I read some anecdotal stories of difficulty in synchronising with the three drop rod throttle linkages that seem to be the only choice for conversion kits. Instead, I opted for the Webcon bottom-mount linkage, as I wanted to keep the top of the carbs as clean and uncluttered as I could. As with anything, there are tradeoffs. The bottom mount linkage is easy to work with on the bench, but in place, it presents access challenges. All in all, I'm happy with my choice and don't plan to change.
