best fuel/premix for drr 50 and up

[badcummins59]

I heard that with pump fuel you get inconsistancy in the jetting so I'd like to stay with race fuel.

What do you recommend for fuel and premix?

also any starter jetting for it? running a 21pwk on my 2011 50.

If you can find a 95 octane race gas at the local dealer,that works very well in the 50cc.
The problem is most places do not keep it.
If your area has a import hot rod shop that is your best bet.
Amsoil premix
Jets I dont wanna say exact numbers to try,, the 21 carbs are so silly I have had a 105 all the way to a 120 same engine different 21 carb
But with that said you will be in that range for the main.
Pilot range is 35 to 45 normally
Needle second groove up
I really dont like the 21 carb
But we do have to run it

Ok thanks. Is it true that you guys have cvt tuning classes?

Go on G-Forces web site.. They have a very good cvt page..

If you get the chance. Take one of Rich's CVT classes. It is well worth it.
