2-stroke mixture

hey all,

what ratio and oil are the 2-stroke guys on here running?

I am running the Motul 800 off road that came with the bike. Mine seems to like 3 oz per gallon, easy to mix. 42:1 and with the stock jetting and the Q exhaust at around 600 - 800 ft and temps in the 50s to 60s Fahrenheit it is spot on with a 1/2 turn on the air screw with minimal spooge.

I have always run 50:1 with any synthetic oil

Thanks gents.

That is what I would be running also, but with the Q pipe I was slightly rich off the bottom even with an air screw adjustment so I figured I would try leaning the fuel a tad bit and it was close to perfect. I have a feeling that when it gets hotter I will have to get a smaller pilot and drop the needle or run a high quality inexpensive semi synth like Lucas at 32:1. I know the mantra, don't correct jetting with your mixture, but over the years it is what a lot of us have done. It takes a lot less time and hassle to add more oil in the afternoon that carry and switch out jets.

The richer the mix the leaner the fuel, if you run a 32:1 mix the bike will run leaner and you will get lots of spooge, the oil doesn't burn as a fuel but takes the place of it

Read your manual.

Recommended ratio is 1.6% and its enough unless you want to produce more smoke.

You may go up to 2%, Tired with mine when new but didn't like it (more smoke, more time to 'clear' its throat from cold).

BTW, std pilot jet is 35.

2% is 50:1, 1.6% would be a richer mix, for trail riding I would say 50:1 is fine unless there are wide open sections where you have the RPM's higher.

When I would go to the faster areas I would mix at 40:1, but never had any issues at 50:1.

Dirtbird, your bike would smoke more at 2% than at 1.6%? OR is that is just the way I read it.
