What Premix And Ratio Do You Run In Your Ossa's?

Featured Replies

My 2013 factory 300 is coming in on Wednesday the manual is with it.

I'd like to have the fuel

ready to go when I get the bike.

Is there a specific oil that Ossa recommends, or can I use

the same Maxima K2 that I use in my Sherco?

What ratios are you guys running?

Tnx.

I'm currently running 40cc oil in 5 litres of petrol which is about 125:1 (when your running in go with 100:1 - 50cc in 5litres)

I only use the best oil though - Castrol Power 1 - fully synthetic. Here in the UK many use the more widely available oil in a blue and yellow bottle which is vastly inferior. It carbons up and gums up the inside of your engine - well marketed crap !

You're only using half the amount of oil that other 2 strokes use so you can afford the best. Also the main bearings are lubricated from the gearbox oil so you're only lubricating the main bearing (which is directly in line of the incoming fuel/oil mix) and the cylinder bore/piston. Keep on top of the gearbox oil changes.

If you're worried - remove the exhaust front pipe - you can then see the piston with a torch and wipe your finger on the piston and see how oily it is with 125:1 - you'll be surprised.

Great bike - keep on top of the rear suspension link bushes, they don't last long but they are as cheap as chips so you can afford to replace them regularly. Tip - get them from your local bearing suppliers - SKF part numbers are usually stamped on to the outside.
