Hi guys. I just recently baught a new 28mm Mikuni TM for my Derbi senda.
I have on the derbi an athena 70cc kit and a leo vince exaust.
Is the carb too big for my setup? do you think I can get it to work good?

For your setup, 28mm is too big.. I used a 21mm with a similar setup.

You can get it to work no doubt about it. But if you bought a stock mikuni carburettor. You probably need to change all the jets in it. And it aint easy to find the correct needle jet, needle.

So for your economic change to a prejetted carburettor. I't makes life's alot easier =)

A 28mm is way too big for that setup, will shift the power up the rpm range. Making the band pretty short.

that's if you can get it to run right
