This proves to show these engines are constructed with the cheapest labour and parts made. If you spend time scrolling through amazon and aliexpress you will begin to understand all the parts that have issues or are failing their some of the cheapest made and worse reviewed. My intake(s) were beyond terrible. When I mean terrible. there was so much goop of weld hanging in the inside of the tubes on both sides. I litterally had to port these just to match the carb intakes. Otherwise i would've dealt with metal shaving projecting into my motor or proper air fuel displacement. The PZ16 chinese knock off carb is also terrible. Out of 1-2 motors one was defective. I reached out to Zane yesterday and he is honoring to replace a bunch of defective parts I described previously out of the box.
I highly doubt this will fix the issues I;m currently having however. First piston blew up initially because the windows on the piston are too large and the material is very thin. Therefore meaning any lack of proper air-fuel mixture is catasrophic especially in lean settings and high rpms. Just like people had issues with the previous versions of the Phantom 85s. Well it's the same exact issues. If you inspect the new Phantom 85 v3's you'll notice they campered the edged of the bottom of the cylinder because the piston rings were snagging during heat expansions.
I did have a moment to remove the cylinder head and inspect whats going on inside. I replaced the seal with a Viton and even tried a spare from a salvaged 66cc crank case. Neither fixed the issue(s) after the motor initially blew the oil seals on the magneto side. Both motors failed to operate properly thereafter the seals blowing. So with extreme caution and advice I've come to conclude the pistons, crank, and other components start to give out at the same time frame.
I treated my second Wildcat like an infant child. Break-in very carefully, heat cycled, average speed 15-20mph, I only brought it up to 30 mph a few times on main bike strips and roads, It's proven to show these motors are NOT meant for daily commuting and will slowely will tend to fail if ran longer than 30-45 minutes.
Another issue is many people even suggest in these classic aspects that you shouldn't modify motors with Reed Valves until after the break-in.
After the disaster of two motors after 500km suggested on his website. Neither held up. I'm really regretting this because at the time of eying his ported engine the only thing that sold me was "ported". I even paid extra to have it with the cnc head, he forgot to send it and then sent one out. I could've avoided a headache and purchased this instead and dealt with their 6mo warranty. It's not personally my hobby to give anybody a bad review, but when it comes to hard work, money and labor it's an entire different story.

Zane has requested I contact him directly if I have any issues with his product and not post on the forums. My purpose is to fairly review just like across the board the entire motorized bike community on forums and YouTube.
I haven't pulled the cylinder head off yet and will be checking it today. I have a feeling due to the preformance of the motor on a early basis of having a CDH88 exhuast and the reed valve. It's too much rpm for the motor and it didn't seat the piston rings properly during the warm up and heat expanison of the piston rings. It's common sense at this point. Perhaps campering the edges of the bottom cylinder wall at a 45 degree angle will prevent piston ring sang. However this is just assumption partially. I will take the head off today and photo it and see what your opinions are. Keep in mind I never high reved this second motor on ANY warm-up. However after about 300 miles is when it's point of failure started coming. During cold starts I litterally had to blimp the throttle every time to get the carb and reed valves to properly operate. I'll keep you posted with photos and try to reach out to him again to see if he will be honor replacing the cylinder and piston this time after photo documenting and discussing with him. He is quick to replace parts as necessary.
He is sending me a Catnip CDI, pz16 carb, x1 stock cylinder head, 2 sets of oil seals, and a new piston for the Minarelli which the piston punches were too far in. I'm afraid none of these are going to fix the current issue I'm having start the Wildcat but these were defective on arrival. So keep that in mind.
I have more work, labour, expense and time invested into these motors than what I feel their personally worth. If you want something you can race down a strip on a very occasional basis and drive like an old man. By all means this is the motor for you. But be advised these motors require A LOT OF matience and things WILL fail when the oil seal on the magneto side BLOWS during break-in. Both motors didn't exceed past 550km a
My piston was cracked I have went through 2 pistons and 4 sets of piston rings and dude won't help my situation out at all I can't even get him to return emails most of this time I have had my ported Wildcat since end of October still won't start and all he's done is sent me 1 replacement piston. The intakes were absolute trash dont know how that passed his hand inspection before sending out orders. I still waiting for a reply for an email from 1.5 weeks ago. I sent him an email telling him ive gone through 2 pistons and the rings and still can get it to start and all he said was what's ur fuel/oil mixture.
