My 650L has tried me and is a proven money pit.
Over on Thumper Talk a potential buyer asked about the things that can go wrong with them. One fellow avoided the usual response of "as reliable as a rock" and rattled off about 8 things that break on the BRP. I had everyone of them plus the two melt downs. Other than that they can be good.
Off the top of my head the things to worry about:
CDI - lowest bidder made them.
Pulse Generator - another low bidder
Stator
Strongly consider an oil cooler (http://suttoncycleworks.com/oilCooler.html) or change the oil every 800 miles.
Moose Racing 650R front sprocket to protect the counter shaft from excessive wear due to the lack of a cush drive
Sheilds for the cases to protect them from being punched by the shift lever or rear brake.
I had all sorts of problems with my carb because it sat so long while being rebuilt (cylinder liner was under sized from the factory so when it got hot it would not maintain good contact with the cylinder so it couldn't transfer heat and it would melt the piston annd burn all the oil - no fun). A session in a ultra sound cleaner was the final solution - highly recommended.
Rejetting the idle jet is worth it. The rest, meh, I'm not convinced. Your mileage may vary.
Good luck. It can be a fun bike for sure.
What is the story on the bad frame?
