XT600 Advice/Questions

[barbeque600]

Hi everyone, this is my first post here. I'm looking at buying an '84XT600. They seem like solid, great bikes. This one's in pretty good shape, guy says it has some very minor oil leaks that can wait 'till winter to fix, and that the carb drain screw is leaking also- but only when parked and full of fuel (he just shuts the gas off to avoid the leak).

However, this past weekend he rear ended someone before I had a chance to come look at it. Just a small bump, and laid the bike down. Says it's mostly just plastic damage- the plastic around the headlight is cracked, signal lights, and cowel cover. That's not a big deal to me, as long as it's still functional- plastic weld would do the trick until I get around to replacing it.

He also bent/twisted the shifter. How much of a problem is this? He said it was bent enough that it's hitting the case a bit when up-shifting, making that difficult.

So, questions:

How much of a problem is the shifter? Would it be able to be bent back, or would it ahve to be replaced? How hard/expensive is it to replace? Could it being bent like this cause other problems or indicate other damage, aside from the lever itself being bent?

Also, is there anything I should look out for with these bikes, common problems? Anything in general that I should check out when I go to see the bike?

Thanks in advance, and have a great day.
