In the midst of doing an 77 Rm125 FMF racer replica and gathering pieces. I found/bought this porcupine head that was claimed to be NOS and never mounted. That part may be true,however, as many porky heads as Ive seen, Ive never run across a gold one. Ive called and emailed FMF trying to get ahold of Sr or Lil D, but nobody has gotten back to me as of yet. Do any of you guys know for fact that they may have produced some gold ones ? Anodizing on cast aluminum always comes out blotchy and usually looks like ass,and this one is no exception. But, before I blast off the gold and bring it back to bare aluminum ,Id like to know if this an actual rare piece . Any one know ??
Looking closely at your picture it looks like there are pit marks in the dome. Pitting is normally due to a fragged piston ring.
dinged up head. But after looking very ,very closely ,we've determined those are from the porosity in the casting.You can actually see some of the same marks on the gasket surface. But ,its not important to me thats its NOS or not,since this bike is going to be ridden and raced,just Im perplexed on the anodizing. So most likely its destined to be put thru some bead-blasting, unless someone pipes up that Big D had made a limited run of these gold ones.
Did you try MXA? I normally am not a fan, but they would have the knowledge base from that era.
