2007 Tourist 750

Driven like a dream for the last few months. No mechanical issues at all.

On my way home I hear a light knock in the engine.
Knock gets bad about 1/2 mile later. I pull over in time for my bike to die.

I take a look at the engine and my oil pan plug had gotten loose somehow and looks like it pretty much emptied my oil.

I let it cool down and put some oil in. Starts back up knock goes away and theres a very loud high pitch whine.

I run it for about 30 seconds, put it in gear and it dies.

Right now engine turns over strong. no ignition of any kind. Don't know where to begin my journey into making this better.

Please help.

My guess is you will have to go through the entire engine to determine all the damage. Probably bearings as a minimum and possibly a crankshaft and maybe a top end will be involved. It will probably be expensive.

Bummer, sorry,

Rebuild, or new engine.

I continue to monitor the snugness of the bolts on my rig, per the cogent advice to do so as mentioned on this forum. Since taking delivery, every bolt has been and remains properly tight...but for a few of the allen heads on the oil pan (sump). Several were observed to be barely snug, at varying times. I used (and recommend) surface-insensitive blue threadlocker for those particular bolts.

I also monitor the engine oil level pretty religiously. This includes checking it in the field, so to speak, when the rig has been parked for at least 15 minutes.

Getting it running.
Record compressions
If knocking continue, pull cylinders look at rings and wrist pins, check for play.
Check rod arms for in and out moments.
More likely you need rebuild top ends.
If no noise after restarting just run the pi$$ out of it.

If lost all its oil, then toast. Similar happened to a guy in England, (oil pump drive gear cap unscrewed and fell off) dealer did complete rebuild, don't know what it cost.

Quick update

It's turning over.
Engine bits are still moving
There's compression so i'm starting to think it's not the end of the world
Spark plugs aren't sparking. Going to replace with new ones and see if it does anything over the weekend.
