NICHE 90cc Engine Piston Cylinder Gasket Top End Kit for Arctic Cat BRP Polaris Sportsman 90 A12101146000 0450007

Head received cracked

I use a lot of niche stuff great product but big bummer when ya order a kit and don’t get everything in the picture or description.

My daughters Polaris 90 was only putting out 71 psi so I need it needed a new top end. I was putting it off and putting it off even though I found this kit for about 50$ but I then received an alert that it was now 35$ so I thought well I can't pass on that. And I am glad I didn't ! I can not speak on the longevity of this kit or this brand because I just installed it and have not ridden it yet. But for 35$ it came with litteraly everything you need to do the top end it even came with a new jug ! seriously 35 $ and it comes with a new jug !!! And even more impressive is the fact it even came with new head studs and a new NGK spark plug! I seriously and honestly do not know how they sell this kit so inexpensively. No it's not a race kit but as it shows in the picture it definitely didn't he job ! From 71 psi to 125 psi that's a huge increase in pressure. Considering the manufacturer recommends at least 115 psi. (I was not compensated in any way for this review it was purchased with my own hard earned money)

Worked great for my 2001 sportsman 90.Installed and Started right up. Better than ever.

So far so good, only time will tell but i would say that there should be instructions for the beginner's,but easy to install

I've got 5 sportsman 90s and put namura pistons in 2 of them when they were $14. They ran good. Needed a cylinder for a different one and figured for the price i would try it. Runs as goofs or better than the others with Namura pistons. Cylinder looks cheaper and not the detail work around the ports but, i can't feel the difference in power. I'll buy another when it comes time.

Buyers beware. Small repair shop here. Bought this for a cheap customer. Cylinder exhaust port holes did not line up. I didn't catch it until it was installed. But I knew something was going to come up with Chinese parts. ALWAYS DOES! I had to use an air dremal to slot the exhaust header hole. You better know how to fabricate, not hack, if you buy this kit and you want it to fit professionally. But then again, why would you buy this kit if you were a professional. No guarantee here. The Chinese need to get their copy machines tuned. I also Used the OEM head cap gasket because the one that came with I could not imagine using it.

Perfect fitment for 2004 predator 90

Kit needs to have a needle bearing and a gasket for exhaust but otherwise exactly as advertised

Worked perfect
