XS650 Addict
Hey everyone,
I've been in France for 4 months for work, but I'm home in a little under 2 months so I've started thinking about all the fun things I want to do to my bike. It is a 1980 XS650, btw.
Anyways, I rode it around before I left and it runs great except for aluminum bits in the oil filter, which I believe is from the cam chain guide wearing out (there were also black plastic bits in the oil). I know this normally occurs around 20K miles, so it makes sense.
Anyways, I'm going to tear the engine up when I get home and while I am in there fixing replacing the cam chain guide I figured, what the hell, lets do other stuff.
So, here is my list of things to do. Please advise me if you think something is missing.
The whole point is the most HP for the buck (with the exception of the PMA).
1) I would like to put larger pistons inside. I believe 4th oversize is the largest? If so, where do you suggest I purchase them? I have been told Gary Hoos racing is top notch.
2) PMA. Hugh sells one for 319 and MikesXS for 290. Can someone chime in on the difference.
3) Possibly different CAM. I've heard of more aggressive cams that are simply drop in. Perhaps a Shell #1 (which I've heard can also be purchased from Gray Hoos).
Thanks in advance,
Adam
