Ok guys been riding and working on polaris atvs for 19 years now and looking for some info on the jets. I just rebuilt my 2000 400 Xplorer 2 stroke and went .040 over and shaved the head .015. In addition it has the 400 scrambler exhaust from the head pipe to the silencer. The silencer is an FMF and im curious as to what jets u guys think i should use to get more power. Any opinions are appreciated.
