These are new aftermarket gaskets cut from Viton Rubber sheet.
 
Same profile as Yamaha OEM Prt# 4H7-14984-01-00, K&L 18-2619
 
These are far superior to OEM gaskets as they are reusable and Viton holds up to modern ethanol fuels.
 
All gaskets are made in the USA from material sourced in the USA. 
 
I guarantee these to fit and function as good or better then the original Hitachi gaskets!!

XJ650G/H/J/K Maxim 80-83
