NICHE CYLINDER HEAD

  • A cylinder head is usually located on the top of the engine block
  • It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber
  • The passages in the cylinder head allow air and fuel to flow inside the cylinder while permitting the exhaust gases to flow out of it
  • The cylinder head uses a gasket that aids in preventing water or oil from leaking into the combustion chambers

The guide pin for the cam shaft sprocket was missing

This came ready to run out of the box. Machined to factory spec at a fraction of the factory price. Also it’s cheaper to just buy this instead of sending your head to a machine shop. This was put onto a 2004 TTR250

Head and all assy items appear top-quality, but the cam cover from my head is VERY different than for this head. The bearing is a quality SEALED ball-bearing, unlike the plain aluminum "bearing" that comes from Yamaha. Lots of nice upgrades to this assembly.I could order a new cam cover, of course, but I ended up getting my head machined to fix the knackered surface so I could keep all the same components.

The only thing liked so far is how fast it got here. Quality doesn’t look the best mating surfaces have scratches let alone being broken on arrival. Most would blame delivery service either way should’ve been packaged better.
