I don't like this guy. He's calling my friends names and he's seems like someone who has more opinions that KMs in the saddle.

However, he has a point about SS. That being: it's a forum that skews heavily toward older, whiter, more conservative, uber-patriot kinds of folks who like to grind their axes loudly in public. It's not always a welcoming place for those who don't fit the aforementioned profile.

But I've made more friends (I hope) than enemies over there and their wrenching advice has been invaluable.

Just my $.02.

[QUOTE=Andrew2;21203853]Hey Bob,
that's a great idea.How much power does it draw?.I'm thinking it might be good for mid winter camping depending on whether it will flatten my aux car battery.

Cheers
Andrew

P.S. while people keep biting trollers keep fishing...just a thought[/QUOTE

Doesn't seem to affect my stock battery though it's usually running. It has a 30 min or a 45 min timer setting also.
Keep in mind i'm a know nothing "newer" Ural owner...

AceRph for the win! Now back to our regularly scheduled programming...

So now that this thread is back on track after being brought back from the dead, how about we start putting some tech talk in it?

I just bought a Husky TR650, my first fuel injected, liquid cooled bike. The CafeHusky forum is all abuzz talking about it requiring premium fuel. As does the Ural, now might be a prudent time to have that discussion.

My thoughts on the subject. I live in the Southern US, and Summers are hot. I definitely see the value in running high octane fuel in the Summer since it ignites at a lower temperature. However, I don't see a performance difference between the fuels the rest of the year, so I run regular.

That said, I stay away from Ethanol enriched fuel as much as possible though.

Oh no!

We shouldn't broach the controversial subject of fuel, never mind lubricants!
Do the newer Urals really call for high octane?
There is the same amount of energy in a gallon of 87 as in a gallon of 93.
Octane is only about detonation. High compression motors require high octane to prevent pre-detonation. (There are also higher concentrations of additives in premium fuel, mostly detergents.)

May want to think about that some more.

Quote:
Octane rating is a measure of grace under pressure: how evenly a gasoline will burn under difficult conditions, like hard acceleration. Ideally, the vaporized gasoline inside an engine’s cylinder burns by the propagation of a wave of flame, ignited by the cylinder’s spark plug. This allows a smooth transfer of power to the engine’s crankshaft and the car’s wheels. But at higher pressures or temperatures, small pockets of gasoline vapor can prematurely explode, or self-ignite, creating a distinctive “knocking” sound, as well as potentially destructive shock waves.

Gasoline with a higher octane rating does not self-ignite easily, and burns more evenly than lower-octane fuel under harsh conditions, resisting detonation and knocking.

I run 87 all year with no problems. The Ural runs great.

I've only owned mine for a month, and have yet to achieve "running great"!
But I'm working on it...

She started running rough yesterday coughing, backfiring until she quit and wouldn't start. Luckily I have a tow rope in the trunk.
Of all the possible scenarios, I'm going to check valve clearances this weekend.

water in the carb bowls?

I run premium but not for the octane; it is the only grade that has no ethanol, which degrades rapidly and since my uRal is at the cottage and not ridden all the time, I want to know it will run when I need it.

From the 2012 Ural owner's manual

Compression ratio 8.6 :1
Fuel 91 octane premium unleaded gasoline

That 91 octane unleaded is a ridiculousness recommendation for a 8.6 : 1 engine.

BTW, I've been running up to 10% Ethanol since it was introduced and have never had a problem with it. I am NOT advocating Ethanol just stating my experience.

Now that the tax credit on Ethanol has gone away, maybe corn based Ethanol will go away. Would be interesting to get an Ethanol test kit and see how much is in a gallon on of up to 10%.

we have ethanol in all grades of gas around here

it's an oxygenate, a replacement of MTBE, meant to reduce smog and maintain a healthier ozone

besides, we've grown accustomed to high fructose corn syrup in Everything!



water, huh?
maybe. worth a turn of the bowl-drain screws anyway...

thanks


another boring, gas related topic - ethanol is similar to isopropyl alcohol (dry gas) in that it forms molecular bonds to water leading to phase separation or a suspension of water in the lower levels of a tank rather than allowing the heavier water to accumulate at the very bottom of the tank. This bond can be broken, somewhat, by mixing new fuel into the tank reducing to water/fuel ratio but, blah, blah, blah, etc., etc.

I have experienced similar issues to what you describe and draining the carbs resolved it.

Second question, have you re-jetted it?

If factory stock, the jets are not optimal.
