I called up George from Uptite since he seems like a pretty knowledgeable person brought up on every husky forum,He told me that that "ear" being broken won't be an issue as it doesn't cause enough pressure to cause damage, he thinks it's likely the drive nut came loose and mangled my oil pump housing screws/bracket. He also told me to look through the oil sump for that piece that broke off so it's not sitting in the engine, so I ordered one of those little telescopic magnets to see if I can snag it.In terms of repairs I came up with a rough budget for different options...There's a crankshaft on ebay for ~280 that is the same part numberEngine gasket kit w/ crush washers -> 149.99Engine seal kit -> 105Main bearings -> 35*2Timing Chain -> 73Aftermarket Piston -> 190800072425 (Cover replacement for the one that got mangled) -> 7.25800067997 (screws that got mangled) -> 0.25*2Dan from MotoXotica quoted me those numbers and said that generally when folks rebuild an SM610 that's what they get.He also suggested redoing the valves which would beintake valves -> 49.99 * 2exhaust valves -> 79.99 * 2So if I am going the route of replacing parts:So it would come to ~ $1128 with new crankshaft, valves, etc.Or I could skip the valves & it would be ~868Or I could skip the new crankshaft & it would run me ~588I talked to a crankshaft repair machine shop & they told me if I bring in the crank on it's own it would run me around $90 to repair the crankshaft ear... But they said that cast iron is very brittle when welded so he doesn't know how reliable of a fix it would be.I think my main question for you guys would be... what would you do? Would you invest another theoretical $1130 into the bike to get it running again w/ fresh new engine components? Would you just part it out & cut your loss?I have the crankcase splitter & crank puller if I need to split the cases & reassemble.Open to any suggestions
