I am looking to balance my carbs on a similar SECA 900. I thought that the YICS requires that you plug the channel that balances vacuum across all carbs. I read that you will get the same reading unless you use the tool to block the individual YICS ports???? How did you make out without doing that? DId it run as expected?
You got me thinking now, that was a while ago, and no I am not satisfied with the way it is running. The float is sticking on carb one and I have to remove them again and I will balance them again and check my manual for that. I think you may be right. thank you B
You are right, my memory fails me after 40 years. I just checked my shop factory shop manual and you do need the special tool P/No 90890-040681 to block off the YICS. I will make one or see if I can find one and add it to this video. Thank you.
Thanks for the vids. I got a 4BB last year and needed to rebuild the carbs. The vids are good to see parts of the bike that I did not take apart. Always good to know what is inside. before taking it apart. My interest was in balancing the carbs. Will try it as soon as the weather improves.
