Hello All,
I don't get a chance to post much because I find that the answers to my questions can usually be found in this great forum already. And for that, all of us "newbies" thank the experienced veterans for their advice and support. So here goes for a potential issue I found yesterday:
I am at the "go cart" stage for my MkIV build. I have a BPE 302 with Sniper EFI, and the install could not have gone better. I mean, everything went so smoothly! I have been taking my time to try to pay attention to every detail that could be a snag. When I connected the battery, nothing went poof. When I primed the oil system, a mechanical oil pressure gauge showed 50psi! When I put the fuse back in for Sniper power and plugged in the fuel pump, I had 58psi and no leaks! Wow!
So for my son's 16th birthday yesterday, I let him turn the key for first start. She turned over a few revolutions and fired right up! No sputter, no hesitation, just straight to idle. I wish I had watched his face, but I was too busy looking for spewing fluids. And there were none! Too good to be true!! And it sounded so good...
Which brings me (finally) to what I'm hoping is normal, but has me a bit worried. We let her warm up to around 160, all the while I'm walking around looking for leaks, watching gauges, and making sure nobody gets too close to the sidepipes. When the electric fan kicked on, I figured we had enough wins for the day and shut her down. Still no leaks. Awesome.
That's when I noticed the headers. They were no longer the pretty chrome headers that FFR sent me. Now they are a blend of blue to bronze color, and even the sidepipes are a little gold toned after cooling back down. Is this discoloration normal? I know that some is normal, but is my level of discoloration to be expected? I'm hoping that someone (or many) will tell me that I haven't done anything wrong and no permanent damage has been done to the engine, and that maybe my A/F mixture or ignition timing just needs to be fine tuned.

I'd love to hear thoughts and input!
Jason
