As fast as USPS has been lately, I'm sure they order direct from Japan, ship via ground.

Actually, I do like USPS. First class on all my CDs is usually no more than 3 days delivery US.
As for BikeBandit, my last order arrived Priority in 3 days. Ron Ayers can take as long as 9 days...they order from Japan, I think
Motorcycle Superstore is also fast but they don't do OEM parts

Well, this will be a first. I don't remember anyone actually witnessing a blown head gasket. How old is the bike?

So...what causes the head gasket to blow ?
1) I thought it was a loose head, in other words, bolts not torqued enough..........
2) Or, improper assembly, which could be related to #1 above. But, having done a head myself, the gasket part of the rebuild is rather simple so this one would be minor reason.
The used head I bought at the local salvage yard came from a bike that the guy said the bolts were just over a "finger tight" torque.
Makes you wonder if that is why the bike was in the yard (blown head?), and also makes you wonder how many dealers "total" a bike for a blown head. Note: I think the Dealer labor charges make the idea of totalling an "easy fix" a reality on the older Savages.

"Why?" is the next logical question, for sure.

the speedo on the bike says less than 1500 miles... but no telling if its the original tank and speedo.. i can tell its been repainted.
not sure why it blew but noticed a few signs of a small leak .. small puffs of smoke coming out near where the exhuast and head meet.
warming it up one day and it made a big puff and then died. wont start anymore.
im excited to start riding again.

WELL, of course, the first and easiest way to check for a blown gasket would be a compression check, ya know.
Just have to remember to disable the decompression solenoid...

The guy at the salvage yard said on the LS650 you got to make sure you're getting oil to the head after re-assembly before riding. He said to loosen the one head cover bolt that passes thru the oil passage. Crank and make sure you get oil out.
So....here's a funny.
When I put the engine back together, I kept the bolt loose like I was told to do. Took the spark plug out so there was no compression (no load) on the engine and then cranked it over for the first time. I watch for oil coming out of the bolt..... nothing......crank again ...... nothing. I thought., D..mn, I must have got sealant in the oil passages. So, one more try, this time with the bolt all the way out. Crank crank........ splash....oil all over my face & safety glasses
. Slipped the bolt back in loosely and cranked and oil again......Yea....

That's actually a very good point. Some bikes have a bleeder for doing that, but while your cranking it, what's lubing the cam shaft? A good idea is to use an assembly grease on the top end parts, so there is lube before the oil gets up there.
Note to self: Don't look in spark plug OR bolt hole when cranking engine

Wuhhh? I thought the decomp dropped out after something like 2 seconds, just long enough of decomp to let the starter get everything swinging good. Is this not so?

That's right, the decompression solenoid is de-energized 0.7 seconds after the startbutton is pushed in.( source the SSM)

Yeah, but you can't use it if you are doing a compression check.
