I an in the process of converting my YZ400 for enduros. I am considering buying a FMF powercoreIV2SA and wanted to get feedback on performance and any necessary carb. adjustment. I am also debating on weighting the flywheel because most of my riding is in tight woods. Any experience/feedback on this would be greatly appreciated.

I run a '99 YZ with a Ty Davis 10 oz. flywheel weight.You cant beat this mod for smoothing out the hit of MX bikes.It also helps with stalls at low speeds.
I dont know about the FMF pipe.I have the DMC(dave miller concepts)pipe which gives you a nice grunt off the bottom.
Go with a skidplate and aluminum handguards also.
