hard tapping at the top of the rear cyl

my question is can this be repaired without splitting the the motor? second question I have another motor that has cold rear cyl, I changed the carbs because I don't have a vacuum gauge, don't think there is a leak, checked for spark, I do have a spark. could it be compression? I also changed the black box bolted behind the battery seemed ok with spark.

I find it hard to scroll pages of post to find what I looking for, sorry for asking the questions that have already been answered before. regards john

thanks for your help

Sounds like an Automatic Cam Chain Tensioner failing. Easy fix. TOC brand makes manual replacements $50 per (2 on the bike). Manual Tensioner

If you're mechanical, you can convert the automatic tensioner already on the bike to manual. https://www.vn750.com/forum/31-engine...cct-video.html

replaced cam tensioner, still the same sound. pipes are really blue compared to my other bikes could the heat have ruined something at the top?
