Harley Evo Engine HAND GRENADE!!

[@harleyriderny69]

What a mess..great video.👍😎

[@sfcustomcycles]

You're not wrong legend! Assemble video coming up

[@rustyruss9485]

That looks like a rebuild from when I was a kid! Almost 70 now, started with basket cases about 14, didn't make one actually run until 16/17 years old. Some great times being a kid, no knowledge just best guess, borrowed tools, gaskets made from cereal boxes, parts from wherever. 🤣 Thanks for the flash back.

[@sfcustomcycles]

I appreciate this! Do you still have bikes now Rusty?

[@doughurt2979]

84-93 that's how Harley installed the studs because the cases were milled thin enough that torquing with lip facing down would sometimes crack the case's.

[@sfcustomcycles]

84-91 are renown for cracking at the oil journal feed right above the cam chest - You cant comp those early engines up to much either, 92-99 are good to go!

[@breakawaymotorsports]

I call those rebuilds "keggers"..as in how many kegs of beer were consumed during assembly.

[@sfcustomcycles]

🤣🤣🤣

[@Lanesplitter]

Prior to '94 the studs were fitted that way from the factory - also they used a softer head bolt which would stretch somewhat, look for CP forged into the head of the bolt, and swap them for for the later part number revisions.

[@ClovisPoint]

so thats why the gaskets leaked ...........................

CROIKEY!!!

The question I often ask is, "So when did you learn the value of a good mechanic?"

[@smiley4288]

Wow 😮 just wow 😮 😮😮😮😮

[@sfcustomcycles]

Tell me about it bud!

[@itsmytimeletsgo]

Often so many problem created by bad mechanics. Its the little things that make the differences in the long run.

[@sfcustomcycles]

I couldn’t agree more!

[@MoreCycles]

What's your thoughts on the S&S reed valve breather?

[@sfcustomcycles]

Definitely the way to go - Ultima offer a breather also at a fraction of the cost of S&S

[@inhocsigno9151]

Scary.

[@sfcustomcycles]

Bit going on here man!

[@nairbyad7188]

this is why no one works on my motos

[@sfcustomcycles]

Rough i know, it's a shame bud

[@swamppifi6186]

how can you put studs in up side down.....

[@sfcustomcycles]

If only i knew who built the damn thing 🤐

[@MoreCycles]

Ask Harley, they used to install them that direction in the early motors. 😂

[@sfcustomcycles]

@@MoreCycles exactly, hard for when you want to deck cylinders & heads too

@@sfcustomcycles Great video, everyone needs to know that morons name..... I hate seeing people put their trust and cash into some idiots hands.... wish they would ha e found you first. Keep up the awesome craftsmanship !

[@JohnMcClain-p9t]

Somebody should never be allowed inside motors again! I was turning wrenches as shovels went out and evo's came in, that issue with the cylinder studs was a factory error back in the nineties, when Harley was having all kinds of problems with such studs. I can't believe someone who "knew what they were doing" assembled that crank, probably the worst I've seen, rollers fitted too tight, no excuse for that at all.

[@sfcustomcycles]

I bet you’ve seen it all bud! That crank has its own story! If only you could feel how sharp lipped the brass shims were, very very bad. I’ll do an assembly video very soon 🤙🏼
