After using this forum for a bit for info i have noticed that the answer to most problems is 'higher octane fuel' at first i ignored it.
I thought how the hell is this going to fix my back firing, warming up problems, bad ideling and a rougth riding

I was about to book my bike in the garage for them to have a proper look at it and on the way there i needed fuel and remembered what has been said so put some in .................... i never had to take it the garage after that

It has made a huge difference, fixed all the problems i had and improved the bikes performance in general.

Good News! I was just wondering what different octane levels do they normally sell over there in the UK? Over here at least down in Arkansas we normally have 3 choices of fuel to chose from 87, 89, or 91 octane I have seen some 85 octane in colorado, and every once in a while some 92 octane at some stores. I normally Run 87 in my Bandit, but it would probably run better on the higher octane.

My B12 won't hardly run on high octane. I loaned it to a buddy one day and he brought it back full of high octane. He thought he was doing me a favor but it really chummed up the works until I ran through it.

These bike generally dont need high octane. Only if you've been doing some high compression piston replacement do you really need any higher. That being said some bikes do need to have one step up on the octane scale (89) from time to time as all engines are different. Also when the bike gets older and more soot deposits on the inside of the head, you may need to go one up on the octane scale because the deposits have created slightly higher compression and may cause detonation. Are you sure you just didn't replace some bad gas with new?

I have read articles saying that unless your engine is modified, adding higher octane gas is not worth it. I have tried both higher octane gas and lower and noticed no differences at all. If it works better for you then go for it.

If you run an ignition advance on a stock engine, you will need premium gas. If the bike is completly stock, I would say to run what Suzuki recommends, regular.

I run regular (87 octane) on my jetted B6 with ignition advancer and have had no problems with pinging. There have been many discussions on this site about octane. My belief is that "freshness" is more important than octane. Gasoline has a very short shelf life and degrades quickly. Try to fill up an a busy, high volume gas station to make sure you're not getting old stuff thats gone bad, absorbed water, etc.

I run a 5* advancer on a stock engine (well, Dale's Stage II jet kit) and it does fine on regular.

I'm running the timing advancer and the stage 1 kit and 87 is what the bike wants.

I dont have a clue why it has made it run so much better but to test it i went back to regular and all my problems came back with it so iam sticking with super unleaded which is octane 97 over here (England)

One thing about High Octane, the higher the octane the lower the ignition temps and can cause carbon to build up in the engine. Most aftermarket engine cleaners work in part by raising the ignition temps to burn off the deposits. So using this logic, higher octain is actually not good for lower compression engins, choose the lowest octain that gives you acceptable performance.

I'm with you bro, anything less than 96 octane and my moded B6, it pings its little brains out, and is generally very unhappy with the world.
Ok advanced ignition and aftermarket midpipe and can, tweaked carbs and K & N filter.
However compression is stock cams are stock, I find it hard to beleive that carbon has raised the compression as the bike runs long distances and runs clean, and the engine is now 120 thousand kilometers old and it has never changed form the day I bought it. I think it has more to do with the way the motor was run in. Run them in fast and hard, and they run like that for life. A footnote to this, the minster HAD (please note the word HAD) a 87 honda cbr600 supersport, that if you should even point a premium unleaded pump at it it would run like shyte for a month.
Yet the ZRX also hates regular unleaded, and will return 80 k's to 100 k's less per tank of fuel out on the highway, and in the city, it coughs and again is very unhappy with the world, but on premium its happy as a pig in shyte. Yet the manufacture says run regular.
So back to my theory, again. If it runs shyte on regular and its been to the shop and everything checks out ok, run it on premium, if that cures all the woes, you have the answer, run it on premium. if you still have problems you have problems, its that simple.

Here here Mick.

As I've said many times before in the debate on fuel,

"the only thing Premium seems to do is empty my wallet faster"

....I don't notice any appreciable difference in performance or economy, except that some premium fuels make it hard to start.... the Treasurers M750 on the other hand will run like shyte if you use anything less than premium, loves Vortex....

To paraphrase Red, use the lowest octane you can without having problems......

Mind you I do find that it also depends on WHERE you get your fuel, some of the small country servo's have some of the worst fuel you can get also filling up your tank just after they've filled up theirs isn't a good idea either...
