THIS KIT COMES WITH A 1 MM BASE GASKET SPACER, AND 2 BASE GASKETS

IF YOU USE THE STOCK TRX90 HEAD YOU WILL NEED THE SPACER,, BUT

IF YOU USE A HEAD WITH A BIGGER DOME, YOU PROBABLY WILL NOT NEED THEM.

THIS KIT INCLUDES EVERYTHING SHOWN IN THE ABOVE PICTURE

WITH THE 54MM 114CC CYLINDER KIT THE TRX90 CASES WILL NEED SOME ALUMINUM REMOVED (SEE KIT INSTRUCTIONS BELOW FOR DETAILS AS TO WHERE IT SHOULD BE REMOVED)

I USED A DREMMEL TO DO MINE AND IT WORK JUST FINE
