    After finally getting my Xj700 running again, I am on to rebuilding and deep cleaning the carburetors, have a kit coming soon. However, I removed my air box and want to switch to pod filters. I am curious if there may be a proper jet size I should change to as well to fit with that and what other adjustments I need to do.. its on an 85 xj700 so I believe they are the Hitachi HSC-32 carbs?.. Also want to thank everyone for all your help. This is my first bike and I’m still learning how to manage it as I go
