Hi all,
I've just received a new exhaust for my derbi senda. The exhaust is a gianelli. My setup is a new airsal 70cc cast iron and 21mm carb. Stock airbox. Does anyone run this setup? I'm after an idea on where to start the jetting please?
Also, are there any Derbi or moped meets in Northern France, Belgium or the Netherlands? I'd like to visit
Many thanks
Paul

Hi, 120/115 is a plausible place to start, probably to big but just go down from there. I've got a 72,4cc with 17.5mm carb with a 98mm jet (to big). Before that a 80cc-24mm carb and jetsize 130mm with powerfilter. So 120 should be a safe

Don't know of any meetings at the moment here in the Netherlands but surely there will be a few this spring/summer

I gave it the first start today and it was very smokey. I'm running 33:1 using e5 fuel and putoline mx9. I'm going to be using this bike for light offorad
