Topic: Flipped bike

[dcooksey001]

OK so flipped my bike on high end. Long story short not sure if the frame is bent behind the first cross bracket in the seat(if so I can chop it and make it a one seater) or if it's the swing arm. Any ideas on how to figure out where she's bent at?

Center stand? If so, prop it up, use multiple levels and plumb bobs and tape measurements. If you want to know exactly, take it to someone who has a frame jig and have them verify it.

How do you "flip" the bike. Are you OK? How did it happen?

What model bike and year do you have?

I had a buddy who bought a known-good frame with papers and transferred all his good bits onto the frame over a 2 week period while taking a full engineering course load in college.

If it's a Sandcast, well maybe it's worth fixing - but if you want to ride, have you considered a visibly straight, good frame with papers?       The cost to replace could be less than the cost to repair.

I've bought frames in the $200 to $400 range.

Had a dog run out in front of me, luckily I was able to swerve and miss it,  but hit a ditch line doing about 65-70mph. Fractured spine and a few fractured ribs but nothing too major

Well it's actually my newer bike (2000 Honda nighthawk 250) my 72 500 (mostly rebuilt by threads here) is my main bike, but I love how snappy my little 250 was lol

Is there any visible damage? Are the rear shocks still plumb? Is the tire (rear) tracking straight?

Lay a long metal straight edge along the drive chain, and slowly rotate the rear wheel so the chain travels. Many of these examinations you can do yourself. Glad you're alive and well after your accident.

I'm thinking when the tail end hit the ground it bent the back of the frame to the left a little but in can't tell if it's bent at the back of the frame or ifnits the swing arm

Swing arm "legs" do bend pretty easily. Also, the top mounting stud where the shock attaches can also get tweaked. You're going to have start doing some inspection to help isolate if and where...
