cmc 2011

[Fred Hink]

The dates for next years Canyonlands Motor Classic have been updated on the CMC web site.  This gathering of dual sport riders (mostly KLR) is always the first weekend after Memorial Day.  So the rally for 2011 will be June 2 - 5.  Mark your calendars and hope to see you all there.  http://www.angelfire.com/ut/moab/cmc.html Fred www.arrowheadmotorsports.com

I have a 16T front sprocket on my 07 and have always had to run in 4th gear below 50mph. In 5th gear,  If I let the RPMs get below 3K, the engine would start lugging. Since switching from regular to premium, 11/2 tanks ago, the KLR will now cruise at 2.5K rpm . I can now ride those 40-45mph roads in 5th gear. It is my understanding that premium gas burns slower than regular. Maybe this explains why I"m getting smoother runnimg at low rpm? Craig

Had you tried sea foam (Carb Cleaner) before? Prem. often has more cleanners in it.   I do like prem. over th others while many try to say makes No differance I have always SEEN a diff., it stands out best in small cc bikes like 1-200's where you can see increased speed & power. My truck NEEDS mid grade (89) at least, or while idleing I can hear the diff.. Travel Safe! Travel Well!

My 09 also has a 16t sprocket and I weigh about 270lbs. It will pull without lugging in 5th till about 40 mph. Any lower will lug the engine and requires downshifting. I have never tried Premium gas though.   Bob 09     To: dsn_klr650@yahoogroups.com; ckahleer@... From: nomad59@...

If you are running in 5th gear, under 3,000 RPM, and accelerating, you are lugging the engine. That said, I am guilty of this from time to time - especially during low speed cruising, as Craig described below The use of higher octane fuel can smooth out the power pulses at lower RPMs but you'd be better off if you downshifted to 4th gear under these conditions, regardless of the fuel you are using. If you really want to observe the effect of fuel on the KLR, find some old gasoline - you know, like that stuff that's still in the Chevy truck you parked out back 5 years ago, thinking to yourself "I'll get to this in a couple weeks". Don't ask me how I know this....... Mike Craig Kahler wrote:

I just put my first tank of premium in yesterday.  I have noticed a noise if I go by a wall or anything that will reflect the sound back to the rider while adding power.  It does sound like denotation.  Its kinda a ching sound, whatever that is.  It may not be but thats why I'm tryin premium this time.  I checked the frame bolts and everything seems tight.  Of course there is always a chance I'm hearing things but I don't think so.    Gary Souderton, Pa.     To: DSN_KLR650@yahoogroups.com From: mike21b@...

I agree totally with the first statement. Premium gas has added cleaning agents in it. Every 5th tank I use premium and it keeps the system clean. The extra octane is not required in a stock KLR 650.

I am amazed to learn that anyone in the group is not running the best fuel they can get in the usa. I am currently in Peru, mostly playing! Yesterday in the jungle I was checking out some outboards- Mercroid 4 cycles. They are having trouble with the oil ring turning to the bottom of the cyl.- not a problem with the KLR. Also they are burning headgaskets. Turns out the wrench is removing the thermostats! The biggest problem is the fuel. They are running cheapest fuel they can get- all they can get in the jungle! 80 octane! If they had been doing this in the usa the engines would have already been trash, of course they are Merc's already! I told him to find NAPTHA and mix in the fuel, or moth balls if he has tweezers. Down here there is NO Ethanol trash, and there is still lead! This is the only reason these engines are still alive at all. Tomorrow I will be trying to trash a KTM 530 in the desert. For that we have 98 octane, leaded, NO Ethanol!!! Yahoo! Of course it is $9.00+/ gal. For those of you near enough to an airport in the us, get the avgas! it's 104 oct & low lead. Perfect stuff for the klr. I run it in my Scorpa, KLR KTM...all the toyz in the us garage. Weed wacker too.

High octane gas is a great think for bikes that need it. I had a Guzzi that liked to ping on 92 pump gas if you pressed it, but ran marvelously on 100 octane avgas. or 108 race gas. But I always had the option of dual plugging and setting the spark back to run on regular. On a couple of occasions, in really hot, muggy weather, I have thought I detected some pinging with my KLR. 92 octane may have smoothed it out some, but the effect was subtle, to say the least. Other than that, I have never observed that my KLR ran any better on premium. My KTM does like hi-test, and does not like to run over 80 on regular, whereas on premium it will pull its red line in top easily. In Copper Canyon, it is almost impossible to find any higher octane than 81. My DR650, all the KLRs, and everything else seemed quite happy on that. Of course, the elevation may have been a factor.

I can’t sit back and read this without further comment… and a war of words may ensue – but: “Premium” Fuel is merely higher octane fuel. It does NOT clean your engine better. It does NOT prolong the life of your engine. It does NOT save money. Last and definitely not least, your KLR will NEVER produce more power via higher octane fuel. It will VERY likely produce LESS power.

 

I doubt if I will convert anyone (and that’s fine) but there are only 2 reasons to use “Premium” (higher octane) gas:

 

1)    If your manual says you should use it – for example, a finely tuned, high compression sports car with knock sensors and / or engine management system that adjusts the ignition timing for maximum performance. (and even then, many have proven, after 100,000 miles or more, that many of the PREMIUM FUEL ONLY vehicles actually run faster and longer when regular is used)

 

2)    If your engine suffers from detonation, pinging, or knocking due to the uncontrolled combustion (which would be abnormal in any engine, but an indicator that you need higher octane fuel).

 

The KLR does not fit either of the above categories. It never fits the first example, but it could fit the second. If you don’t have one of the above conditions, you are wasting your money on fuel. You probably are doing no harm, but you are spending money unnecessarily.

 

Avgas -- All people who attain their pilot’s license must know this – it is required knowledge to pass your tests: Avgas (100LL) is made for airplanes. It does NOT give your KLR higher performance, nor does it make it run better, nor does it clean it. If anything, using 100LL can actually DAMAGE the engine of a KLR. 100LL is made for airplanes, not motorcycles. If you are running your KLR at 12,000 feet altitude at a steady 75-90% throttle for long periods of time, 100LL might be appropriate – but who rides like that up there? (And your bike better be jetted very lean for these conditions). 100LL is also NOT 100 Octane when it is measured by the same methods pump gas is – it’s more like 96 Octane. Higher octane, yes. Better for your KLR, no.

 

Back to pump fuel. Yes, some manufacturers advertise that their Premium Fuels contain additives that clean your engine. They do – but so does their “Regular”! Some ads go so far as to claim that Premium contains MORE of those additives. It might – but the difference between what’s in “Regular” vs. what is in “Premium” is so small that it makes virtually no difference. With each gallon of Premium you buy, it simply increases the profit for the oil companies. That’s why they advertise it: you buy it, they make more money.

 

(And, no, I am not one of those Big Oil conspiracy subscribers)

 

Want to give a treat your engine via the fuel tank? Add Seafoam per the instructions on the can. It’s cheaper than using Premium gas (when used per instructions), and it will do a much better job of cleaning and preserving the fuel.

Only one of the above needs Premium: the Audi. It performs better with it.

 

One other recommends premium: The SHO. However, years of experience with the Yamaha built DOHC 3.2 liter V-8 has shown that it is not needed. No one uses it, and drag strip numbers indicate lower trap times for those who use high octane, then switch to “regular” with the SAME CAR. …It goes FASTER!

 

It is almost universally known among the ZRX riders that this bike runs fine (actually better) when 87 octane is used.

 

The KLR engine is a low compression, low power, low tech engine and probably knows no difference between Premium and Regular. But it’s a superb bike and that’s why we have them and love them.

 

OK, my flame suit is on……

I am amazed to learn that anyone in the group is not running the best fuel they can get in the usa. I am currently in Peru, mostly playing! Yesterday in the jungle I was checking out some outboards- Mercroid 4 cycles. They are having trouble with the oil ring turning to the bottom of the cyl.- not a problem with the KLR. Also they are burning headgaskets. Turns out the wrench is removing the thermostats! The biggest problem is the fuel. They are running cheapest fuel they can get- all they can get in the jungle! 80 octane! If they had been doing this in the usa the engines would have already been trash, of course they are Merc's already! I told him to find NAPTHA and mix in the fuel, or moth balls if he has tweezers. Down here there is NO Ethanol trash, and there is still lead! This is the only reason these engines are still alive at all. Tomorrow I will be trying to trash a KTM 530 in the desert. For that we have 98 octane, leaded, NO Ethanol!!! Yahoo! Of course it is $9.00+/ gal. For those of you near enough to an airport in the us, get the avgas! it's 104 oct & low lead. Perfect stuff for the klr. I run it in my Scorpa, KLR KTM...all the toyz in the us garage. Weed wacker too. --- In DSN_KLR650%40yahoogroups.com, Gary Thacker wrote:

if I go by a wall or anything that will reflect the sound back to the rider while adding power. It does sound like denotation. Its kinda a ching sound, whatever that is. It may not be but thats why I'm tryin premium this time. I checked the frame bolts and everything seems tight. Of course there is always a chance I'm hearing things but I don't think so.

lugging the engine. That said, I am guilty of this from time to time - especially during low speed cruising, as Craig described below

RPMs but you'd be better off if you downshifted to 4th gear under these conditions, regardless of the fuel you are using.

gasoline - you know, like that stuff that's still in the Chevy truck you parked out back 5 years ago, thinking to yourself "I'll get to this in a couple weeks". Don't ask me how I know this.......

gear below 50mph. In 5th gear, If I let the RPMs get below 3K, the engine would start lugging. Since switching from regular to premium, 11/2 tanks ago, the KLR will now cruise at 2.5K rpm . I can now ride those 40-45mph roads in 5th gear.

this explains why I"m getting smoother runnimg at low rpm?
