Took awhile to get back to posting this, but just wanted to take a minute and thank Len for helping me with several parts questions and getting my order worked out. I ordered new vacuum plugs for my carbs, new gravity petcock and throttle cable from Len and they got here super quick - 5 days at most. I'm most appreciative of Len's generous sharing of knowledge and lending expert advice about what would work best for my 1982 XJ650. He's always very responsive with any questions I pose and has been so patient with me as I have a lot to learn. In the end, the going with the new gravity (non-vaccum) petcock and new plugs made the difference for my XJ. It's running so well now...I'm loving the ride! THANKS, LEN!
