Welcome to the GWOF Cruzr My son has an 82 GL1100A he rebuilt his 4 carbs last year
and balanced them.I sent him your question okay. He's a journeyman MC Mechanic amoungst other things. I've been encouraging him to join this site because of his extensive knowledge but I don't want to push him, he's a very busy guy.
Thanks bstar for forwarding this to your son. The bike sat for 17 years in a garage. I polished her up like new and rebuilt the carbs last year. the #1 carb has no vacuum. I already checked the compression,and it passed(though maybe intake valve was stuck)
