I have an engine "kit" for a SV 650. It Will create an instant 10 hp -15 hp for your bike. It should give you a solid 75-80 rear wheel HP depending on how tired the rings are This is a plug and play type kit with no mods to the rest of the bike needed.
The good news is it doesn't create a fire breathing dragon just more power everywhere.
You WILL need to rejet your carbs but I can give you a pretty good baseline jet size to start with.
If interested please PM me ---and indicate if you want a ROAD or RACE kit.
