Hi all,

Just trying to dial in my set up for my bike.

Px125e (switched to premix--removed autolube).
Dr180 kit
Mazz crank
20mm carb
Sip road two exhaust

Any recommendations on carb set up. Looking for a bit of punch and planning on taking this scoot on a long trip in July.

Thoughts?

Thanks.

I've had success with a Stella with everything you listed. Stella's have reeds vs rotary so your perfect setup will be a little different but start out stock starter, idle jet, drill out the heart in the air filter and 160, BE4, 125. Obviously favor the conservative side of jetting as you'll be pushing it hard on your trip.

Noted. I already have a drilled out air filter.
I think my main stack is currently:
160/be3/115. Plus looks decent with my sito plus pipe. I'm replacing it with the sip exhaust once I receive it.

I can try the 125.

What's your top speed wot? 3/4 throttle?

Thanks.

I'm new to this tuning stuff but with everything I've been reading in here the Jack Stack is the key to start with 140/B5/mj .
