Comparing an aftermarket cyl that can flow substantially more a/f mix to stock cyl isn't really a good comparison.
You can get pretty impressive hp out of stock cyls with untouched intakes.
Shows how choked the rest if the cyl is...even when worked over
No HP difference seen in my experience . Vee shaped or not. Lots of guys put too much emphasis on the intake bridge shape imho.
I bet there isn't enough hp difference to accurately measure between any of those intake shapes. ..assuming the rest of the cyl work is the same
I'd recommend meeting up with some of the BHQ members who also ride at Dumont. They can provide invaluable advice . Especially if you run into jetting or trouble shooting issues,,or if you need setup help. Always better in person for that kind of stuff.
Last set of rear tires and wheels mounted , cost right at 35.00 to ship. I'd guess rears and fronts,with wheels, would be around 50.00-60.00 to ship, if I could put them all in one package.
