2005 Ninja 250 Carburetor size

SV Racing Parts · August 22nd, 2018, 10:57 PM

Hey everyone. It looks like the 2008 - 2012 Ninja 250R Carb size is 30mm. Is it correct that the 2005 Ninja 250 Carb size is 32mm? And if so is it a bolt on mod for the 2008 - 2012 Ninja 250R. Thanks for all help,

Enjoy the ride, and best regards,
Blair

Pretty sure 08-12 is 28mm and pre-gen is 30mm

Will the 30mm 2005 Carbs bolt right up to the 2008 - 2012 model 250R??

Sorry, my mistake, they are both 30mm. The fuel-injected version of 2008-12 250 had 28mm throttle bodies.

No bolt-on upgrades will improve intake side as major restriction is in head. Putting bigger mouth on funnel will not flow any faster as outlet nozzle will still be same size.
