Did you install the Threaded Rod or someone else?

Looks to be SAE Fine thread in a Metric Hole, other than it has been over jacked probably why the thing is split.

Stock rod i haven't removed it at all. I have a feeling it is part of all the damage from the valve braking off and destroying everything including the connecting rod.

It's not all thread it's stock cylinder and head stud. Last summer my exzost valve broke and destroyed everything. It even bent the connecting rod. When i went to rebuild with 61mm bbk i found crack in block by head stud.20180708_073409-1.thumb.jpg.0e127a222a3b20180708_073856-1.thumb.jpg.a84fb360bd4b

So at a closer look where the crack is the ailment pin goes there. So i guess my question is what's my chances i could put it together and have it last.

Between you and me, I wouldn't trust it, I'm sure every time you rode it would be in the back of your mind, there's enough sheit happening out on the roads without having your bike grenade,  but that's just me.

That Grenade job is awesome!!!

It can be Welded if all else fails, 

Must get rid of the threaded rod and get proper Studs.

   Good luck...

I put it back together Thursday it ran good all day. I ride to work Friday on freeway the freeway is about 10 miles after about 5 miles the bike started acting like it was running out of gas. When i pulled over the fuel filter is full. Bike would start Wright back up and ride for about a mile and a Half and shut down again. I checked valve adjustment and it's good. Gas tank is full. I even put stock CDI and stock coil back. I was thinking i might have had wrong CDI and coil. I think the CDI was DC Not AC. Had same problem last year before value broke and destroyed everything. everything in motor is new. I put a new battery because the other one sat and wouldn't hold a charge. Any idea what it might be please help getting frustrated
