Dennis:
Rode to work today and it ran the best since I bought it. Warmed right up, smooth idle... smooth at take off. Thanks you very much!!! Not sure what I would have done without your knowledge and help. I was going to get a local shop to tune it but they wont touch a bike this old. My expertise is Snook fishing, if you are ever in South Florida I would love to return the favor. I just got back in from taking a friend from out of town and here two kids out fishing. Her Daughter caught her first Snook (29 inch keeper)! You indicated there was a neat trick to improve the bottom end...but never explained Yes! "want it to go better yet ?" What is the trick?
