Ive never once seen one of these engines in any trim be something i was impressed by. They all seem like they were engineered and manufactured in pakistan on a dirt floor.
@@DirectCurrent4udue to it using a minarelli upper it's an actual true 70cc. The Chinese would rate it at around 85 or so. I can't be bothered doing the port volume math that they run to beef their numbers.
Grubee GT5 engines used to be the best standard chinadolls, mostly due to Don Grube spending a lot of time in China overseeing production. His biggest problem was keeping the chinese factory from substituting lesser quality parts to increase profits. Nowadays, Olyin seems to be one of the best around....but china is gonna china, so I ALWAYS go through any new engine before use.
Exactly. The eBay/amazon engine sellers don’t have strong brand loyalty, therefore their goal is to get the price absolutely as low as possible, as they aren’t worried about return customers and want to maximize profit. The wildcat engine is made in a different factory with a higher quality capacity and is also set to a higher standard. The truth is, with Chinese manufacturing really low or really high-quality can be achieved, it depends on the price required for the market. For some people, saving $30 may be something they’re willing to do, but in the long run you don’t save money and you have to deal with a low quality engine having constant issues, unreliability, and lower performance. These engines now having the smaller flywheels to save money is basically a nail in the coffin, as people might be willing to tough out low quality but when it comes to even having to deal with a slower engine, people don’t want to deal with that. It’s just not worth the savings.
@@masterhacker1989 first of all it’s an indicator of quality. Secondly, the crank case gasket will blow out in that weak spot within a few weeks and all your crank case pressure is gone and so is your performance. Also, when you want to work on the engine, the gaskets will rip when you try to takeoff your covers.
@@neoboost6377 the fraction of the ounce of weight difference I believe is attributed to the pins on the piston, which are not well seated on the lower quality piston. This means that the low quality piston is more likely for the pins to fail and cause the top end of the engine to have a catastrophic failure.
Put a 5lb weight on the scale then zero (the tare button) it, then put the engine on the scale, take the number from the scale plus the weight you added to get the weight of your engine
@@TheShivABC thank you! I recently bought a scale good up past 50 pounds and was able to determine that the engines weigh about a pound different, around half of this weight difference is from the heavier bottom end with the slightly larger flywheel and denser internals and the larger surface area on the cylinder/cylinder head made up the rest of the difference in weight. Thanks for your comment.
This video is a perfect insight and description of the CCP's/PRC's manufacturing 'quality products' for Amazon's & Ebay's recommended/sellers sales advertisements. Spread the word, don't be fooled by CCP technical & mechanical 'quality' products, whenever possible, avoid.
Yes, better to buy through American company like California motorbikes that can set standards and do thorough quality control before anything gets sent out.
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)
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
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.
So one reason to go with the grizzly mini is because of the roaster and the water heater they have for it and the Capybra doesn’t have that for it and also the tools to clean out the stove
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.
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
