JOSH, I JUST WENT TO BR8ECS IN MY 2000 SRX WITH RACE BOX AND NEEDLES RAISED TO RICHEST SETTING. SLED BEEN GIV,EN ME SOME STARTING ISSUES WITH BR9ECS. WE ALSO BEEN USEING THEM IN A 600 SRX WERE RUNNING ON GRASS WITH NO ISSUES. 3:16 (yammie tony)

interesting tony. the br8ecs is a hotter plug than stock. i guy would probably have problems of long periods of wot, like on a lake.
 
KNOW I WOULD NOT RECOMEND 8,s FOR THE REGULAR RIDER. ALTHOUGH I THINK WHEN THE ORIGINAL 98 SRX CAME OUT, SOME DID HAVE BR8ECS. 3:16 (yammie tony)
 
From my memory...LOL!
When the 98 SRXs were first introduced they came with and were speced to have BR10ECS plugs but they found some fouling issues so most riders changed to the "hotter" BR9ECS and as we know that became the standard plug for the later models.

The NGK BR9ECS has a conical shape base,
which can allow a short center electrode and a
short ground electrode compared to the formerly
used NGK BR9ES.

The main benefits of this spark plug are:
– Reduction of pre-ignition and detonation by dissipating heat more efficiently via electrodes and conical shape base.

– Shorter ground electrode preventing vibration breakage.

IMPORTANT NOTICE: Do not try to adjust electrode
gap. This spark plug is already gapped at factory.
Because of the ground electrode shape, trying
to adjust the gap through the usual feeler
gauge method would not be very accurate.
 
Here is one to fuel the fire...I used to run my stock SRX with stock pipes with 87 octane running 146.3 pto, 145, 145 (Leaner than leanest year of jetting) mains with BR9ES plugs across the board. I am not at all recommending this but the engine made it through somehow. Did LOTS and LOTS of lake racing with it for mile plus pulls too. haha
 
I have run 87 octane in my SRX but only because I had no choice,fuel stops at outfitter lodges in the back woods,and as far as burning down the engine as long as your not running wot across a lake or what not you can get by until you get to a town with a station able to provide supreme.It doesn't hurt to carry octane boost with you too but there are many different schools of thought as to weather it works or not and also what brand works,I usually carry a couple of bottles of Pennzoil brand stuff I get at Canadian Tire.It comes in a metal can and not plastic which from what I can gather is the true test of a good octane boost product or not.You be the judge.

that is what |I heard also that the ecs helps with denotation issues.Why wouldn't people run what Yamaha recomends for the sleds.

Because theyre cheap mofos and they will scrimp on every penny at the risk of going KABOOM!!

Wondering what damage is done if any, if regular octane fuel is used in sled. When in Canada, not sure if I can always obtain premium fuel.

If rebuilding your motor after every season is on your things to do list then I'd say go for it.
 
I've put a lot of miles on my sled all over Ontario and I found it just to be the opposite in the Northern part.A lot of places only had the higher octane fuel.Don't forget a lot of these places depend on the sledders for income in the winter.They're not going to sell you crap fuel and take a chance of loosing the winter business.Word gets around fast about bad sh*t.

P.S.For our southern friends.This is not the last frontier.We everything here that you have there and better beer to boot.
 
snowsnake - I have riden at least 12-15 thousand miles in quebec touring from the southern areas where all the name brand fuel stations are to extreme as far as you can travel north on trails. But I have to say when we go north and I'm buying gas outa that tank behind the bar its not premium. I pay premium price for the worst fuel money can buy. God bless Canada. I love that trail system!!!
 
Quebec is another country altogether.Just ask them,they'll tell you.All I can go by is my own experience.I've got approx. 25,000 klm's or 15,000 miles on the Viper(ya I know they're not as fast or as sensitve to poor fuel) and never had a problem getting Super.My motor has never been apart either.

P.S. Only ever ridden in Ontario.Got good trails right out the back door(usually)so I've never felt the need to add to the cost of a sled trip by trailering.Not to mention paying for another trail pass.
 
I'm jealous that you trails of that quality right out your door. With the bad economy we have suspended trips to Quebec.
 
I didn't ride at all last year due to a knee operation and haven't done a big trip for at least 3 years.My nephew and I used to take the 2nd week of Feb. every year, leave Sat. morn and land back home the next Sat. or Sun.The old Viper got tooo many miles on it to take off into Northern Ont.You can ride for 2 or 3 hours and not see any civilization tto speak of.Don't see a new sled landing any time soon either.My big trip days may be over.Not getting any younger.
 
Buddies 01 srx has 8000 mi in N Ontario, most likely has permium fuel in the tank less than 1/2 the time. We have had more issues with bad fuel than not being able to get premium in Ontario. I did rebuild the srx last fall, no detonation, and pistons were in spec, put new ones in as I already had them. Personally have seen 6 sleds go down with bad fuel but the beer is better, thank goodness.
