I am looking at doin something that hasn't been done already which will be hard or something that is not a very common swap. I have searched for 510's alot and they are hard to come by if they are not a pile of rust. I dunno. Like I said, I am in no hurry at all to do anything right now. I have a 1000 I can ride in the summer and I got a few cars I can jump into if needed.
