07 Fx cuts out when I Pin the throttle?

Yamaha dealer.I dont remember what specific grams but you will at least need the short steel ones int the tips.It is a trial and error thing.They are cheap.
 
Well thanks for all the help, turns out better put my helmet on and ride the short bus cause it was just leaning out cause of a low fuel condition! I suppose when i hit her hard everything moved to the rear and it was suckin air. I watch the rpms after i filled and 11500, 11800 most the time did hit 12 one time only. I new it was something else when it started cutting out more and more on less of a rpm. Man I need to quit working shift work my brain is getting mushy. Thanks for all the help not I know what to mess with later in life. Great forum, cruise it alot.
 
I'd take an easy fix like that anyday!
If i remember right, mine ran at 11400-11600 last weekend? Bone stock.
 
That is the easiest, and best fix yet. At least you did not tear the sled apart trying to figure it out
 
ulmers clutch kit requires you change the secondary spring - i think it's b2 (dont quote me).

yep that's where mine is. no rev limiter either.

not sure if you need to do anything to the secondary unless you change track. (length or lug height)
mine was fine when i had my stocker in.
