Friend of mine likes what I did to my ultra's motor(103,255-cams,ported & valve work on the heads. He wants to do the same but being that I did the heads with the rest of the job I couldnt tell him the differance. I've always known that the v-twin motor is like a air pump fast air in fast air out. Would this be something he should add to his big bore job?

 

There is certainly a ton of usable power to be had from a good set of heads*, from what our 27 yrs. in business has shown us, on the dyno, flow bench.

 

Me personally, Was thinking of adding a 50mm throttlebody to my equation. Good or bad idea?

 

Well I run a dual runner intake 50mm setup on my 97" Twin cam setup and its an excellent match, but I'm also hard on the throttle and take the rpms high on my ride constantly where some benefits are seen. What are your running currently for a TB/Carb?

 

The stock setup for 96 inch. fuel injected.

 

I like the welding and cnc porting that R&R Cycle does. They choke the ports down 30% and install a 1.900" intake valve, those heads rip!

 

Baisley heads will run with the best of them have been for many years.
give JD's a call at 610-297-0321 he wil give you a package that will surprise you.

 

Agreed here, shop with a great rep.........

 

I agree about Baisley, have whitnessed his heads on the race track many times, he is the best (on the track). Just did a Baisley to R&R head swap on a local bike for Dennis Crane and he is amazed how much quicker his bike revs with the head change only.

 

maybe if you use similar heads the results would of been diffrent....
