250r lost bottom end
I recently rebuilt my 87 R and I put on a fmf gold series pipe that the guy who gave it to me said it was a bottom to mid pipe and I believe him. I also installed a vforce reed valve and cleaned up the carb, k&n and put an outerwear on the air box lid. I now have lost my bottom end power and have to stay on the pipe to get around. It feels like a banshee but with 250r top end. I am trying to think of anything i could have done wrong other than the pipe is a top end pipe. Any suggestions would be appreciated.

Your pipe could be the problem. FMF makes a variety of pipes for different applications. If you wanted bottom-to-mid range you should have the "Fatty" but it sounds as if you have the top-end SST. I have the Fatty on mine now, used to have an old FMF top-end pipe, and I can certainly tell the difference.
