hot tip is to use a pair of Li-Zinc rechargeables in these lights. They put out 1.6v instead of 1.5...doesn't sound like much but that extra 0.1v basically doubles the output in lumens. We get about 2-3 hours run-time on 'high' with a full charge and 5-6h on 'low' mode. Flash mode (which we never use) would probably see run-times of 12+ hours with the Li-Zinc cells.

Oh shitski, the honda started running like crap yesterday. I changed the fuel filter and drained the float bowels of the carbs, no change. The plugs have 10k on them and are over 5 years old. I'll change them out next, but it sounds like a fuel problem.

[N8YX]

Do you add stabilizer to your Honda's fuel before putting it up for the winter, George?

If not, you may have some varnish build-up in the slow jets.

I would have said the same thing based on mileage alone ☺

I also add some carb/FI cleaner with every fill up. I stopped at the Honda dealer today and picked up 4 new sparkers, put them in , and it's running fine now. Hope it stays that way, Taking the carbs off of this thing is a major PITA.

[N8YX]

Glad to see this was an easy fix, but 10k mi on a set of plugs seems a little on the low side. Did NJ reformulate their gasoline for spring? That used to be a huge PITA for me when I rode an SOHC 750...seemed like I was fouling a set per week.

Did you eventually lean out the mix? Certain additives will cause a rich condition where as others will lean.

What fixed it was a change to the pilots, change to the jet needles...and stop running Marathon-brand fuel. When I finally switched to BP I put upwards of 50k on that bike without a hiccup...and with the same set of plugs, albeit cleaned and gapped every year. Ignition was via a Martek trigger (instead of points) and Accel coils...but 80kv still wasn't enough to fire through that slop-o-lene.

This is a DOHC engine, not that it that it makes much of a difference.
I think the gas has stayed the same this year.
No Fouling, If anything the plugs look like the engine is a bit on the lean side.

Isn't there a way to get the gas out of the carberator and keep new gas from flowing in from the tank ? I know on my small motorbike there is a trap valve between the tank and the carb. When the switch (valve) is off no gas can reach the carb or the engine.

Although I think the valve is closed the gas in my tank has probably turned into solid varnish by now. I haven;t driven it in years because it's in my parents garage and my Dad has it buried under a ton of wood, boards, and assorted garage junk. I can't even see the thing much less get near it. I am going to have to empty out whatever remnants of what was once gas is in the tank and then wash out the tank if I plan to drive it ever again.

[w2amr]

That, and drain your carb's float bowl. Or bowls. I have to take the carbs off the 450 Suzuki , and clean the float bowls and needle valves. All the gas evaporated and left brown crud behind. Fortunately, the gas tank is clean and rust free.

Yes, I am familiar with the term. Years ago when I worked in an industrial lab we had these large carboys containg corrosive acids. There was a tap near the bottom of each carboy on which was fitted a simple petcock followed by a hose. To turn the flow of acid on/off was just a simple matter of switching the petcock on or off. A lot safer than trying to tip and pour from a huge container of concentrated acid.

The petcock on my old motorbike is exactly as described in your link. It has three positions, on/off/reserve. I never understood what the "reserve" position did because there was only one gas tank. Now I understand. It is to pull fuel from the "reserve portion" (bottom) of the tank. Too bad I didn't know this the time I was running out of gas and wound up pushing the bike home. Had I switched to reserve there probably would have been enough gas to make the trip home.

Ah well, now I know. :)

Petcocks on modern Chinese bikes are vacuum actuated. You'll see a line coming from the tank to your petcock. A line from your petcock to the fuel air mixing device, usually a carburetor and another line leading to the motor somewhere, sometimes near the carb, this is the vacuum line.
Back in the olden tymes, you had to handle your petcock manually. You had to touch it as it had a handle or ''tang'' on it. Your petcock tang could be turned 45º to switch the flow of fuel on and off.
Sometimes, there are many questions on the petcock tang.

My 450 Suzuki has a set up like that. Looks like vacuum from the engine opens a diaphragm inside the petcock, which lets the gas flow.

Often, a faulty petcock is to blame for sudden fuel problems.

CVT, okay, thanks. Makes sense on a ride like that.

[KG4CGC]

Very tunable.

[w2amr]

I got the carbs off yesterday, and pulled the float bowls. What gas that was left in there turned green and stinks to high heaven. There is also about 1/4" of thick crud stuck to the bottom of the bowls and floats. I also notice one of the needle valves is stuck open , and both jets are blocked. I am so glad I took the time to check this out.

What are you going to soak it in the start the initial breakdown of the crud?

[w2amr]

What are you going to soak it in the start the initial breakdown of the crud?I took it apart and cleaned everything with gum cutter, then brake clean, then spray nine, then blow dry. Careful with the gum cutter, it attacks rubber/plastic.

[N8YX]

Careful with the gum cutter, it attacks rubber/plastic.
Especially true with certain runs of Keihin/Mikuni carbs. The slide locator pins were made of plastic and strong carb cleaners will dissolve them.

[KG4CGC]

Gaskets and seals can be revived and or restored from accidental exposure to gum cutter. Immediately dunk it in water to stop the chemicals then dry and put a bit of Vaseline™ on it. Usually, it will return to it's original shape. Note, doesn't do a thing on hard plastics.

I took it apart and cleaned everything with gum cutter, then brake clean, then spray nine, then blow dry. Careful with the gum cutter, it attacks rubber/plastic.

For stubborn and small parts like jets and internal circuits, a lethal mixture of spray carb cleaner, B-12 Chemtool, gasoline and automatic transmission fluid makes for an effective overnight soaking solution. Look for the non pressurized carb cleaner liquid.
