This is a BRAND NEW pair (that's a set of 2) aftermarket Yamaha Banshee COOL HEAD DOMES
These are STROKER domes, meaning they will only work for a stroker crank
These are cut +2mm deeper, meaning they are drop in ready for one of 3 piston/crankshaft setups:
1. Wiseco 795 pistons + 4mm stroker 115 long rod crank (no spacer plate)
2. Wiseco 513 pistons + 4mm stroker 110 short rod crank (no spacer plate)
3. Vito's SUPER STOCK pistons + 4mm stroker 110 short rod crank (no spacer plate)
All of these have a 13 degree squish to match the pistons
These domes are brand new, available in any size (see our other listings for other sizes)
These fit oem factory Banshee cylinders with a standard bore 64.00mm to 65.50mm (will not work on big bore re-sleeved cylinders)
Come with upper o-rings already installed
Will work on most aftermarket heads, Pro Design, NOSS, Chariot, VITO's Hemi Head, ModQuad, ADA, etc BUT NOT TRINITY
