my vibe 50 2t is totally failing. Strays perfect every time no problem. Could idle forever if I wanted it to. The problem starts when I put pressure on the bike. Eg; going up a hill. Two people on it. I'll have it on full throttle and it will b all good. Then go up a hill and it just slowly Boggs out. Within 30 seconds it's bogged to a stop (still running) still on full throttle but the bike has no power and is making a rank bogging noise. Still idles fine after this.

My guess is worn top end. Piston/rings may be worn out making low compressionDo a compression test. It should be over 120 psi. if good. 90psi will run but not well. Less than that you are lucky if it runs.

My dick head brother put marine oil in it. Would that effect it? How do I compression test it. An if it is what u said is it worth fixing
-
There could be too much oil. That would reduce power as well.
Scooter Compression Test How To (http://www.youtube.com/watch?v=l_RMl5IIenA#ws)

Would the fact it was marine grade oil he put in it screw the scooter?
-
Btw I really appreciate u trying to help me.
-
Marine oil for a tank or two isn't likely to damage the engine badly.
Tell us more about the scoot. What kind of miles are on it? Have you check the CVT components? If it's happening only under a heavy load then I would strongly suspect compression (as Zombie said) or transmission work. If your variator is worn it can make the bike run like a frozen turd. Also the torque driver should open smoothly without any binding or wobble in the moving pulley.

I don't know how to check all that stuff haha. As I said I'm a major noob when it comes to scooters. Ok it take about 5 mins to get it started the first time. Then u can turn it off and start it straight away after that. It's not just under pressure. It's basically when it's warmed up after about 5 mims of riding it. So after 5 mins of riding it,it will be at full throttle (not full speed) and all of a sudden all power just dies. It takes between 20-30 seconds for complete power loss. While I'm still holding the throttle on full the bike isn't moving but it hasn't turn off. Maybe it's getting too much oil or something? It has 4778 kilometers on it

Too hard to say w/ out the basics. Lots of things can cause this... Start at the bottom of the pile, and get a comp> test done. Any "Mechanic/Shop"
can help you out on this for a few quid. If I had a scoot that did as you describe... That's where I would start.
Ps... Don't ask them to fix it, Just ask for a compression test. 5-20.00 bucks if not free.
-
What is compression test tested on. Like what part of the bike
-
Oh God!
-
Were you able to see the Utube link?
If not go to utbue, and look up compression test. It is the amount of pressure the piston creates inside the cylinder head. Low pressure=what u got, maybe.
-
Ok. So would thy explain why when the bike starts and it's cold it's good and runs well with full power then all of a sudden its power drops out and there is none
-
Just pulled the scooter apart. Would the fact that the air filter foam having oil al over stopping air flow to the moter cause this problem?
-
Also where is the auto Marie choke on this thing.
-
Just cleaned the spark plug and air filter. Now just sitting on the stand and putting it on full throttle it cuts in and out. Like goes full power then cuts down then picks back up.

That will do it.

The carb. may need cleaning/adjusting. If it is jumping around rpm's you may also have a vacuum leak somewhere. If your intake filter was clogged the scoot will try to pull air elsewhere. This may have sucked out a worn seal, or the coupler that mounts the carb to the engine. Sounds like your scoot needs a through going over to know what is happening. Do you have a scooter shop anywhere near you. Some shops will "hook you up" if you mention the forum, and "advertise" for them.
Jpreston has a running scoot, and he still wonders what the hoke under the seat is for.
What Would Happen If You Fell into a Black Hole? (http://www.youtube.com/watch?v=gLMiJQXsmkc#)

Mate I cleaned the spark plug and pulled the head thing off that the spark plug is screwed into. Wire brushed all that up. Cleaned the foam from the air filter and also put a hose back on that fell off a while. This hose is about 8 cm long and 3 cm in diameter. I think it's some sort of air hose. Anyways put all the bits back together and scooter is running smooth as again!!! It's fixed. For now anyways. Thank u so much for all ur help. I really appreciate it. Cheers

that's terrific... Cant say I'm not surprised too
