I ordered a new Boom Rugged 150cc scooter and it was delivered today, with some assembly required. Now please keep in mind I am new to the scooter world and definitely not a mechanic or very mechanically inclined. I am aware it is a Chinese scooter with a gy6 engine. I got it assembled with minor issues, referring to the front wheel, handle bars, shocks, mirrors, etc. I noticed when I was unpackaging all the wrap and guards that the cvt transmission has a hose coming out of the top of it but it is not connected to anything. Should it be connected to something? Are there any other hoses or things I need to check to make sure they are connected properly before I try to start it up? If you have to dummy it down for me I won't be offended. Any knowledge or help would be great and much appreciated!

That Hose is a Vent for the Gear Box in the rear of the CVT.
It goes to or attaches to nothing she just vents.
You may want to look under the hood at the Vacuum Hoses to and around the carb to make sure they have no visible issues.
Trying not to scare ya on the but the GY is notorious to come from the Factory with a tight valve lash. I adjust mine right out of the crate and it was tight (was under .002). the issue is if they start out to tight once the GY is broke in they don't get loose they get tighter and eventually once the motor is hot the exhaust valve will hang open slightly and the engine will die until she cools down and repeat.
There are plenty of GY tutorials on this so there lots of help if ya need it
Your all good

Thank you! I will open her up and check out those hoses and look around the area for anything else. I'll try and find a how to video so I can get that adjusted today. Later I plan on buying a better battery and plug but for now I want to get her finished setting up and ready and take her for a trial run. Then I can change the oil and tranny fluids to something better.

Ok
I would for sure change to Crate Shipping oil in the engine to a quality Dino oil for break in.

Yeah I changed both the oils today but didn't get to adjusting the valves yet. The break in period is kind of a buzz kill with just poking around town taking it easy.

Don't be Babying it around town.
The Most important thing is to vary engine Load, example. going up hill on the gas is a nice Load, Coasting Down hill is No Load.
That means do not be afraid to lay into that throttle for short periods of time. Pin it up hill for a couple seconds then back off to 50% then to 75% then to 40% then to 100% with a load on the engine.
There isn't a a bunch of jagged edges and those sort of things in these engines and the finish on the cylinders is the modern Plateau hone, these will seat the rings in a very short period of time. if you Baby it it will grow up to be a Baby..
Have Fun

Lol. Ok thank you for the advice! I will give that a try. I haven't figured out yet how I'm gonna get it apart to adjust the valves yet. The videos I seen was with the engine out on a table, not in the scooter. As soon as I get the extra cash I'm gonna follow recommendations to put better hoses on, a magnetic oil plug, fuel filter, spark plug. One thing I can't find is info on the valves stems. I seen to replace those too but I have no idea what size they are so I can get some better ones ordered.

Don't worry about adjusting the valves yet put a few hundred miles on it first.

Great! That means most likely bought from a dealer who didn't check and you didn't check it so you Don't know.. |

So I haven't had time to check the valves yet or adjust them but yesterday when I went for a little ride I was pretty pissed 5 mins into it. List of problems that happened all in that 5 mins:
1. Fuel gauge is bouncing all around up and down and Idk why.
2. Screw came out of the handle/mirror attachment area and my local hardware store didn't have one that fits so I will have to go out of town or online to find one to put it back together.
3. Had to put the throttle cable back together cuz it came loose from the carb.
4. My muffler is rubbing against my back right shock and idk how to adjust it to get it to stop.
5. The hose that goes into my air assembly, where they glued it or whatever, well that is separating so I may order a new one if I can find it or try some opoxy to seal it up.
So yeah I am irate at the moment.
