1984 TT600 auto decompression question
Hello, I'm new to your forum and I have a question about the auto decompression on a 1984 TT600. I have adjusted the decompression cable freeplay to .5 mm as instructed in the original Yamaha manual with the engine at top dead center. The valves are also adjusted correctly. The bike has a ton of compression and runs very well but it is very hard to start because the auto decompression only works some of the time. Its as if the decompression lever pulls back at the wrong time during starting. Any ideas? I just purchased this bike and its in great shape except for this problem. Has anyone here had this problem? Thanks.
