NICHE Cylinder Head Piston Gasket Kit for Honda Rancher TRX350 12100-HN5-670 98069-57916 12100-HN5-670

Good

This was the first time that I did a top end rebuild. My bike was the victim of the big flood here in 2016 and I could not get to work on it until now 2019. Three years sitting with water in the cylinder destroyed the original. This kit came with everything that I needed to replace the original. Everything fit together perfectly and started right up and runs great. Make sure you adjust the valve clearance at TDC before starting. They were tight from the factory and I could not get the feeler gauge in without backing off. I have about 10 hours on it now with NO PROBLEMS. Great buy, glad I went with this kit.

Kit worked well in 01 rancher. Rings and piston were not China crap

Items were great

Wasted 10 hours on this, put it all together per OEM specs in manual, torque specs, valve lash, ring gap, ring orientation (I've done a ton of engine work, this isn't new to me.) Would not run, would only pull in 2 to 3 lbs of compression, tore it all down and double check ring orientation and sequence, still nothing, re checked valve clearance multiple times, still nothing. Checked cylinder for flatness, it was not even close to flat causing a leak at the base gasket. Closely inspected valves as they went through rotation and they would not open all the way. Fast forward a week later, I ordered a complete setup from Top Notch Parts and put it together in a half hour, running beautiful. Strong compression and sounds great. Not sure if I got an assembly from NICHE that was made on a Friday at 3 pm or what, hope this review saves some people time if it doesn't work out for them right out of the gate.

The jug gasket they send DOES NOT WORK you will need a green jug gasket for this kit to work.

Quick and easy top end rebuild bike now runs like new

This worked exactly as stated and fixed my 4 wheeler.
