A few things come to mind. How would I have known that you were supplying Randy's cylinders? The fact of the matter is, I didn't. Further more, it doesn't matter. I'm not attacking a you, Randy, or anyone else. I'm attacking a very poor product. So, we can leave the names of individuals and companies out of this.
Further more, there has been no communication to suggest that these particular kits have been improved. I provided feedback, and have heard nothing since then. Randy showed one good 372 kit. Jeremy shared another 460 kit that was nearly as bad as mine. Again, the inconsistency in quality.
Additionally, you're implying that because Randy got a decent kit, that they're all good and should be trusted. Quite the opposite has been the case with most of these AM kits. The quality control simply isn't there. Inconsistency is one of the main reasons that I simply won't deal with them for a paying customer. One cylinder will be fine, the next one junk. Do you think someone wants to pay $250 for a port job on a cylinder that is that inferior? IMHO, they're wasting their money, and I'm hurting my reputation. It's not profitable or wise for either party.
You mention that you have seen bad OEM cylinders as well. Bad is a very subjective term. I can guarantee you, that I have never seen a cylinder come from the factory any where near as bad as these kits that I shared. Also, OEM quality is much more consistent. To suggest otherwise is simply not being honest.
You related this to comparing my current work to my earliest work. The difference, is that I have shown the improvement as time went on. IMHO, the burden of responsibility is on the provider of said cylinders. If they've been that significantly improved, at a high level of consistency, then that needs to be shown. That's what I'm asking you, or anyone else, to do here. Referencing one cylinder does not do that. How many bad AM cylinders have we heard about, while at the same time, there are others running them fine. Again, you can't trust the quality.
I want to add, that I highly respect the fact that Randy will not sell these kits as they come from the factory. That is consistent with the Randy that I know, that wouldn't put his name on junk. But, when I see them being pushed without said mods, then I feel that I hae a responsibility to share what I've seen with the rest of the community.
It would appear that you're asking me to buy one of your kits. Why would I want to do that? I'm not selling them and I'm not interested in them until I see a consistent huge improvement in quality. Again, that burden of responsibility is on the provider of said kits. And remember, I'm not attacking you as a person, I'm simply pointing out the problems that I see with these kits, as a service to this community of users that otherwise might not be aware of the risks. If you would like me to review a few new kits, I'd be more than happy to do so, and send them back afterwards. As always, I'll provide honest and transparent feedback, just like I have here. My goal here is not just to warn unsuspecting buyers, but ultimately, to see these products improve. I've given feedback and suggestions on these kits over the years, in an effort to help make that happen. I'd be more than happy to do that for you as well.
