jetting baseline


Overboost

Recommended Posts

so far, my machine is bone stock 87.

I am going to be doing some pro circuit pipes and k&n open dual filters. thats it.

 

what baseline jetting is applicable?

from what I been reading, it sounds like a 300 and a 25 but am not sure. want to get it right so I can go form there without making things go boom

 

my riding temp is going to be around 50-80, but I would say mainly above 60...mostly trails, some sand.

I dont like sand, makes the motor overheat.

 

I been reading alot of jetting options on here but just wanted to get some actual input before I take the plunge, not much room for error.

My wifes bike is exactly like you described and she is running 25 pilots and 330 mains. Keep in mind, every bike is different.

 

IMO the 27.5 pilot is gonna be too rich for your bike and make it bog down low. Lots of people on here with ported cylinders run a 25 pilot. I would start with 320-330 mains and go down if you need to...remember it's better to start rich and work down then to run lean initially and cause damage to your engine. Just my .02
