The last tank I got of NJ's best crapola 87 fuel is giving me a sizzeling sound under load between 5-6k RPMs. Bumped it up to 93 octane tonight. Temps around 40f, will now be colder, low 20s.

Fingers crossed the super cures it.

Anyone else notice preignition/detonation signs/sounds?

I was getting some detonation I switched tp 100 percent gas no ethaol that seems to have fixed it

 

[JerzKawiKid]

Nj gas definitely isn't the best, don't settle for the cheap places like wawa or "speedy gas"

We've noticed that, even in our cars and trucks. And Especially in the bikes..

Hmmmm.. I am running just fine here on 87 w/ 10% ethanol, I only go to quality gas stations though..

 

[Ghost_Rida]

Guess you just got a bad batch. But ethanol is not too great for any car or bike in general. It has a higher burning rate so it leaves residues behind and slowly causes corrosion.

 

[old3]

I use a good source that fuels my race bikes too. I'll check to see if they just got a new winter blend or something. The 93 seems to have just about eliminated it for now.

so i was on a long ride today. stop to fill up on 91 it ran good till i stopped at a light about 5 miles away and my ninja stared knocking. any one have this problem ?

 

[cbzdel]

knocking how?? has it stopped??? Or did you just keep riding like that?

 

[old3]

Describe the sound and RPMs if you can please.

Mine sounds like a very light, tinny sound. Kinda hard to describe, the sound of hot metal being hit by cold liquid drops maybe, like a sizzle.

 

[SPARTAN300]

it was kinda like a hard knock. i was gonna pull over and turn it off but i was far from home and was scared it wont turn back on. so i stared driving and it went away and has not came back.

i got my no cut frame sliders today too and wanna put them on but i dont know if it will void warranty

no-cut sliders from kawasaki i assume? i highly doubt their own product would void their own bike's warranty

the quality of your gas can really make a difference. shell, exxon, sunoco, etc. all are good name brands. the non-name brands usually just blend every other manufactures left overs together, making crappy gasoline. (coming from a kid that works at two gas stations) (new jersey)

 

[Woomba]

I've read that it is a bad idea to fill up shortly after or while a tanker is filling up the underground gas tanks. This is because it stirs up any water or sediments that were sitting at the bottom of the tanks. So you have a good chance of putting those same impurities in your tank until the tanks are allowed to settle.

dreaded ethanol.

 

[dkw12002]

No knocking, but I get a little detonation right after I downshift. Nothing like the Ninja 650r. I don't think it is due to octane though. Actually, they lowered the compression in the 300 from the 250r.

 

[kiwi]

Yea they did lower the compression ratio. Can't remember what it is though. We have 91, 95, and 98 in New Zealand. I usually just use 91. Do you think running 98 will help at all or will I just be wasting money?

I have a feeling my noises might be the cat expanding or overheating at those RPMs now. Looking into that further.

 

[cbzdel]

Wow sounds like several people are having issues.. Not good....

 

[Lienmarine]

I don't know, i'm on my second tank of 87 with no problems at all. I think part if it might be people who don't really know what "pinging" or "knocking" sounds like from too low of octane. When you've never heard it, it's easy to think you're hearing it. I've had a few turbo and high compression cars, and i'm not getting anything fron the 300 on 87.
