i was going full tilt up a super steep hill today and there was the POP but a loud pop and the scoot lost power so i had to pull over. Its still starts and drives fine but when i am going up hills now its as if the engine is choking.. like completely losing power for a few seconds then powering back up again do you know what it could be ??
Bike is a puegeot 50 cc vivacity

I know what you mean with the throttle bogging at WOT, that's a carb issue, too much fuel or too much air, since you said it banged at WOT going uphill, I suspect too much fuel is being delivered (running rich). Check if your air filter is clean, and try adjusting the A/F screw, also, check for vacuum leaks, you can check for vacuum leaks by spraying carb cleaner on the hoses and joints of the carb with the scooter idling, if you notice a change on rpms at some point, then you found the vacuum leak. thanks so much for all the replies i can try to do these things but will i need any specialist tools or will a philips screwdriver be fine for the most part im not to clued up on how to do these tasks but id rather tackle it myself than pay fortunes to some spanish geezer |

Thanks so much for all your replies! yeah im fairly certain the bang came from the exhaust. And i rigorously tested it today.. the bike starts perfetly on the kick.... it ticks over lovely but after test on different inclines including the flats.... i have found that after the throttle is opened half way it starts chugging.. like as if someone is turning the power off and back on again its very embarassing but if i keep the throttle less than 1/2 open she drives beautifully....no smoke or oil or anything like that although after the bang yesterday i did notice a sort of burning smell... so i was thinking it might been a backfire.... im inclined to think it might be fuel delivery related.....
keep your suggestions coming and thanks one again!!!!!!!!
p.s the bike is completely stock is a 2002 puegeto vivacity 50cc (spanish plates) and is ridden in Spain
Thanks
