Reply To: MOT Day and running issues
Mixture with size 15 pilot jets – 2.5 full turns out front and 2.75 for the rear as its a 125cc and leave this forever (no matter what mood she is in)
If you have 17.5 pilot jets (sometimes Korea does this but not all GV’s have it, and tbh 15 is correct size as all GT125 Comets use Aquila engines too , with factory 15s every time i fix them they always have 15s in.) , i am digressing, as i was saying if you have 17.5, you will be hovering around 2 full turns to 2.5 turns max usually. , less than 2 will overheat the bike even if it runs better lower. No true number of factory turns were revealed as korea sets them uniquely even so much as 1/10th of an turn less or more on each bike they test and ship out.
Trust me when i say if the slides look fishy, just replace them. bad ones or worn down slides would cause fueling issues and sometimes it won’t idle properly as a slide is stuck or not fully closed down. Another thing is to check the slide needle isn’t on fully lean setting or fully rich setting, you want to be in the middle if there is 5 grooves , then as the bike gets better, then enrichen it one step down towards pointy end.
Old age is the enemy of rubber slides but sometimes its just last keepers using E10 then letting the bike sit for months rotting, so it degrades things further
