Ok I'm getting mixed info on this one. I need velocity stacks for Hayabusa ITB's but not sure what size to get. 45mm or 46mm, I can find 45mm here for a good price http://www.truechoice.com/products.asp?dept=1025 but I can't find any 46mm. Will these 45mm ones work and if so what length should I get.
TIA

 

Those are really nice stacks but they are made to fit sidedraft Dell'orto and Weber carbs--they probably won't bolt on without some mods. Check motorcycle performance parts distributors like http://www.fastbygast.com
