So i bought a Kymco Agility 50 2015 and is a good scooter just slow is 50cc so i decided that i wanted to upgrade the kit so i bought a 80cc kit and installed it was buddy of mines it was still basically restricted and everything was going good didn't gain any MPH but i did get more Power still going 30+mph after about 2weeks something felt wrong ....next day everytime i used my brake and stop on a red light it would turn off ...so i put the idle on high and stayed on then about 1 hour later died on me ever since then never turn on i replace they CDI,Spark plug,Boss Drive,Bigger Carb,New battery and still nothing electric start and kickstart so i adjust my Vavle to 0.03 i think and nothing check compression was 150psi and still nothing so i wanted to check my piston and only in the middle is Dark not all around so i bought a new NGK spark plug and still nothing Sounds like it wants to Turn on but no Cigar .....so when i try removing the new Spark plug i removed it and All the Thread got stuck ....inside the hole i removed it i think the spark is not to strong cause is a 80cc not 50cc anymore Do you think i need a Bigger Spark plug and can you recommend me One ..was driving it and with the New kit only put 300miles on it
Sorry if my Spelling is bad i hope everybody can read and understand it Thank You

So you're saying you stripped the threads of the spark plug or in the head? If something strips, it's usually the aluminum head. There are repair options, but usually it's easiest to get a new head since they aren't too expensive for these engines.

Sounds like you need to tune the carb too.
