Hi Johnie,
That's a great list to use as a guide for me or others to check when going to look at a prospective cycle purchase...or after the purchase.... The best deals I've found are Present Owners who might know only a few of those things but it's up to me to REALLY eye up the bike face to face and possibly get permission to "pull off a few parts just to inspect.." sometimes the seller will let me
I think most sellers where you can get a 'smokin' deal from tend to have just 'dumped' the bike in their own perspective but try to make it sound like they've cared for it
. I just hope that the OP takes a close inspection of the bike and the things you mentioned,maybe even carry that 'list' of items on a sheet of paper w/ him while he checks out a prospective cycle.I know that those things are things that'll cost him $ if they haven't been done right in the past.
The only other thing I would add to that list would be to get underneath the bike (flat on the ground
make sure to take about a 6' x 3' piece of rug,etc. w/ you)and inspect the lower frame/engine cases for crash damage or rust.
