Hi all, I have ordered a new oil pump but It wont be here until Monday is there anyone that can recommend a 2 stroke oil to petrol mix ratio please for my malaguti f15 Firefox so I can use It to get to work just until my pump turns up.

Thanks

Read your manual. Two stroke oil is much better than it used to be.

Hi

Short term safe bodge is probably to got for 33>1 or 25>1

Remember to jet up to suit.

All the best

I would aire on the side of caution and go for the ratio with a bit more oil to fuel , a bit of extra smoke to keep your piston happy

Wot ratio would you recommend waynerck

On my trials bike I use a silkolene premix at 50 to 1, like others say though I'd go 30 to 1 I think, overdoing it will be smoke and plug fouling at the worst.

Remember though oil in the fuel mix means less petrol = leaner mixture= overheating damage possible, upjet it or risk it, choice is yours, if you decide to not upjet then I suggest avoiding thrashing it.

Does the op understand 'Up Jetting'? (Tamperfering with the carburettor jets to change the air fuel ratio/s.) It may be alien language for some.

The scooter has already been up jetted by me, I emailed malaguti themselves to ask what stock size main jet was and reply of them stated #58-60 and I have up jetted to a #68 main jet, the only problem now is the right oil to petrol mix ratio.

Hi,
just go for 33/1 thats always my default pre-mix setting.
its also easier to measure out.
its translates to around 100ml of fuel to 3ml of 2t oil or a litre of fuel to 30ml of 2t oil.

cheers,
GAZ

So 33>1 is ok for a 2 stroke liquid cooled scooter Gaz

Aww no way can I balls the scooter up by using premix, though it would of been ok, I will use the ratio mentioned in earlier post.

1 quick question, once i receive my new oil pump do I have to do any sort of timing when putting the stator and fly wheel back on or can I just be fitted back to the bike without and pissing about,

Thanks for all your help everyone Very Happy

Stuff can run at 100:1 these days, but if you mix in at 30:1 you can't go far wrong!

I have no idea with scooters but if anyone had suggested I ran any of my RD's, GT's or YDS7 on premix I would have had a heart attack.

Get the bus till your pump arrives.

My petrol pump came today, was wondering do I have to do any sort of timing once i have fitted it and put the stator and fly wheel back on, or can I just put it all back together without any problems.

Haha sorry my oil pump I meant to say my stupidity got the better of me

Hi

Not come across a 2 stroke with a pump that needs to be timed up. But if you have moved the stator then you might need to retime the ignition timing.

You will likely have to bleed the pump through to make sure there is no air in the pipes / pump.

All the best

I have put a permanent pen mark on the stator and fly wheel and also had the piston at the top of the cylinder before I removed pump so would I be able to just put it all back together and match up the pen mark
