What to expect when running 98?

[Hahn]

Sorry about double post!

too many characters my ass!

Av gas will see a very noticeable rise in power out of your bike but, isn't recommended... unless you want to burn out piston rings etc etc and only have too rebuild your engine later on. Av gas is also leaded, can your bike handle leaded fuel? From memory, and correct me if wrong lead is used to boost octane up to 130 which regular unleaded can only reach 100 (or 98 at the pump). Even "Low lead AV Gas" still contains lead.

I think this classifies for Viffs thread ramble on posting utter absolute shite as if they were facts. What a lot of cowpoos! Seriously. What made you post that? Are you the Stranger incognito just trolling bollocks thinking they are funny or did you believe that rubbish you just posted.

Hmm, you perhaps could have got away with your piss take if not for this gem.

Piss take my ass- its a fact
I gain 10kmh on the hill simply by using 98- and get better range- as your not riding my bike you can speculate allyou like - it me who is on the seat

There is a direct mechanical relationship between your crankshaft and your wheel. For every 1,000 rotations of your crank, your wheel moves around a set number of rotations. This can NOT be changed by fuel alone.

So NO your bike does NOT go faster "for the same engine revolutions" on 98 (fuel being the only change) this is quite impossible.

So YES you are absolutely full of it.

Like I said, correct if wrong, its been a while but.
quote: "The particular mixtures in use today are the same as when they were first developed in the 1950s and 1960s, and therefore the high-octane ratings are achieved by the addition of tetra-ethyl lead (TEL), a highly toxic substance that was phased out for car use in most countries in the late 20th century.

Avgas is currently available in several grades with differing maximum lead concentrations. Since TEL is a rather expensive additive, a minimum amount of it is typically added to the fuel to bring it up to the required octane rating so actual concentrations are often lower than the maximum."

For what ever shitipeadias worth....
But hey what ever...

Maybe your talking about the first part, go and thrash an engine on av gas... see how long it lasts. That said, lead is the biggest issue. cat converters just love it.

The bit I objected to as drivel was . . .

Av gas will see a very noticeable rise in power out of your bike but, isn't recommended... unless you want to burn out piston rings etc etc and only have too rebuild your engine later on. Av gas is also leaded, can your bike handle leaded fuel?. . .

If I was shirty it was because you presented it as some sort of fact, sorry if I was short but it is indeed utter bollocks.

There are a zillion race bikes around the world running on Av Gas (for better or worse, that's another story), but typically they will not show any increase in power in std form. That said if a bike is running a high compression ratio (most aren't, with exceptions of some european brands like BMW & Triumph) & they have modern ECUs they will optimise the ignition timing to suit. Many (most) probably won't.

But the biggest load of cobblers was that some how it will 'burn out your rings etc" Please explain by what mechanism this is possible? You have the whole internet at your disposal.

. . .
. . ., go and thrash an engine on av gas... see how long it lasts.. .

Gee I've been running my racebikes (highly modified to take the advantage of higher octane) for nigh on 20 years. They wear as quickly on Av as they did when we had to run on pump gas.

. . .
. . ., go and thrash an engine on av gas... see how long it lasts.. .

By what mechanism please? Does it burn hot enough to 'burn the rings? Is it worse for friction so it wears them out? Worse than pump gas?

Go ahead, please explain. The silence will be deathly. . .

And I don't mean by referring to some someone talking on an internet forum.

And I'm not talking about damage the lead will cause to your Cadillac converter (that's the part that turns your sportbike into a gas guzzling American luxury car, you read it here).

Or admit & quietly retract your statement please.

ahh thats the bit i was missing, although i did say efi will adjust....

As for the other, your right. thrashing on any fuel will be the same.
changing compression ratios, (hotting up engines...) that will result in faster wear...

Sorry had to get up especially early this morning

1, cheap fuel goes in (well reletively).
2, bike runs.
3, smile happens.
4, smile ends when out of fuel so I repeat from 1.

Just run the bike, don't get too heated about it (excuse the pun) and enjoy the nice weather.

My bike has the lowest tech engine of all so I am prepared to be shot down but then I don't care.

FZR1000 has fixed ignition timing and not very high compression.98 is to high.
mine runs well on 95 and it is the next year up (exup) with 12;1 compression.
Yours will be 11.3;1 and even further retarded so 91 will most likely deliver the same or more horses.
Lower octaine has a faster flash time and older bikes with ignition retarded will run better on low octaine fuel.

FZR1000 does not have an ignition plate that can be turned to advance and there is no way to install an off centre key lock plate either.Pickup comes from a fixed position.It is possible to do housing work then construct an adjustable plate but the gains outway the work involved.
A better mod is adjustable cam sprockets and getting valve timing correct as being 22 years old the cam chain will be stretched and valve timing will be out.

can your bike handle leaded fuel?

Well yes, my blue lovely is not a modern bike.

As for the Mobil shit I get nothing but grief so I stay well away from it.

Interesting comment. We dont get a hell of a choice in this town for petrol providers. Mobil or Shell. I almost never go into the Mobil, reasons too many to name, but there have been a couple of times. Why do you say no to Mobil?

But the biggest load of cobblers was that some how it will 'burn out your rings etc"

Well that I am pleased to read. It has been many years since I have been around bikes running on Av gas, but it was and probably is still very common. I dont remember any particular issues with the engines running it either.

My comment was actually a bit tongue in cheek really. The thread is about what happens when you run higher octane gas. I have noticed a performance gain between 91 and 96. I wondered if more is better or not?

I have a 1991 inline 4 engine with no fancy fuel management system. I have one carb per cylinder fed by vacuum from the fuel tank. Well the carbs suck and the tank delivers.

Fuel/mileage increases will be the next discovery.

have tried all the octanes with the daytona and the results were as on a 17.5 litre tank and a top open road speed of 110kph

98=341kms

95=262kms

91=227kms

triumph also recommends that the bike is running a mimumin of 95 octane on standard factory settings
so I run 98 when ever possible

That's bloody interesting Barry. I've only run the S3 on 95-98 and found I get slightly better economy on 95. Also, throttle response seems to be a little less urgent when using 98. Still, it ain't no Daytona!

Must be the fairings!
