AH OK. I know EXACTLY who makes those. I dont know the link itself but in the online sources list here on the site, look for cycleX. The set will run you about $500. AND may require some frame mods. I know some have done it without mods though. If you get them, get the phone number for Ken, he is the owner of cyclex and can help you with some tuning issues.
Not to detract from these carbs but you may have better luck with a set of CR carbs. but those are even more expensive.
The ride IS the adventure. The destination is just to get gas!
