funny, if you search the recent posts another guy just got a 650 custom and he does not like the stock foot pegs and was looking around to buy a set of those foot boards you got (they are stock on the 650 "classic").
ditto on the pipes and the jets on the carbs. The stock mufflers contain baffles and a catalytic converter, so that bike is going to be running lean and hot unless the jets have been adjusted. If you put something more like the stock mufflers back on, you will have to put the original jets in the carbs. If you havent asked the previous owner and you still have the chance, find out for sure what he did. Its not a bad thing either way, you just want to (need to) know whats in the carbs now.
some people get confused on this. With fuel injection and an O2 sensor you can modify the exhaust and intake, and the bike injection will adjust itself to run the right mixture. But with carbs you have to match the jets to the airflow on the intake and exhaust.
it looks great with all the chrome on the engine and transmission blacked out. If you are not familiar google photos of the Custom and you can see what it looked like originally.
