These were done by Zoran at TWF. They are bored out to 42mm. If you were to send him your TB’s it would be $350 just for the work, after shipping to and from your looking at about $375-380. Not to mention the cost of the throttle bodies themselves. $300 shipped seems fair. Please PM me with questions. Sent from my iPhone using Tapatalk
I bought them used from a guy on SV rider back in 2014. They have been used and work great. The secondary butterfly mounts are still intact with plates removed. Sent from my iPhone using Tapatalk
