Thank you, for putting these videos about assembelling the motors i realy learn a lot and just sucsesfully changed the cylinder head from my gy6 150cc .

This video was awesome and very very helpful. I’m new to this hobby and I definitely enjoyed watching/learning how to put this engine together. 👍🏻👍🏻

Awesome video!

Hi its Jimmy just watch your new build and could not have had a better exsplaned in detail nice and slow pace easy to understand what you are doing . This session of your build would be nice to send to all small engine repair college to show and tell class.

Great video brother I really enjoyed it buddy

Watched this again after purchasing a1p57qm project bike (boom brand, like a rugged) and I can't wait to get into the build. This video is awesome in an auto tech built lots of performance car engine no bike motors though but I can see it's the same just way smaller scale. More i just gotta test mine apart. Doggie or what HAS to be done and then plan the build. I can't afford this compete set up but I'll probably do some of your upgrades. And buy my needed stock replacement stuff from you if I can.

Bro I’m ordering from you every time!! Very informative!!! Ordering the big bore next time I put on road !! The 200 plus kit fit on a Ruckus??

I love you guys! Best info, best parts! Do you have (or recommend a source) a bolt and stud kit for gy6? I am installing a 47mm cylinder and head combo with 69mm valves in my pony 50, I'd prefer to upgrade the hardware too from the chineese bolts and studs.P.S. I'm not afraid to tap for larger diameter studs!

Sweet

Hey man, great Ruckus idea for you. Build a hybrid ruckus. A hub motor up front with regen capabilities. Change the twist throttle to two thumb throttles that can be pressed simultaneously or individually. One thumb throttle for the engine and one for the. Motor. Another thumb throttle on the left grip to activate regen. battery pack and bms under the seat. The hub motor will really give you the torque and power to merge and move around in traffic when it’s is needed. Can add to top speed when needed, and will increase the fuel mileage also. I’ve been wanting to realize these ideas for awhile but you have the resources to make it happen. It’s the best of both worlds. Would definitely be helpful on a GY6, but would really shine on the stock ruckus crowd.

Why will a cast piston last longer ?

@helloish12321

Жыл бұрын

Forged pistons expand more when they get hot. They have to design them so that at cold start temperatures the piston is excessively small. It will slap around more until operating temp is reached. Cast doesn't expand so much when hot so the cold clearances can be designed tighter. Forged is generally only recommended for high rpm or turbo stuff. Here I would think it's mostly unnecessary.

For longevity that doesn’t pop up as being an issue. These can last just as long or longer then a stock engine top end. Keep in mind your stock piston, cylinder and head are very low grade made in china. Our kits are top of the line materials made in Taiwan. Keep up on the maintenance and they will last a very long time. How long exactly???? That’s depends on how you treat it. But like I said that isn’t a issue that comes up.
