Rebuilding my 74 dt250 was created by D7A1Ndt1e
Hello all!
I recently acquired a non running parts bike. I measured the compression at 75psi but I can get the bike to start. So I've decided to rebuild the engine to get the bike running instead of using it as a parts bike. I started pulling the engine apart but came it a hault when I got to the flywheel. Can you tell me how to remove the flywheel? Normally I'd see bolts or screws on the Fly wheel holding it in place but this engine looks like it has rivets. Any input would be greatly appreciated!
The top end is shot and will need a piston & pin, rings, and bearings. I'm also going to use gaskets. The last guy who rebuild the engine didn't use gaskets and didn't clean the surfaces. I'm very surprised I was able to get it started with the internal condition of the engine.
Please see attached photos of what I'm working with. I will be using a fly wheel puller. Thanks in advance for any helpful input!

I can't figure out how to post images on here. I just realized my photos didn't load. I will work on trying to figure out how to post an image to show you what I'm talking about.

It might not be you....
I can't post images today for some reason.
Been trying to figure it out all morning.
I can't even post an image of what displays when I try to add photos!
EDIT
I get a red banner that says
"Could not move file into" and then it lists a long homepage file path.
I am using an old iPad, but it has worked on this site for years with no issue.

Make sure you use the correct flywheel puller. Motion Pro 08-0026 is a good one.
Using a jaw puller often destroys the ignition.

Well then I guess I will stop trying to figure it out and prepare to watch college football.
(Pigskin ball. Not the round ball)
One of our Michigan teams will remain undefeated and the other will see it's first loss. Big time rivalry.

Or, you could watch England vs Australia in the T20 cricket World Cup - even bigger rivalry!
