First I have to apologize for my english because I am from the Czech republic. So my problem is...I bought used LS 650 PV itīs US version speedometer-miles.... I got some documents with operating data so this bike might be 1997 version. I checked some web sites and compared all what is typical for 1997, serial frame number(VIN)- yes itīs realy LS 650PV but I am not sure about the engine. For exapmle carburetor I was surprised because since 1995 Savage has carburetor with horizontal drain plug
and my own has vertical. I have started to be afraid... I bought bike with an old engine?! My question is what is typical for engine made in 1997?Do you have any ideas how can I know that? I am looking for chart with engine numbers there should be my answer. Thanks for your help Michal Krska
