These 28mm Keihin Carburettors are used by nearly ALL of the best Trials riders. The Gas Gas Pro is fitted with a 26mm dellorto carb from standard which are fine for 99% of riders and are real easy to jet etc. but the Keihin being 2mm bigger gives a smoother power at the bottom and the gives a real clean mid to top end performance. When jetted correctly the top end revs are increased dramatically.
