• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

regular gas

Where have I been...:doh:

I've got an 06 610 TE (carb) and have always used premium gas in it. A buddy caused me to wonder if it really needed premium...I just assumed it did because I've never had a bike that didn't. Dumb time to look now since the bike is 2+ years old and gas prices are coming down. But...looked at the manual specifically for gas requirements and it just says, "unleaded fuel"...nothing about octane ratings.

So...y'all run regular...without issue?

I have used regular a few times but that was due to no premium being available. I noticed no negitive preformace issues.
 
With 11 to 1 compression ratio, I would not use regular unless I had to, and then I would be easy on it until I could get some higher octane gas in it. IMHO :)Ken
 
I have to say I was wondering the same thing but the manual do say just unleaded so that’s what I’ve been using

So that’s the consensus among 610 owners, you guys are running the higher grades?
Think I read somewhere that US grades are higher then Europeans to begin with, is that a factor at all?
:excuseme:

Yes.

http://en.wikipedia.org/wiki/Octane_rating

The minimum octane rating for my 2006 TE250 is R.O.N. 98 on page 50 of my owners manual.

This has been discussed many times on other parts of the web and I am quite hopeful that this thread will easily be found again. So if anyone has any links to previous threads (I can't find any) or wants to put in their 2 cents (yet again) now would be a great time to post up.

Hopefully this thread won't get lost! :thumbsup:
 
As pointed out, detonation is a bad thing. This is when the compression forces of the piston cycle or worse yet crud in cylinder is left burning, heats then sets off the fuel air mixture ahead of the desired timing cycle.

Octane rating in simple terms is a measure at which the fuel can be compressed before it heats by friction and detonates. If you have detonation move up a rating. Running a higher octane rating does not equal more power. It's a mater of knock. Got knock...move up. No knock, try a lower rating.

Keep in mind not all motors are created equally. Higher compression motors require a higher octane to safe guard against pre-detonation. Remember your science classes?..compression of anything results in heat. More compression equals more heat. Diesel engines rely entirely on heat during the compression cycle and have very high compression.

On the pre-injected TE's running anything less than super at 92 octane rating (USA) is going to result in some knocking. Manual specifies 98. The injected models may have a sensor to retard timing.. I don't know. Some "other brands" have selectable timing settings to allow running fuel in say 3rd world countires.

All the above also applies to your daily driver car. People who use super unleaded to baby their car "just because" are generally just wasting money.
 
how bad is gas in 3rd world countries? in particular central america...

would it really screw my bike to run a gallon here and a gallon there of crappy gas? 2006 sm610.

at higher elevations it would be less harmfull. sea level, ouch!
 
is there anything that can be done about this? like having along some octane booster or something for when you're only option is crappy low octane fuel?

i have ridden in places in central america where its bad, very bad ..kills the power in your bike noticeably plus its hard to get used to some guy hand pumping petrol from a rusty 40 gallon drum :eek:..

but hire bikes were invented for people who want to wreck someone elses machine....

as a side note ..once i had the pads replaced somewhere ..what they did was get old car pads and cut the pad material into the shape of my front pads..bond it somehow to the metal backing and you were good to go..except obviously my hand cant generate the pressure a car brake servo can ...this i noticed on the first steep descent:doh:

With the gas shortage several of us added in it in our Ducatis (1098) with good results. Also, with electronic ignition it did fine on regular in an emergency...better than pushing it. Just held back on the fun lever a bit...:thumbsup:

Where? My manual definitely is silent on the octane issue? And I promise...my glasses are on and clean!:thumbsup:

You can follow that link to see how that translates to USA (MON) ratings.
 
The manual states 98 RON, which is equivalent to about 94 Pump Octane here in the states. (RON + MON)/2 = Pump Octane Number. Typically the mix would be about 96 RON and 88 MON which yields the 92 Pump Octane. According to George (Uptite), you can help yourself a little if you run some leaded race gas (114 Sunoco) in these bikes. Raises the octane and helps with the valves. Mix 4 gal. premium to 1 gal race gas.
