I own a 06 classic. I am trying to make the bike track correctly at higher speeds ( 80 -90 mph). I live in Florida, turnpikes average 80 mph. At 70 someone is trying to run you over. I have ask questions before on this forum, thanks for the tips. I did change the fork oil to a little heavier. Talked with 3 shops - Owners- experienced guys. They all said this would help little, they were correct. Several of the shops had changed front springs ( bikes are undersprung) and dampning, again they stated very little change, and not worth the money. I added Tru Track rear trans stabilizer bracket. That really helped. Front engine mount was bad ( 5k on bike ) Replaced it with stiffer unit. Worthless Dunlops replaced with Avons, much , much better. Am going to put on front engine link next. All this helped a lot, but problem still there. I purchased all the fairing parts to change from the bat wing fairing to the Road Glide unit. This with an inverted lip windshield to create down force at speeds. That should help a little more. I am trying a little at a time to correct this bike. Here is the real issue if you want to know the truth. Geometry of triple tree is beyond my understanding. Neck on frame has been extended on all our bikes. Pivot point on frame is in front of fork tubes. ( unlike any bike I have ever seen) I was told this was to make the heavy touring bikes handle better at low speeds with all their weight. It totally sacrafices handling at freeway speeds and slightly above. Does anyone know of a company that makes another triple tree for the touring bike. Is there any kind of a stabilzer ( like the sport bikes use) I can purchase for these bikes. Does anyone have any more ideas I can try, or is this an incurable issue on this particular bike.
