Ng a buddy, but I'm not sure how mechanically inclined he is. I should be able to go take pictures before buying. Thanks
This is my old pre-ride bike checklist. I haven't had a chance to really update it or make it pretty. I made this about 4 years ago. So maybe it'll provide you with some of the things to check. Your friend could probably find a better list online. I have other things I check out whilst examining, and also can tell a few other things during the test ride. But dont have the time to re-review
Electrical wires (any chewing or other obvious wear) + working lights (headlights, highbeam, turn signals) & horn
Chain (dirty, slack, tight spots, can you pull off rear sprocket edge, side sway)
Sprockets teeth and overall condition
engine oil (how dirty, the level, any condensation/milkyness)
Fuel tank (dirty, rust, etc.)
hoses and anything rubber (cracking, dried out, etc)
Fork Seals, Forks, Shock (cracked/dried, leaks, excessive pogo'ing)
Tires (wear, ratio, type, age, dry rot, etc.)
Title/Registration
Tool kit
Trunk and seat removes easily
Owner Manual
Coolant (level + color)
brake fluid (level + color)
levers/pegs (any bending)
missing bolts/screws
throttle return
check for any scratches/cracks on the fairings, fender, exhaust, levers, bent rims, etc.
before and after ride, check for leaks (if they are trying to cover something up by wiping it off, it should reappear after the ride)
leave the bike on while you do the pre ride check. On but engine not started. Take your sweet ass time checking the bike out. If the battery is going out, the bike being on the on position with screen lit up might sap enough voltage from the battery that it wont start. When you bring the bike back, cut the engine but leave all the lights on again. Do another review of the bike and try starting again.
Edit: of course check all nooks and crannies for rust.
amount of keys available
confirm if ABS or not. test if working by stomping rear in low speed to see how/if locks up
Questions to ask (also take note of their tone and how they answer, in addition to what they answer with [which could be poppycock]):
*leave the bike cold for you (some issues kind of get muted when warmed up)
*main purpose used, commute detail
*reason for selling
*maintenance schedule/records
