These are new aftermarket gaskets cut from FKM Rubber sheet.
 
Set of four gaskets
 
Same profile as Yamaha OEM Prt# 2A2-14984-01-00, K&L 18-2617
 
These are far superior to OEM gaskets as they are reusable and FKM 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 Mikuni gaskets!!
 
Fits the following motorcycles:
 
XS400D/E/2E/F/2F 77-79
XS500E 1978
XS750SE/SF Special 78-79
XS1100E/F 78-79
