At about 10,000 miles I tried to get at spark plug when I checked bike over---following Kymco instructions, could not get to plug or get out, forced me to buy plug wrench from HONDA---but didn't pull plug out---figuring I'd get it out at 30,000 miles and maybe change/at least gap.
Right now while on ground on changing oil, saw (discovery) if you look in from left side you can see plug and probably with spark plug socket , get plug out to look, etc.=time saver.
My bike is ready for big trip when this virus thing slows down---fresh matching tires, new OEM belt, nothing falling off---In daily use right now, but going no place. Chattanooga in best of times is boring and expensive.
Impossible to get proper tap beer here at right price!
