Howdy y'all.
I was on my way to my mechanic yesterday for some maintenance work. About 1/2mi away from it, I came to a traffic light on red. Immediately after coming to a complete stop, I was engulfed in white smoke. The oil was leaking badly so I pulled into a gas station. Not knowing what might have gone or still is bad, I rode the rest of the way (after cleaning the lake of oil at gas station and apologizing for the mess, of course).

Then, the mechanic had found --- not only the front sprocket nut missing, but so is the threaded portion of counterpart (same as the case below) which seem to be Drive Shaft. How common is this? I was spending hours on local twisties the day before; I came pretty close from killing myself out there. I see on different forums about this nut coming loose. I had it checked not long ago, but I honestly cannot remember how long ago.

The mechanic had told me that the complete overhaul would cost give or take $2000 with new parts (gaskets, seals, bearings and all that). I may be able to save a few hundred$ by reusing parts where I could.

I love my DRZ400SM but I was contemplating to get plated 450s. I would like to get some opinions as to what my choices I may have, and what former/current/(future?) DRZ owners might do in a scenario like this... Repair/Rebuild? Engine Swap? Sell as is and get another? I'm little inclined to just repair, at least I know the history of the bike a bit more, I'm pretty happy with the rest of the set up on the bike and with the mechanic... but what do I know... I maybe missing some factor from the equation... Any thoughts? tips? advises? Thanks for your time!

Crash279, phrolic, thanks for taking time in replying.

I did a bit more research and stumbled across this thread.

Someone had the engine work done at Yoshimura RD, up in Chino, CA.

I happen to know someone there, so I'll see if I can get a decent price.
I should also check Eddie Sisnero's place too...

Tapping into the broken shaft!? woa, that's pretty wild for me. I envy the ones who were successful at it...

Thanks again!
