hi all can i install this sittings for a stock atv with only aftermarket pipe because i have a pipe and thear is instraction in it for adding any aftermarket things :
and the note say this recommandation .

1- REMOVE LID FROM AIRBOX.
2- 190 MAIN JET.
3- 40 PILOT JET.
4- #4 NEEDLE POSITION.
5- 3-3.5 TURNS GAS SCREW.


so for this setting do you think that it wont damege the engine

 

Sounds pretty good to me, but thats for low elevation.(2000ft and under)



Biggerisbetter.

 

Make sure that's a 190 dynojet jet. A 190 mikuni would be too big (imo)
-T

 

sounds a bit rich to me, ive rejetted mine many times with many different mods, id guess the best setting for you would probably be a 185 with the needle clip 2nd or 3rd from the top, try 3rd first.
