I had posted a question about banging under the seat when I hit a sharp dip.
Being this is my first bike, there is a lot to learn. Turns out it was the swingarm bottoming out against the frame under the seat. I needed to adjust the shocks firmer, plus I had installed lowering shocks and slammed it to much (making it a hard tail). Now all is right with the world (as far as my bike goes).

 

I'm fairly new too, and there is definitely a lot to learn. Thanks for posting, you probably saved me from making a panic post later.

 

You must have really slammed it, or hit those speed bumps at speed. With it that low did you ever scrape the frame? My Night Train was very low when I bought it. I never remember bottoming out the suspension, but I scraped the frame several times before I raised it up.

 

Ya I was hitting before I installed the lowering shocks, not knowing that the shocks are factory set for light weights. Then I slammed it way down, I'm 260lbs and still not realizing the shocks were not adjusted for fat asses, I had no suspension at all. And I did scrape the frame on tight turns. A lot of reading on this forum made me realize where I screwed up. And Like I said "All's good".
And my back is grateful too !!!!
