Thanks, I took it to the dealer for a good checkover and tune up and asked them to look at the problem. Mechanic said he rerouted the cable but he also removed the risers while he was at it. I noticed on the MG Cycle site, there is a note that the current cable for that part number is 4" shorter than the original so I am wondering if perhaps the previous owner may have replaced the cable at some point with a shorter one. Perhaps I'll just reinstall the throttle side riser temporarily to see if the cable routing change is any better.
