CPC throttle body on M1000

[Passelat]

How do you guys think it will work with big TB on naturally aspirated M1000?
I am a little bit afraid off loosing some off the throttle response in my sled with those big TBs.

My engine mods is.
Speedwerx singel exhaust system
RKT head and porting
CPC intake
Vforce 3

I ride at 3000-4000feet

58mm Throttle bodies

Also interested in the large throttle bodies. I have talked BDX who also makes them and they claim on the 1200 kits they gain throtle response but I have my doubts. Any input would be great.

RacinStation M1200 Kit
Speedwerxs single & can
SnowPro Intake

there is always a down side, usually more top end=less bottem end. but with the mods you have, the stock throttle boddies may be too small so you may require the bigger tb's. I don't think they will hurt your throttle response much if you are properly tuned.

Thank you for your info.
Do you guys think it is worth the money?
I am very close to purchase these.
And what would you recommended, 56mm or 58mm?

the porting was done to match the stock TB's I'd talk to rkt first.

I don't think you'll see much loss in low-end response like you would with a big carb setup since you are not relying on vacuum to draw fuel.
