Whats the pros and cons? Many of you are running your quads this way. Please tell. TIA

 

Why do you need larger pilots when the stock pilot jet is within range of adjustment on the screw?? I have never had to open the pilot screw more than 1/4 turn on even the most built engine.

 

Raptor720,
I changed mine because I couldnt get my bike to run properly...tried the 25's a little better but still would stall on me...put in 27.5 and now its workin with the screws, unless I just wasnt getting it dialed in...it seemed when I opened my airbox it made it lean all across the board...not to mention that my floats were at 9 mm. I am just curious why you wouldn't need to change the pilots? Dyno jet says the same thing but when I told them my airbox was open they said they couldn't help.
