velocity stack size

i have two on my triples that are different from the others. Is this going to be a serious problem until my new ones come? they are .5 inch smaller than the other 4

I am certainly no expert, but personally I would try to make them all the same. Pricey little things from what I recall. Some people have suggested that running 3 short and 3 long would give you the "best of both worlds", but it just seems like a bad idea to have different cylinders having different power outputs.

 

Longer horns from what I understand give you better low-end torque. Shorter ones give better top end power. I have not tested this theory, but it makes sense in my head

 

That being said, I don't see it causing any major issues in the short term.

from what I understand from carb'd Porsche's, this isn't quite correct. If I'm not mistaken, there's actually a point where much longer air horns are better for high rpm applications....I'd have to pull out the book again to find out for sure though.

 

and no, I don't think it should cause any serious problems for a short while.
