The Ruck Shop rules!! Great video! I installed the same NCY 171cc Big Bore Kit that I purchased from the Ruck Shop for a great price!  This video was an excellent step by step guide for me to install my kit and it answered all of my questions.  Much Thanks and appreciation to Ryan and Kevin for their professionalism.

Hey thanks guys I just got my 171 big bore kit in your video really helped me out? One thing I know that’s not n your video that you didn’t do that is I recommend is dropping a little bit of oil in the bottom of the cylinder body and then the top of the cylinder body and work the piston back-and-forth

Thank You for your Tutelage. Ilearned more on this one video than on all the videos I've watched, combined!! I have an 80cc engine that had the Spark plug tread got stripped on the bore, and I would lose compression, and the engine would stall and shut off at stops. I don't know why or how it happened. I need to remove and replace the Bore and was not sure if I could do it. Now I can safely say, that I can positively do it and be on the road in no time. Again, Thank You for the Video Keep them coming!!!!

When doing this, please don't forget to put assembly lube on wrist pin, cams, lube cylinder before putting a dry piston in and running it up and down dry several times. On first crank up, its going to turn about 300-400 times before oil gets to piston and cam. Easier to install g-clip in on one side before pushing the wrist pin in too. As always, all your videos are very informative and educational. Thank you for telling everyone about the bolt size reference on torque specs. Also, I am assuming the since this is a complete kit, that the ring gaps have already been checked at factory?? Keep up the good work, will be ordering mine after Thanksgiving.

Great video, thanks guy's, The Ruck Shop is awesome!

Having a hell of a time getting the wrist pin installed. It seems like I need to press it in there with a tool. I’ve seen a lot of videos claiming you can just push it in with your finger. Maybe on a brand new engine.

Thank you. I have purchased a super red 200cc from red fox and could not find any supporting documents for 1p61qmk engine. This helps a lot.

This video is absolutely amazing, all questions answered with visual proof. I don't have a Ruckus but looking forward to doing business with you guys for my 150cc Tao Tao engine upgrade. I was wondering if the process will be as easy (no boring) installing a 180cc?

Very interesting and thank you for such a professional demonstration. I have a 2016 SYM HD 200 Evo (171cc motor) now with 10k miles. My bike runs silky smooth and it still looks brand new as the day I rode it away off the dealer lot. So yes, I do change the oil at up to 600 mile intervals max. Maybe that's a bit over-the-top frequency but w/o an oil filter on the GY6 the oil does get very dark at about 600 miles or so. I do all the other fluid changes myself too. I let the pro scooter guy at my local shop (Seattle Scooter / Cycle Center, Pete) do the serious adjustments and stuff. I am not a gifted scooter tech.

Question: Why are there two oil drain plugs on my GY6 171cc? One on each side down below? Also, should I continue to do a full oil drain removing both plugs for every oil change? Am I starving the engine when remove both plugs? Should I just do one side at a time? I'll stop rambling now.

Thanks again for your professionalism.

[kevinstearns]

[darynbundy]

Do you have any videos on taotao gy6 150cc engine rebuild and complete wiring harness install? .. also if like to thank you for doing these and taking time to explain things. Most of the others go thru everything in fast forward which unless you have superman super speed, you'll never keep up

[mandapalque]

This are great people. I have been in their store and they are amazing.

[lpacheco]

thank you for this video. I will turn my50 to 100 at some point. this helps a lot.

[DankUrbanBoss]

Amazing I appreciate you guys doing this video!

[AllLifethingschannelyt]

Tried this on a 50cc Scott millington Motorsports jiajue rocket scooter with 80cc big bore went threw two. Every 500 miles

[kranosriger]

guys is it safe cause the metal left on sides are pretty thin, will it work good for daily use

[AllLifethingschannelyt]

A Honda rukus is liquid cooled as well probably would of handled a 80cc big bore on there 50cc better than mine

[jemarmiranda]

here in the philippines some branded motorcycle owners discriminates us because we are using gy6 motorcycles, they always say that its cheap and its not durable....and some people bullies me on my youtube channel :D
