could anyone tell me best setup on oil(full or semi synthetic)and ratio and jetting as running rich.thanks

ok then

which oil should i use semi or full synthetic?

i am currently running at 60:1 on putoline mx7 full synthetic.

any replies for this one?

There are about as many opinions as there are oils.

I run full synth at 80:1

Many run 100:1 successfully.

60:1 is on the rich side, but if you burn out the muffler now and again...

As for jetting, 33 and 126 should do it.

USA Team Sherco uses full synthetic Maxima oil mixed 80:1, here in the US most bikes seem to run well on a pilot anywhere from 33 - 36 with a main jet of 118 - 122. It all depends on the bike and the altitude.

Your location in the world may dictate different jets. Talk to a local rider and find out what works for him, you may find his set-up to be perfect and again you may have to adjust for your bike/riding style. The jets that Charlie mentioned are a good starting place.

Where are you????

i am in south east england - mud!

have tried running at leaner mix 65/70:1 earlier but my steed seemed to run

a bit hotter and not be as responsive ,when it has been running richer it pulls alot stronger.i am trying to find a happy medium between not being too rich and power being ok.

this is what i am running-

main 126

pilot 33

needle clip 2nd from top

air screw 31/2 turns out

super unleaded

ngk vx plug and cap

all other carb settings are std for that year according to sherco website.

Jetting is right use ultimate fuel and fully synthetic at 80:1, clip leave standard and pilot jet adjust to conditions/bike.

Should be fine NgkBP5es or VX equivalent.

ok dabster, will try that this sunday.

thanks.

have now settled on castrol tts at 70:1 with a 126 main and 34 pilot.

seems to be ok,but it was wet and muddy so i may go back to a 33 pilot,

we shall see.also now running castrol tts- bike runs cleaner.much better than putoline mx7.the castrol is not as thick as the mx7 and it also mixes easier.

i used to use tts by gospel back in my 2stroke mx days.always said it was the best 2 stroke you can get.
