i've struggled for a few weeks with this atv. i realized last night that it was running rich. i adjusted the needle in the carb. it is running great now. how do you know what the right/wrong setting is??

 

lean it will rv but no power rich it will thend to die check out my "url " it will help your jetting needs or gassrx.com

 

seems to have good power. I saw your site. looks great. printed off the "problems of jetting" the other night for my neighbor(he has a friend who is buying a brand new yamaha and feels that it needs jetted) My dad was a mechanic all his life and I kind of agree with him. You can do alot with stock!

 

right/wrong~~ plug color is how you know.
The LT is jetted fat from the factory. If the needle adjustment worked (running fine) then that's great.
FYI: You can go DOWN a jet size (90) w/o problem. [img]i/expressions/face-icon-small-smile.gif[/img]

 

plugs can lie to , race fuel can sling lead and prematurly color a plug , read the pocelin /ceramic it should be a nice cholate light brown, the outter circle should be the same not wet
