I bought a Wildcat kit from you. I have to say it's been pretty good, save for normal poor quality issues that plague all china doll engines. My choke went loose and took me a few days to figure, ran like crap till I figured out the vibration was closing the choke. I've gotten a lot of miles of reliable transpo out of it though, and I use about 1 gallon of gas a month. Yes, that's right, about 60-75 miles of riding a month on a single gallon! Would be great if you could figure out a regular warranty for your engines, but over at the motorized bike forum, most folks say you're good for resolving issues members have. I will definitely look to you first on future purchases. I do get spare parts on Amazon cuz I can save on shipping, but for engines and kits, CMB is a good source.
That was educational. I don't understand the reference to pressure when comparing magneto cover gaskets. I thought the gasket was to keep stuff out. Wouldn't that cavity necessarily be isolated from crankcase pressure? The first shot of the upside down cylinders shows quite a casting flaw in the Wildcat (left side of cylinder). Your concluding observation about not much of a price difference would be strengthened by giving the price of the Wildcat.
@@zsfabricating Yes, I had to replace the magneto rotating core one a basic "entry level" engine a year or two ago - maybe three. I think the coil part was OK.
Hit the screwdriver with a hammer while you turn it when removing the side plates. It's like a homemade impact wrench. It works too. I have a red amazon engine. Not sure what size it is though.
Great mr zane,, could you make a video how to assemble a wid cat, top end motor80cc, i bought one from ebay jan, 2021,,dont see the needle, bearing, nor piston pin & clip, nor cluch assy tool, parts missing, no instruccion, i saw your video, sad, for missing parts, & no instruction. Thanks, joe.
will the wild cat coil and mag. coil fit on the amazon eng.??? also what should the ohms reading be on the two coils??? please answer where i buy those wildcat engs.??? thank you please answer!!!
Wish I would have seen this video prior to purchasing not just one , but five kits from Amazon since September 2020, although I am actually content with the way they all run, they do have the smaller hardware, and it's more than bad quality, the kits I bought were "Anbull", any comments on these kits? Again, wish I'd come across your video prior to my purchases, the hardware alone is awesome on them thar Wildcats. Thanks for making this video. M.
Nice job, I'm sold. When in 2020 do the new cylinders become available? I will be ordering a motor but am waiting for the newer style cylinder to be included. Thanks!
Really cause La hover sprayed water all over it and it had no issues I only drilled holes in the front portion of the cover to help keep it cooler , I was more so asking about it taking away some compression from the engine
I agree with most points made..... but right off the bat "pot metal srew's" ???? LOL! - I have built a few bikes (27), some for sale but most for members of my family and friends. The first bike I built was with a cheaper eBay purchased motor.... much like the one shown here. I have tried motors from several companies, I do have three bikes that I have built with the runwell PK 80 motors but have changed out the heads on all three to performance heads - all in all I think runwell makes a pretty nice motor and for now it is my "go to" motor - it is in my opinion one of, if not the best on the market right now. There are other motors..... But for me?... I'll take a runwell PK 80.
@@st.paulmn9159 - yeah, it's the balance of the Runwell that makes it the best for the price. Ports are pretty crappy on almost every motor before a port job. I have one that I ported and I got 43.8mph on 26in wheels and 40T sprocket. (it might have gone faster but the bike was making me nervous 😬) - I have 2 more that I'm playing around with and swapping cylinders on, one to a G4 open transfer port cylinder and the other with an iron sleeve that was a G4 before it was sleeved. I cut the splitter out of the ports on the sleeved one, couldn't see the point after the sleeve job I think they just kinda became an obstruction. - anyway.... I'm just rambling because I'm excited to get them together and see the difference.
That doesn't address the many quality issues also associated with the bottom end of the low quality engines. However, you may be able to, however sometimes you may have to use an extra gasket when interchanging cylinders across factories or in some cases the piston will hit the head.
This is actually not true, you dont want you clutch to bite, you want it to slip a little, so your engine will not fall out of the power band, actually you can start with Chinese clutches without pedaling, sthe spring is very tuf it will not slip.
i bought 4 coils on ebay no good they will do nothing about it so far!!!! where do i get ign .coils for 80cc that are good???? no call numbers no computer replies you just get off !!!
Bought one of those eBay motors for my first bike. Huge mistake. Nothing but trouble. It’s currently off the bike the bike is completely shut down for now and I’m building a completely new bike with an actual engine, not just a bunch of scrap parts thrown together and called an engine. The eBay engine literally has spent most of its very short life being worked on vs actual running. Not even exaggerating. Never ever even consider buying one those cheap eBay or amazon kits you are throwing your money away, they are horrible and will leave you with an undeserved bad opinion of motorized bikes. You get what you pay for and these higher quality kits are not much more at all.
Robby Clark i completely agree I got my first motor off amazon it was sangemotorparts and the motor never had a clutch spring it which I didn’t care cus it worked for the time I got it in April and yesterday the clutch shaft broke and I would have to mess with the clutch almost everyday and it was such a pain in the ass I said fuck it and bought a motor off gasbike.net today h
Brainless Gaming Yeah I went ahead and ordered an engine kit from bicycle -engines, the Zeda 100. Ordered on the 29th of August, still waiting on it??? They shipped me the wrong engine the first time and I finally got it sorted out but I still haven’t received my engine kit. Not trying to knock them or anything but at this point I’m definitely going to do business with someone else next time. Probably either these guys at California motor bikes or more likely bicycle motor Works. I have emailed the guy who runs BMW and he always emails me right back, even to just answer dumb questions so he seems really legit and definitely knows his stuff. Good luck to you.
Robby Clark My engine works fine I just bought mine around a month ago and have over 500 miles. I had to buy a NGK spark plug and a new muffler because it broke.

Wildcat with Cali motorbikes is the way to go got few of em and will continue to buy ur kits ty
A lot of difference, not much more money. Great video!
And I was just abt to drop 160 on a ebay one thanks for the video man !

The magneto is very water sensitive. If even a single drop of water makes it in there you have the replace the magneto as the engine won’t start
@@zsfabricating Yes, I had to replace the magneto rotating core one a basic "entry level" engine a year or two ago - maybe three. I think the coil part was OK.
Thank you so much for maki this video!!! Is very helpful. I will never buy 80cc engine kit again on eBay. I already got cheated
great info, just wish parts were kept on same side the whole video. you kept moving them from left to right. I could follow but for others..,,

Great video brother very informative
That Wildcat motor looks a lot like the Zeda 80cc Firestorm Edition.

Thanks for the great informative video wildcat for me very soon
I gotta one piece cylinder motor off Amazon 😮 this is just great.. however my seller is out of California
Same who do you buy from
Motoos?
a thicker screwdriver with a rounded tip should get the screws out of the amazon/ebay engine
5$ hammer screw driver with good philips works well on soft screws use it first!!!!
Thanks speed man video is very helpful
Nice!
I just bought one of your 66cc kits, currently in the mail. Are they now shopping with the new cylinder head? Thx.
yeah
Works great. I commute with it 12 miles round trip 3x/week at the moment.
Cleverest good luck
are the new wildcat cylinders out yet? and great explanation man
Tmas Official yes. And thank you!
i bought one from these guys last august. been out for a while. i felt about a 15% power increase. very nice.

Jim Jensen those cylinders are not new, theyve been out for 2 years now just search g4 cylinder on ebay
can you add link to the place that sells the Wildcat? if the wildcat isn't much more i'd like to get one
Where are the wildcat motors manufactured?
Does it really matter about the gasket for the magneto cover ? Cause I drilled holes in mine 🤣
I would get your gasket replaced before it rains again. Water will make the magneto die
Really cause La hover sprayed water all over it and it had no issues I only drilled holes in the front portion of the cover to help keep it cooler , I was more so asking about it taking away some compression from the engine
Can you tell me the gas oil mix ratio for the wildcat ?
32:1
What kit would be best for a mountain bike with a 1-3/4" inch diameter down tube ? Thanks
Can you climb a hill with it?
Does the desing of 80 cc engine without head are goods?
So I'll be using the wildcat bottom end with the falcon 911 Dio Reed cylinder should be a good engine.
Thanks Zane

Ok there chatty cathy
how much is the Wildcat motor ?i may get one
Thanks for this video because it really helped me...I didn't quite understand the differences between the to but i knew the eBay motor was shit
Thank you! Where did you get all of your knowledge?

@@ReMarkAbleMagic well 3 years has gone by and I probably know more
The new cylinders are not available now?
I’m pretty’s sure u can’t stamp a piston my guy
Can the low quality black one whole cylinder be replaced with a higher quality cylinder and head?

just put the white lights wire to a switch so it is not engaged when turning the engine on...
Has any one had a chance to check out the wildcat avenger 85?
do this engines have oil in them or do the get it from the mixed gas?
Both engines are two stroke and require a 32:1 oil gas mix.
@@zsfabricating but is 16:1 good when its brand new
@@aski1529 no
The rod on the black one looks wider then the wildcat
Dominic Thomas it’s a different rod. The Wildcat rod is stronger and a little longer, (40mm stroke instead of 38mm)
@@zsfabricating Wildcat use low hole pistons so it's a short rod
Better Fasteners good
anyone know where to get a good kit in europe? specifically Lithuania.. I don't want to pay half the price of the motor for shipping alone...
