I like them better than the adjustable ones.

Oh please, don't even post that bull **** acting like this is what the norm is. Tpost, the push rod that engine came out of is an evo on ****ing steroids with a slight dosage of satan. 89" stroker with a monster ****ing cam and tons of compression. Me and the owner of that bike that had the pushrod come apart like that aren't sure what happened, but it wasn't the pushrod that caused this. The plunger in the lifter actually undid it self and went sideways. Think of trying to stick a quarter right side up in a round hole. Bent the pushrod and blew out the tube. I have seen these broken parts in person and examined the lifter that failed. I think the pushrod slipped when the plunger flipped and went down into the lifter, and on the lift of the cam lobe it snapped the push rod and blew the tube. This was a LIFTER failure, not a push rod failure.

The point is that you're posting this passing it off as a pushrod failure when it's not. A stock pushrod probably would have bent and maybe even broken too. Not only that, the cams talked about here don't have nowhere near the lift or duration that the cam in that particular bike has. It's just not appropriate to post it like you did. If you didn't know, you didn't know. I don't know how much he informed you on what went wrong here.

All I knew was that the push-rod broke and came out the side of the tube.
That was the last I'd heard about it until tonight.
I still never said it was normal.

Ok then, well either way, it's not something that happens... like, ever. First time I've ever seen it.

I was hanging at the indy shop an an a bike was in that was down on power an it turns out a adjuster lock backed off an he just had to adjust it. I'd prefer solid stock ones but didn't want to pull anything else apart.

NP, just my theory though. The plunger definitely came un-done so it only makes sense... in my mind anyways.

Makes sense keeping the stock PRs, if you are taking the rocker boxes off. Because you are keeping your stock PRs, take extra time to ensure your o-rings are seated well for installation of PRs. It's always the top ones in the heads that could get pinched. If that happens, there are ways to fix without disassembly, but that's not going to happen to you right? LOL..
