THE HEADER PIPES NEED TO HAVE SOME SILICONE SEALANT APPLIED , ALSO A SMEAR INSIDE THE FLANGES. JUST ORDINAIRY CLEAR SILICONE SEALANT LIKE YOU WOULD USE AROUND A BATH OR WINDOW FRAME. IT WILL WITHSTAND THE TEMPERATURE NO PROBLEM ,AND WILL STOP UNSIGHTLY DRIBBLES OF OIL FROM THE FLANGES.

DO YOU NEED MY BIKE TO MAKE THEM ON??

NO, I HAVE COMPLETE BIKES HERE SO I CAN GUARANTEE A PERFECT FIT.

DO I NEED TO REJET??

ALMOST CERTAINLY YES! 2 STROKES NEED CORRECT JETTING TO RUN PROPERLY AND INCORRECT JETTING CAN CAUSE SEIZURE AND ENGINE DAMAGE. I ALWAYS RECCOMEND THAT YOU CHECK THE JETTING ON YOUR BIKE WHEN FITTING EXPANSION CHAMBERS. UNFORTUNATELY THERE IS NO SINGLE SET OF JETTING DATA, AS ALL BIKE RUN DIFFERENTLY DEPENDING ON AIR FILTERS , ALTITUDE, PORTING ETC ETC.
