Debridage et synchro carbu XJ600 Diversion

Hello everyone, following the botched derestriction job at the Yamaha dealership, I had to go back and replace the parts they forgot to change, and to see the mess they made, they managed to mess up the carburetor sleeve alignment tabs! Of course, they didn't synchronize the carburetors, so I had to do that too, which explains the length of the video! Naturally, this was done with brand new spark plugs!
