Can u realy tell a big difference in throttle response

 

[YAMAHAULER]

I can't remember I run a 07 yfz 450 carb
It helps take the hesitation away when stabbin the throttle fast

Wat all do u have to do to put a yfz carb on one

 

[YAMAHAULER]

you need a custom intake built to bolt to the head for it and some tubing,clamps
and unless your motor is built up the yfz carb will be too much carb for a stock motor

Ive got a yoshi clamp on k&n wld that work wit a smaller jet

no dude not really. It would be a too much carb and not enough motor situation.

if you went to a 366 or so and bigger cam etc you could probably tune it down but thats still pushing it

Ed's is a 357 with I think a S1HC and a HMF slip-on.

Correct and it is just a tiny bit too much carb yet for it at times until I P&P the head and throw a bigger cam in that is:nanner:
my comp is just under 11:1 also
