Thanks, wirespokes.
I'll keep his number! Â
Today a (3) friends came by to help me with the project. Â We drilled through the existing holes on the flange and on the head. One friend, Niel, a retired engineer used two aluminum aircraft rivets to secure the flange. Â Nick, my other friend who just rebuilt my Honda 125 SL engine gave his blessings on what Niel had in mind. Â Randy, my neighbor and friend helped with a thread file to file down the rivet on the underside of the exhaust flange. Â Once the rivets were attached (not with a rivet gun but tapped in and flared with a special ball peen hammer, everyone was satisfied that the flange isn't coming off so fast.
Meanwhile, I consulted Bruce in Australia and Rob Valdez about a nice head on Ebay off an '83 R65LS that only had 15k miles. Â I bought it for about $107 and plan to get it cleaned up. Â I also offered him a price for the left head (of the same engine with 15k) so I may end up with a spare left & right head, just for good measure.
Right now, the bike runs awesome. Â Going to take short trips until I build my confidence about the integrity of all components. Â She's got a mean growl with that Lufmeister pipe.
I'll post pictures later - going to take a siesta - been quite an emotional ordeal but happy to say All is Well with the Red Hen!
