Fuel

Can anyone tell me if they use additive in the fuel for a Z1b

Thanks

[Steve R]

No you dont need to they were designed to run on unleaded from the start and they are low enough compression ratio to not need high octane

Thanks Steve

I've got some Avgas from a friend. It's 100 octane. I've not tried it yet as I'm a bit concerned it might cause damage to a standard Z1000 engine.

Any thoughts?

Cheers

ive tryed 102 high octain fuel in my z900a4 that they sold at the local bp station where i live . I MUST SAY BEST TEN POUNDS IVE SPENT ONLY GOT ABOUT 35 MILES FOR MY TEN POUNDS BUT GREAT FUN WOULD,NT USE IT AGAIN BECAUSE IT DID SEEM TO SMOKE ABIT AFTER GAVE IT A GOOD THRASSING .BUT ITS STILL RUNING OKAY .SO AFTER THAT I WENT HOME AND GOT MY OTHER BIKE OUT OF THE GARAGE TRYED IT AGAIN BUT DID,NT NOTICE ANY CHANGE SO I NEVER USED IT AGAIN THIS WAS ON A KAWASAKI ZX 636

I have just spent some time researching Avgas.

It is short for Aviation Gasoline, which is used primarily in piston engined aircraft, but also gets used in motor racing. It is of a higher octane than the crap we buy from the forecourts because it has Tetra-ethyl lead added as an octane enhancer and for it's anti-knock characteristics.

Whilst our engines will run on the low octane shit served up at the pumps as regular or premium unleaded, it isn't actually particularly good for them as they are relatively high compression engines and were originally designed to run on a higher octane fuel.

I always run Super unleaded (commonly 98 RON)

A modern bike will not benefit from higher octane fuels as it was designed to run on low octane petrol, but our classics most certainly were not designed to run 95 RON petrol. I'll keep my eyes open for some 102 RON fuel which appears only to sold by BP. As for a bike smoking after running on high octane fuel - I think that probably has more to do with you thrashing the arse off the poor girl, rather than any damage caused by the fuel. The higher octane fuel is actually kinder to the engine if it is a high compression engine. Low octane fuel will cause our engines to pink or knock.

When I first got my Z1B, I put a 'FuelCat' in the tank, as these are supposed to increase the octane rating, improve combustion efficiency and stop petrol degeneration in the tank and carbs (it worked on my Laverda Jota).
I ended up removing it, as the bike ran rougher, and the plugs soon ended up getting a crusty deposit on them, especially if only pootling around.

I'm just about ready to re-fuel so I'll try the Avgas. I normally use super unleaded but at a fiver for 5 litres of Avgas it's worth a shot!!!

As I have said before on a thread about petrol .....
If you put a teaspoon of 3 in 1 oil in the tank when you fill up it sorts all the problems out ... stops all the shit accumulating in the tank & carbs ...
AND it dont cause any exhaust smoke

Plus the fact it lubes the carb slides
