Cody, I looked up your carbs from the XLT and they appear to be the carbs that LC says to avoid... Maybe you 2 can sort out the difficult parts to find for these carbs and also there is a question as to the bell of the carb being smaller... Is this a big performance issue or is it just a visual thing???
The small body 34s have unique slides (idle stop and locating groove is opposite to the more common large body carbs). As such it may be difficult to get different slides for the small body carbs if the CA is wrong (as Cody has indicated).
The performance difference between the two carbs at WFO is probably small, but the large intake mouth looks kewl.

As Looney said.. ALL other internal parts are interchangeable (needlejets, jet needles, mains, pilots, etc).. The slides are the only "oddball" thing about them. I like the fact that they have a small "bell/intake mouth" as they look almost like stock H2 VM30's.
and I highly doubt there is any difference in performance between largebody and these? I dont see how? They both have a 34mm bore they are breathing through... If anything, it could be argued that since these are minutely CLOSER to the piston, they are more "responsive" than a larger bodied carb who's pickup is a bit further away? (just thinking out loud there..lol)
And I also doubt that Mikuni would make only a 2.0 slide for them, since sled guys are always "tuning" for the Nth degree of performance.. Im sure Sudco offers other sizes. I just never checked into it cause my bike runs fine.

). You can attend to this step/open up your intake tract at a later time too.....
What is the cost of your needles? I believe you have to work with a fixed needle jet too, which takes one tuning/jetting option out of the equation.
