I got everything on the 400 today. It fired right up and runs real good. It definitely pulls harder. The front end seems lighter now too. I'm running the 270 main and 30 pilot. I hope to do some good hard riding next weekend to see how it does. I noticed when I put the spring in the secondary that the buttons were absolutely detroyed. What would cause this? I've got less than 100 hours on it. I like to jump a lot could this be part of the problem?[img]i/expressions/face-icon-small-confused.gif[/img]
