I had the same configuration of a Bullet cam and Morel (branded as Bullet) lifters.
What happened to me was one of the link bars came loose when one of the rivets popped off of the lifter pair.
That allowed the roller lifter to rotate in the lifter bore, which wore both the cam lobe and the lifter roller.
Once mine started wearing, it wore very fast, in about 200 miles. Post-disassembly, appeared to be just the failure of the lifter pair (the rivet), but not an engine build issue.
Doug - I think you’re being a little harsh on people who choose different solutions?
If you recall – not that long ago, everybody was talking about how catastrophically solid lifters fail because of a lack of ZzZz ZzZzP.
You pays your money and you takes your chances. Everybody puts a lot of thought into these motors when you’re spending 10 grand or more to build one. It’s easy in retrospect look back and say “oh you shouldn’t have done that”.
And like you said, lots of people have built this configuration motors and they have run well.
Anyway – good luck with the fix Rene. I suspect you’re going to want to disassemble your engine and flush it out. I like the Bullet Cams spec, but I went with a different roller lifter manufacturer on the repair.

With two clearly documented failures of the same part, people may consider not sourcing their roller lifters from Bullet, if that’s the path they choose!
