Wow. "Plenty of others who have spent a lot more time and know as much or more... most of them are long gone.." Really? Seriously? And how would that help the OP? Oh wait, it doesn't.
He was looking for people with experience porting heads. Damon has done a ton of work, gone down the road he is going and has investigated most if not all of the engine options and mods when it comes to the RC. Oh wait- he actively races his RC at the club level. Hmmmm someone in the same shoes as the OP. I'm not saying Damon is a god, I'm saying he is a still-active member in this community who could shed major light on his question. My best friend races with him, speaks very highly of him, and when he says someone is a good dude (like he does Damon), I believe him, no questions asked.
(I've never really responded to your comments, but alas, I can no longer refrain)
And it's not all good. Your response is as usual, full of ignorance, assumption and completely baseless. Your first mistake is assuming I have no experience. Your second mistake is thinking I'm new to this world. I'd justify my internet cred, but that would require resurrecting the Motorush database, which can't happen, tracking down my old bikes, um, no, and oh yeah, I'm not 10 years old. The fact you are surprised by my response says nothing of my response itself. It says everything about you. Very credible members, racers and vendors alike (old and "new school"-fwiw) have voiced their opinions about you in the past. I've tried to take them all with a grain of salt and have refrained from passing judgment. But how does the saying go? Oh yes, "It is better to remain silent and be thought a fool, than to open your mouth and remove all doubt."
There are those who think you are the king of carbon and your pipes are the greatest thing since beans and franks. I don't have an opinion of your carbon, your pipes, or your peddling of Chinese knock offs. But based on your internet prowess I think you're a hapless retard with no social skills and couldn't talk your way into a paper bag, let alone out of it. I don't even think you ride. You might own an RC, but it is probably kept in your garage for your "Development," "Engineering" and "QC." Undoubtedly you don't, can't, or hardly ever ride. Go back to concentrating your cannabis, lobbying congress for unemployment benefit extensions, or whatever it is you do. Based on what I've seen on this site alone, I can't believe a mod hasn't banned you. My suggestion was and is more than you've ever contributed. Take your vagina wagging carnival ride exhibition elsewhere (I apologize to the proper vagina equipped populous).
I apologize only to OP for this post (I had an A+ sales transaction with him) and I reiterate my previous post. Talk to Damon. I've read his threads. Independent of this forum, I've been told he's a good dude and has a wealth of knowledge at his disposal.
Carry on.
