PK80 Wildcat Ported from California Motorbikes is Garbage

OK, which M/B engine & parts vendors have the best policies and quality

I can only speak for my own experiences on this, I always go to bicycle-engines.com as they deal exclusively with, ZTMoto, (Zeda Technology Co., LTD) as their sole manufacturer for the engines they offer...And lets not forget that they stand behind their products 100% with a soup to nuts 6 month warranty which they always honour with no hassle.

Good answer, your own personal experience = 1 review

Simply put everyone leans towards bicycle-engines.com over and over again due to their 6 month warranty. But they void under any modifications.

As do most everyone else that even carry a warranty...As a general rule, one should not mod out anything, at least until the motor is broken in so you know what you will be working with and if it even needs any mods once broken in completely, only then will you truly know if any mods would even be necessary.

As a point proven to Zane across this entire post his motors are failing due to the negligence of shielding the bearings to the magneto and smaller gear side for the clutch. Just as we spoken I have now had time to split the case open and show you what's wrong with the picture. Keep in mind Zane never offered to replace the bearings beside other parts that shipped out defective. He claimed on several basis one sided shields were not necessary. Every experienced builder I've spoken too has told me that they need to be shielded on one side. Nor have has anybody said otherwise to me. It's very obvious the magneto oil seal blowing was due to the compression and rod rubbing to hard on the seal. I'm assuming shimming and/ or sanding the rod would be the only true solution to resolving this?

Also the crank doesn't have shims whatsoever. Here's all the photos of PK 80 Wildcat Pro Racing bottom end split open. I advise Zane to contact me directly to send out replacements of bearings. Luckily I had a local friend who gave me some but this only for one case. I will have to do all three cases he sent out as they all have the same issue in the same areas.

I also would like to note, these bearings were crap. They ran very roughly despite of the engine oil and fuel lubricating them. Also the crank had no shim washers whatsoever for the crank.

Crank side no shield photo with oil seal taken out
