just bought my self a 2007 sherco 290 to replace my 2002 sherco 290..

just wondering a few things..

whats the fuel / 2 stroke mixture?

how do i tell that it really is a 290 and not a 250?

on the frame i see it has a picture of a fuel tank and says 98 on it, i presume this means 98 ron fuel? (super unleaded?)

cheers

Hi,

No different on the mix, many use 80:1 ratio.

Look at the motor number, below and aft of the carb, should start awth SH290 -----.

Super unleaded, yes at 98 ron

ok cheers

my 2002 sherco i was running normal 95 ron fuel and for the mix i was doing... 5 liters petrol 100ml oil... i think thats 50:1?

They run fine on 95 but sometimes, if going down the road for example they can start to knock using 98 helps.

You oil amount is correct, if your using a good quality fully synthectic 2 stroke oil you can run a lower ratio, I run mine at 75:1

I think it helps prevent the exhaust getting bunged up with oil.
