Hey everyone so new member here I've be in the process of a restore/build on a '77 XS650D model, so far everything has been going well except for parts options. Specifically speaking the carbs, the bike has been in storage for 15 years since I rode it last. I replaced my intake boots and put new pod filters on the stock BS38's, carb rebuild kit, cleaned and re-lined the tank and rebuilt the petcocks. When I was rebuilding the carbs one of the M4x0.7 carb bowl holes stripped. I hoped for the best though and got the bike running again, but then a week later noticed the bowl was leaking. My biggest question is has anyone tried repairing the threads on BS38's with a Helicoil/thread repair kit? I have a feeling there is not enough meat on the carb to drill and tap to a bigger size or use a thread repair kit, I wanted to ask first before I spend the money on a kit to find out it wont work.
And if by chance it doesn't work what's the recommended carb option for a daily driver/street bike over the BS38's? I'm in Canada so options are limited and the search function on the site is overwhelming. But I can buy the Keihin PWK kit from XS650direct which looks to be the same as MikesXS kit. Is it worth even trying to repair the BS38's or should I just save some money and order the PWK kit? Thanks.
