Mine does 280 before htting the bottom of the tank. Excpt when it decides to hydrolock & i'm forced to waste good petrol & drain good oil

(Like today).

shouldnt be hydro'ing. You running a cr9 in it or somthing.

Hydrolock has absolutely nothing todo with spark plugs. In my case the float valves stuck open and petrol filling the cylinder to the brim. Doesn't go anywhere & is a pain in the arse to rectify.

why dont you either turn off the fuel when it's parked, or putting a vacuum operated fuel switch on the line from the tank?

I didnt say it did. Just the two most common problems with kiwi motorcyclists are running the wrong fuel/plugs and not fixing their carb problems. If it wasnt one, it would be the other

All sounds simple, but I have a fuel pump which lets gravity feed petrol through slowly when off and a fuel tap with only 3 settings - on, on or on. One day I should get round to fixing it properly. Getting some POR-15 tomorrow to clean out the tank to stop all the rust crap from keeping the float valves blocked open.

Could you get away with running a CBR or an RG on this stuff?

I'd rather quench my thirst with gasoline

I could be wrong, but in a 250, you don't need to fuss too much over what petrol you use. My regime is 2 tanks of 91 for every 1 tank of 98, and I never run my tank dry.

**GNR** · 22nd November 2005, 19:50

I think my fuel tap has the 2 on on on settings, must be something in the mc19s,
I run 91, never have a problem, i get 200km, and thats 9L to fill her up, so prob about 288km per tank

isnt "race gas" expired aviation gas, so it 100LL ?? spose it depends on what "race gas" you buy/use
