I got this kfx from a buddy that has a White Bros muffler no airbox lid and is susposed to have stock jetting.
I need to know what jets are stock and what is recomended for the pipe with no lid.
Right now all I know is the pilot jet is plugged starts but wont get off idle.So if it needs a bigger pilot I wont mess with cleaning this one out.I havent gotten it off yet to see exactly what is in it just dont want any surpriseses.

if its stock jetting it must run like crap. stock should be 130 main 22.5 pilot .
i would like to think the jetting should be 150 main with a WB pipe and no lid. you may have to use a #25 pilot but time will tell

 

170 main here in michigan

 

Thanks.The guy that owns this has everything messed up.What air setting does this ussually need?Set at 4.5 turns out now and it still pops on deceleration.
BTW it has a 135 main stock pilot and I couldnt read the intermediate.

 

what does your spark plug look like? black?

 

Heck I cant get to the plug yet.Not sure if I can get a wrench into it.It was too hot to mess with after running.
Once I get close to the right jets in it I will try a plug check but right now the popping on declleration is more of a concern by it being lean.I could live with a little rich.
This bike has had maybe 4 tanks of gas through it but the owner put a WB pipe on and didnt know sqawt about how to jet it.Then to top it all off he pitched the stock jets and the airbox lid.

 

you could ziptie a piece of cardboard ( to close the airbox) till ya get the jets
i seen lidz on ebay for $5 already. (prob $20 shipping lol)

 

pilot screw 2 1/4 turns back

 

on the Dynojet kit, they recommend putting your needle at middle setting (#3), turning screw 3.5 turns out, and the main jet should be 150 (I'm going from memory on the mainjet, but the other 2 are accurate info). this is open airbox configuration, with aftermarket pipe, below 2500' altitude.
