Does anyone make a high output VR and stator for the older 800…specifically my 08 ? If not, is there a way to modify the system to except a newer style VR or stator?

I’m not having any problems right now, but I’m thinking about some "upgrades" that will likely cause me some power problems. I’ve done a little searching and didn’t see anything for my old girl. I’m trying to decide if I would be better off just upgrading my stock battery and adding a 2nd battery with isolator, or going HO on the VR and stator if I could find them. But I’m still curious if the stock charging system would be able to keep up with the demand on the 2nd battery if I went that route.
