I bought my first motorcycle a couple of months ago. I paid $100 and put another $500 into it to get it going. It still needs some work and I think I'll redo the whole thing to get it looking and running better. My main question is that it's a 1980 KZ650 E1 LTD. This is a ******* model. Can the parts for a D or F model work as well? I'm especially worried about the carbs.
