Hi,
So my current carbs are in desperate need of a cleanup, rebuild and general overhaul of the internals. It's looking like I will also need to be replacing the carb joints, and I was thinking, is it not cheaper/easier to just replace them with something a little newer? I know this question has been asked, but I see most of the threads are from 8+ years ago.
So I have seen people mention VM34s as a solid replacement for the stock BS38s. I have also seen mentions of Lectron's and Keihin FCRs being great but expensive. Then ofcourse their is the TM34 from Topham/Allan's (depending where you are in the world) which looks to be an amazing bit of kit. Not sure if there is ever going to be a choice everyone agrees on, but hoping for some advice based on what I am looking for. I just want something that is going to be super simple to tune, easily accessible parts and reliable. Performance gains are an added bonus but not something as a priority for me. Should I stick with my BS38s, refurbish and rebuild them with as new a components as I can get my hands on? This of course allows me to keep my stock airboxes, all of the great guides on here for tuning them in the tech section as well as having Mailman's meticulously documented testing and tuning on his XS2 - but also means increasingly difficult to source parts. Are people that made the swap to VMs/TMs/Lectrons/Keihins wishing they had made the move years ago?
