Kitaco SE-Pro 124cc Version Up Kit for CRF50 CRF70 Monkey Gorilla and others. After years of domination with the Ultra SE head, Kitaco has now completely redeveloped it with larger valves, straighter ports, larger combustion chamber, new auto decompression camshafts, and even stronger valve train. Features include:
- 29mm intake valve, 24.5 exhaust
- reshaped intake and exhaust ports
- 2mm larger combustion chamber
- auto decompression, nitride coated camshaft
- stepped valve diameter to lighten reciprocating mass while maintaining strength and durability
- L shape, flex type piston rings
124cc Version Up Kits include new SE-Pro head, 54mm piston kit and top end gasket set for owners with existing 124cc SE kits or 124cc Kitaco factory engines.
