Dellorto 21 phbg DS jets

[kyledude]

I bought the Dellorto 21 ds for my 2008 Yamaha zuma

Wonder exactly what jets I need to tune the carb I tried stock and it get hot fairly quick

What sizes are the jets for this carb and do I need main and pilot jets?





Athenna 70cc big bore kit
Dellorto 21 ds
Stock air box
Malossi "multivar" Variator Minarelli Kit
Yasuni R exhaust
MICHELIN Bopper tires
NCY clutch springs 1500


Thank you for any help

The DS takes 5mm Dellorto jets.
You are best buying a selection of jets. www.scootertuning.ca/en/carburettors/5052-main-jet-set-stage6-dellorto-5mm.html

You might be okay with the stock pilot jet. I would try it and see first before ordering some.
You do know the DS has no vacuum feed?

Thank you. It might be the lack of fuel cuz it starts up but gets hot quick. Maybe I need a different carb that will work with my setup.

What ever carb you buy will need setting up. They are a good carb so you should be able to make it work.
What temperature is it getting up to? Full throttle or part throttle?
