I have read about every forum on here on this issue so I'm not taking the easy way out. Does anyone know with scertainty what the stock jet sizes are for an 81 XS400 Heritage Special(believe its a heritage special this is in debate too, Its stamped with the 4R4 which I believe means its a HS)? I pud pods on and need to rejet and like the rule of thumb one up for each mod. My problem is I have no idea what the stock size is as the manual could be wrong and everyone has different theories. I have decided to purchase two sizes higher but don't know where to start. If anyone has pods and stock exhaust and they have found the key that would be awesome too. Sorry to keep revisiting the topic but I havn't found a clear answer yet.
Thanks
