Who has done this? How have you done it? What tool did you use?


Thanks,

I used a air grinder with a fine grit sanding wheel on it.
Pull the carbs, look & feel the insides of the boots & use a marker where the high spots are, slowly grind material away & do several test fits.
The boots have a little slop on the bolts so make sure you get it in the same place every time when you check it.
Go slow & do several checks & you can get it right on. Make sure the O rings are in the grooves correctly when you put it back together.

 

did this give you any more power that you know of, or if you could feel it?

 

Seat of the pants, No I couldn't tell a diffrence.
The theory is solid & I'm sure if I'd Dynoed it there would have been a small gain.

 

about how much time did this take, do you think it would help a raptor with a pipe, filter, and jets.

 

It was about 3 hours total time (About an hour porting & matching them) I did it while I was adjusting the valves since I already had the plastic off.

Any time you improve air flow it helps.
My boots were as much as 1/8" off in spots & that makes a lot of turbulance.
With CV carbs the less turbulance the better!!
