So my 2016 ice bear maddog is starting to make me mad. First ive bought the stupid thing on 18th of July 2016 but had to order it. The scooter didn't end up making it in till Saturday the 23rd. I didn't pick it up until Monday the 25th of July, so as of right now ive had it for 1 week. Ive already had to take it back to the shop where it stayed Wednesday and I picked up late Thursday due to the rear brake rubbing the hub as I would drive. Here is the new issue: After driving for about 5-10 minutes, my scooter will randomly start sputtering and eventually die. I would be driving fine and then outta nowhere as I'm goin down the road it starts sputtering and slows way down. Sometimes it will slow down then catch the throttle and speed up again. Other times it just dies. The damn thing only has 103 miles on it. Just yesterday I was stranded for an hour at a gas station because it wouldn't start. I was going aroun 50mph ( I weigh 160) and then it did the sputtering thing so I pulled over and it died. I then tried to immediately start it back up but it would. It would click like it was trying to but no luck. I then waited for a while thinking I had flooded the engine and tried again. Nothing. I then pushed the scooter a quarter of a mile thinking maybe I was to low on gas. It read 3 bars above empty but hey what the heck. So I fill it up with  octane fuel. Still wont start. I then went bought a Gatorade and candy bar. Ate and drank them. Waited over 20 minutes at this point and tried one final time before having family come pick me up. On the very final try it finally kicked over and started. Does anybody know what the the issue could be? Ive literally only put 103 miles on this. I drove it for about 30 minutes before it started acting this way but other times it will start sooner. Thanks in advance. |

Your troubleshooting strategy does not appear very effective! How about testing for spark and fuel flow. Floor level gas tank with a vacuum-pulse-pump is always suspect . . consider electric. |

So a little update. I was thinking maybe I over heated the engine or something. I just drove it for 30 miles. I did the first 15 not going over 41mph. No issues. Another 14 or so at no more than 51mph. No issues. I gave it full throttle one time and at .3 miles it sputtered slowed down and died on me. Luckily after 4 or 5 tries it started back up. I then drove it home staying under 50 with no issues. I fill up with Shell premium octane V-power fuel. Any advice? |

Sounds like you may have a tank venting issue, easily fixed by drilling a tiny hole in the gas cap.
I also always recommend checking your valves when you have this sort of trouble after warm-up, or hard starting conditions.

Possible vacuum loss at high speed. Check for vacuum leaks as well.

It is obvious to me, that a PDI was not done on this scooter where you purchased it. If you don't do one yourself, this is just the beginning of your woes.
I feel you are pushing it too hard, for being new. Break it in a little easier.
Educate yourself about maintaining a scooter, there are all kinds of resources to learn from.
I agree with Jerry....those valves should have been checked before the scooter was ever started for the first time.
I agree with Hunter also.....at wide open throttle, fuel demand is at it's highest, and available vacuum is at it's lowest. Any leaks in the system will lower it more, which can lead to fuel starvation, a lean condition, and an excessively hot running engine.
Your scooter isn't as you stated.... "the stupid thing" or "the damn thing"...... it just needs you to understand that initial setup, proper maintenance, and riding style, all play a part in whether your scootering experience is lousy, or rewarding.

Thanks for all the heads up and information. I'm completely a newb to this and didn't believe I would have these type of issues after only driving it for one week. My initial plan was to drive it for a while and then once things began to break replace them with better parts. I didn't think I would need to start replacing parts 1 week into it lol.
I'm going to take it back to the shop I got t from and see what they say. I looked on the Chuckuslife website and one of the first things it says to do is to replace the fuel/vacuum lines so I went ahead and bought some.
I'm gonna drive it around my neighborhood today for a hour or two going 30 or less and try to get it to 300 miles so the engine is more broken in. Could this also be a carb issue? I eventually wanted to upgrade to a NCY 30mm carb down the road.

So just did a little research and the state law in Florida does not apply to scooters but there is a federal law that does apply. It says I should have 3 attempts for manufacture to fix the issue or if its been in the shop for 15 or more days I could submit paperwork to receive a full refund or new scooter under the federal law. Also states I could hire a lawyer and have the manufacture pay the lawyer fees if I win. Interesting. I'm taking it back to the shop tomorrow to see if they can fix it.

Another quick update. Did something similar to yesterday. I started at 134 miles today. Rode for 21 miles not exceeding 35 mph with no issues. I then drove 14 miles not exceeding 47 mph with no issues. Then went up to 52mph going 9 miles straight with ZERO issues. So this was really getting to me.
I then upped it to 55 mph and at around .8 miles it started the sputtering and slowed down to about 40-45 mph then the throttle caught and sped up. I then experienced several issues of sputtering between 48-54 mph. I eventually brought it down to 45 and kept it their for a while then slowly began increasing back to 52mph and had no issues all the way home.
I ended the trip at right on 200 miles so overall drove 66 miles this trip with the major issues starting at 55mph. So now I know where the trouble begins, I'm going to keep it 52 and below until the new fuel/vaccum lines come in. I'm also replaces the CDI and coil and should be arriving tomorrow.

Sounds like fuel starvation to me. Like mentioned before low vacuum = less fuel pumping action.

I'd bet a considerable amount of money on low vacuum at sustained high throttle position,,,had a very similar situation with a vespa et4,,

I'm still wondering about a hole in the fuel cap helping. It sure fixed my problems with fuel delivery issues last summer. Vapor lock or whatever you want to call it is more extreme with such small tanks, and high temps don't help.

A new 150 should not be ridden at over 35 to 40 mph for the first 500 miles anyway to seat the rings and valves. After that the valves and then the carb should be adjusted along with the break-in oil changed (some may require the break-in oil change at about 150 miles).
Before replacing parts or trying to run at over 40 mph for extended periods of time you need to break the motor in, get the break-in oil change taken care of, do the initial valve adjustment and then adjust the carb.

Speed doesn't matter when breaking in a CVT based engine. It has no relationship to the engine speed.

octane fuel. Still wont start.
