repost from CU, carb/ velocity stack ?'s

[sweetback]

First question is, I see 34mm mikuni carbs being sold on ebay, from sea doos and shit. They look like the roundslides. Are these the same ones that are sold for a yamha xs650?

Second question
I just need to know what size velocity stacks I need for stock 77 XS650 carbs. Anyone have an inexpensive resource for these? Or any resource really, may spend some dough on some cool ones. Will also take any suggestions or tips. Thanks all.

Of course, if I get the roundslides, it may change. Just need some help, thanks

There are some differences with 2 and 4 stroke roundslides, internal differences, slides, jets...Not a direct swap, but not rocket science either...
