Valve Ajustment?
« on: October 31, 2012, 05:50:25 PM »
I'm about to adjust the valves on my Agility50. I need the "factory gap specs" for the valves intake/exhaust? Also any tips will be helpful! It will be my first time doing this allthough I'm very understanding of how and what I need to do. Thanks!

0.04mm for both sides but make sure you warm the engine up 1st before you adjust them.

I was always told the exhaust valve should have a slightly bigger gap as that gets hotter due to passing hot exhaust gasses so expands slightly more than the inlet valve, also that it should be done when the engine is cold preferably when it has stood over night, if you adjust them when the engine is warm you are adjusting them so there is a gap. If it's done correctly the idea is there will no no gap once the engine is fully warmed up and everything has expanded that way no tapping noise but not to tight that the valve can't fully close onto there seats otherwise you risk burning them out......

Thats why I do mine in the mid range of .03 for that reason. that way you are safe all around. My scoot is a 07 and I have been doing my own tunes my self.

i always do mine when cold as the gap is to componsate when the engine is warm. metal expands thats why the gap is there. but my gage only starts at 0.05 so i do it on that but a little tighter. not best solution but works for me. will have to get another gage that starts lower.

Yeah, sorry, your right, do it when COLD. Too many threads at one time while at the same time im getting f.b messages and txts on my phone  :D

Zombie used to do his on a hot engine im sure and set them so they touched that way when it cooled down he had a perfect gap.

just make it a regular thing you do. Twice a year is good. or when scoot starts hard or you notice a dif. in how its running.

Thanks for the help everyone I'm just about to start but it looks like I may need to run to the store for a lower feeler gauge because the one I have goes to 0.05mm!! Wondering if that would be close enough?

Guess I could do it like that Skippy seeing as how I have the same deal with feeler gauge!?!?!
