Hello everyone I am new on the forum and I truly need some help. I purchased a 2005 RSTD about 4 months ago and still haven’t been able to enjoy this wonderful bike. When I ride above 55 the motorcycle starts to swing for left to right. It’s not just the front it feels the whole bike is on a Seesaw and the front feels like it’s real light. If I ride fast it gets worst and I might lose control. This is what I have done replaced front and rear rim with new tires on both. Had them both balanced. I have tightened the head bolt by the triple tree. Jacked up the bike front feels there is no play. One thing I do notice is the front and rear suspension does not hold air on the shocks and my bike feels Like it’s not sturdy. I round from NYC to SC driving 55mph took longer by made it back ok but worried. I am long distance rider and I am really looking forward to enjoying this bike can anyone assess me with figuring this out thanks.
