Fake 100cc Motorized Bike Kits- Huge Problem

[@jwserge]

*Is this **10:35** "Wildcat Minarelli 6 hp" really doing 6 hp?* And is it really reliable? Are there real positive feedbacks?

[@catsbyondrepair]

of course the minarelli is gonna have more torque it was designed to push a 500 pound scooter. the aluminum athena cylinder is better no cold seize issues

[@pamew]

Aye, seen a couple of well intentioned but naive people slap those minarelli kits on mag wheel and skinny spoke wheels. Then they wonder why they get constant warping and breaking issues. Like you said, That immediate torque you get Vs the crappy Chinese factory cylinder/head combo is wild.

[@mikecyanide7492]

Not a good look to lie about the phanrom and upsell your own crap . Note- the person in this videos name is Zane. He OWNS California Motorbikes! Yet say "they" offer instead of I. You do the math here.

[@Littleevil9975]

Good video bro and you’re right a lot of these are just a stock kit with an upgrade they’re not performance and that head that they’re selling with. It is junk I agree.

[@oimpastato]

Great video, and thanks for the feedback! I actually purchased the Wildcat Plus Upgraded Ported PK80. Cylinder is ported as described, and the magnet is very strong. Did notice it was hitting the coil, but a quick readjustment fixed it. Muffler is not port matched. CM shipped mine in two separate boxes to keep the rate low, so I am still waiting for the 2nd one to arrive. Very eager here.

[@marcusprince3999]

Did you end up receiving the 2nd box?

[@razor1uk610]

@oimpastato How goes the newer motor compared to the tofu dreg one you used to have ? If all the parts eventually arrived, it should be run in by now yes ?

[@dmoore0079]

I started out with the BT80. It's a shame the cylinder design has such insufficient cooling, because it really is a great quality motor overall. The high cylinder temp combined with the very short intake almost guaranteed it would vapor lock and stall on a hot day. I managed to reduce the heat a little by retarding timing, and running a thicker oil mix (25:1). Replacement cylinders were almost always out of stock, so I just gave up on it and replaced it with a generic 66/80cc that I ported and converted to case reed. It's more powerful than the BT80 and much more reliable, but I miss having the stator to keep my battery charged for my lights and accessories (just manually charge every couple of rides).

[@jeffwalters6044]

Thiers a few yd100 that r damn good

[@philsparrowk-b3d]

Not crazy about the fixed head. Makes it hard to adjust your squish. Really hard and the Chinese motors aren't adjusted to 1mm - .

[@adamsmy8121]

Im looking at the ebay engines im debating on an 80cc vs a 100cc the 80cc has an nt carburator and the 100cc has the carburator with the red rectangular cover im curious if there is any difference in those carburators and im also curious if i will see any amount of performance increase with the extra 20cc and if so how much 20cc difference? Any info if you have it would be greatly appreciated

[@kingti85]

What did you end up going with? I just bought a 66/80 from eBay for $90 and it seems good so far. Mine came with the Bofeng carb

[@philsparrowk-b3d]

Ccs don't always matter. There's something to be said for displacement but it's not everything. 80cc and 100cc china doll motors aren't really that. So they say. There more like 66cc 79cc. When you look at it the 85cc motors are their go to for performance motors.

[@rcadventures4342]

Nice video, what mike did you use the audio sounds really good…

[@dustinh4175]

I heard a phantom 85 top end will fit on a cheap $80 USD 49mm iron sleeve bottom end. So about $180 for a ghetto phantom without the exhaust pipe.

[@JMB676]

It fits on a yd100 bottom end with a 50mm piston but all you need is the yd100 bottom end.

[@johnd.5601]

I have a Zeda 100. The 1st cylinder and piston broke. The piston pin retainer c clip snapped and got stuck between the piston and cylinder wall. I have replaced the cylinder and bought a windowed piston with a different type of c clip. I also put a reed valve and upgraded carb. It's been running really good. I live in a area with lots of hills.

[@gododgers16]

I got a Zeda 100 also. When they come stock the piston is installed the wrong way. Not sure if you flipped it or not.

[@brucesnyder7368]

I ran a yd 100 at 39 mph (GPS) with nt carburetor/ jet size .71?) and stock exhaust , with a 41T rear sprocket. The unbalanced bottom end vibrated excessively for enjoyable riding, to say the least.

[@danajett]

I'm interested in the wild pk80 with a race head I saw on ebay is it worth the buc ?

[@tolanstout]

Can you do anything to fix the inherent issues with the 100cc motors? Is the bottom end compatible with a 66/80cc or even a Minneralli top end?

[@mikecyanide7492]

@@tolanstout theres nothing wrong with "100cc" motors. If you don't like yd100s just get an ld100 cyl and cnc head. Never overheat built right can pull a 32t 50mph+

[@philsparrowk-b3d]

IDK maybe all that but as far as your question goes the bolt holes can different. Some pk 80 bottom ends have 6 mm bolts and the minarelle upgrades "usually" are 8 mm. If you get California motors they are 8 mm. because there for a wildcat. You can get this upgrade other places.

[@DogsaladSalad]

Dang it I just got a Zeda 80 and I didn't even know Cali motorbikes even exsisted

[@philsparrowk-b3d]

It's not a bad motor to start with. California motors are definitely an upgrade and no I Don't work for them.

[@brianrasley7203]

Whats up bud .first off thank you for making the first video ive found that provides solid info . Keep em comin second im lookin for a complete kit that i can use daily. Sadly my budget is not the best 150 or less. Im 220 lbs so i need something with some power if you have the time, could you please give me your opinion on what kit I should get. Thanks in advance

[@philsparrowk-b3d]

I'm sold on the 80cc minarelle non ported motor. 2 reasons. One you didn't mention is that it has the wildcat Lower end. Which is heavier and stronger and has a balanced crank.. 2 it's top end is minarelle style cylinder body . it's cast iron for better wear , it can be bored and honed for a Large piston and has. Better heat displacement because it's cast iron. The only thing I don't care for "and I'm sure it's not a problem" is the small head. The porting on these I like to do myself. No offense to California motors but there.are opening on the transfers that can be done for better performance. Excellent video . This keeps consumers informed. The only kit I've seen come close to some of these are Smoliks 85cc menace motor kit.

[@pistonkeeper]

I've been building these kits for about 20 years. I started when these were coming from China with a lot of the Russian part in the beginning. The only kid that was ever truthful was the 50cc or 48cc in truth. The 66/80 I never understood, and they always put cc after like it was an 80cc engine. I've looked at all the 100cc kits there still 66cc. They've gotten away with it for over 20 years.

[@SyberSqueegy]

In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However, in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all "100cc" engine kits on the market today are actually 78.6cc in displacement size if measuring by US standards.

[@jwserge]

@@SyberSqueegy В России, мы никогда не добавляли объём камеры сгорания к объёму цилиндра. Я про такое, слышу впервые от тебя.

[@DirectCurrent4u]

@@jwserge You are correct. This is a china way of measurement.

[@bigjay6743]

Yeah I bought a 100 CC engine and my 80 CC engine has way more get-up-and-go.

[@theogagne519]

if its the yd 100 its normal they are really bad but if youd try my bt100 you would love it

[@randyrhodes9124]

a 50cc will top out at 35mph with 36t sprocket so paying 200 dollars more for an extra 5mph with a bigger motor aint worth it to me

[@trentbikes]

just port it, upgrade carb and pipe etc and you'll get extra 15-20mph or more

[@randyrhodes9124]

not gonna risk fucking up the cylinder tryna port it and i doubt a carb does anything to improve speed the only upgrades that make any difference is removing the exaust cap and air box maybe a smaller sprocket

[@randyrhodes9124]

i put a 40t sprocket on it and got it to 34mph so i was thinking maybe a 36t would get me to 37 38mph?

[@trentbikes]

@@randyrhodes9124 it should get you up to about 40mph. 32t might give you a bit more speed however it's definitely overgearing, you lose some torque, but it worked fine for me on my minarelli 26in wheels. 40mph 9krpm on 40t, 45 on 36, 50+ on 32, for me. could easily still climb up hills at about 40mph+

[@jwserge]

6hp can do 45 mph. Is it not worthy of that?

[@philsparrowk-b3d]

I just wish the exhaust for the minarelle was by cheaper. It's a bit pricey.

[@I.M.SofaKingdom]

You didn't ask, but I'll give you my opinion, if you want it. I've had both, and I think the yd 100 is worth the money. It is faster, higher end parts, better carb. I have heard the bt 100 is the best of the 100's, but I haven't found one. I think you have to order it from another country, and s&h runs about $200.00l)

@@intromortti Again how do they know or determine what size engine is on your bicycle? The china-girls all say nothing about size, so unless they are going to tear the engine down, and get calipers and measure the bore and stroke, there is no possible way for them to tell a 49cc from a 79cc, as the heads and cylinders are essentially the same. It is the increased internal displacement that differs. So how they gonna fine you? Sounds to me like someone is being punished for another's foolhardy actions that basically ruined it for everybody. It happens here as well. Idiots like I have mentioned have made it to where some states require a VIN be stamped on a bicycle and is treated like a motorcycle, some just impound and never return them. Again where I'm from we ride and are legal to operate on roadways and have to follow all bicycle rules, use lights at night, wear a helmet, and drive like a sane person with respect to other motorists and pedestrians, and all they ever do to us...is wave hello!
