26mm Jetex ???

[#1GP200]

Evening all, someone told me of a dealer who was modifying jetex carbs, turning them into 26mm and replacing all the jets with dellorto ones. Cant find out who, been all over the internet, anyone know who it is??

Cheers for the replies lads, both companies do them. Will be on the phone next week.

Taking a jetex (or 22mm dellorto) out to 26mm causes leakage past the slide and inconsistent mixture due to slide flutter. That's why Arthur Francis told me never to go bigger than 24mm which works really well. Get any engineer to ream the carb out to 24mm and increase the main jet to suit. Start with 200 slide and atomiser.
