So I am new to motorcycles, got an 82 XJ550 and have sunk a lot into it. I paid an elderly gentleman twice now who specializes in older bikes to do the carbs in August. I believe he did not change the throttle shaft seals but am not sure how to tell without taking them apart (he was hospitalized before he worked on it, and forgot to put some screws back after working on it). I don’t have any more money to take it back to him and now the bike won’t start up. Winter is here so I am winterizing the bike. When it was running I drove it a couple of times and when I was in my neighborhood, I had a new problem. When I pulled in the clutch the rpm would skyrocket. I thought the throttle might be sticking and double checked it and it was not. Only started happening when the bike was warmed up and the choke was off as well. I sprayed some starter fluid on the carbs and it definitely shot up when I sprayed the throttle shafts. Any advice would be appreciated. I love this bike when I ride it and now I’m not sure why I can’t start it up or keep it running without some fresh Hell happening.
