Alright, I’ve posted before about my bike revving out while trying to tune the carbs, but I’ve just never heard of anything like this happening and I can’t find a solution anywhere.
So regardless of the jets I use, if I richen the mixture, the rpms slowly increase to around 1200 or so, and if I richen it more than that, it jumps up to like 4500 rpms instead of bogging out.
Does this sound like it would be a Would this be a timing, points, or mechanical advance issue, or maybe weak springs at that point?
It’s a 78 xs400E
