Scott, if there was no recent maintenance that could have caused a problem, I am wondering if a rodent nested inside the airbox, and the bike is starved for air.

Beautiful bike. That red is spectacular.

What is the purple tag by the left passenger foot peg?

 

I wonder if the air box flapper isn't operating correctly

Ok so the air box is fine but whatever the knocking noise is its whats causing the problem just tried to ride it and cant its like the whole thing locks up and just dies and when you get moving its fighting you and the exhaust smells like raw fuel like the fuel cant burn properly cause its fighting its self to keep running and when its in neutral and rev it a bit it cuts out and dies

 

just checked the oil and its full of fuel could this be my problem the oil level glass is way past full pulled the oil cap off and it stinks of fuel thats why when i start it it smells like raw fuel from the exhausts

 

Sounds nasty mate, I'm no mechanic, I'd be taking it straight to the shop.

The fuel is washing all the oil off of the cylinder walls, thus the engine should not be turned on again. Have it towed.

You should send some oil off for an oil analysis. An analysis of the metal in the oil will tell if any wear was done, and which specific components were worn. If the wear is bad, you may make different decisions regarding the repairs. I do not want to scare you, but there is the possibility that major wear occurred. You need to find this out before you begin to pay for repair labor for the known issues.

 

Hopefully you didn't spin a bearing

Are you the same guy that has been talking about a fuel injector being stuck open?

 

thank you for all your help guys i appreciate it i found the problem and solved it the knocking noise was coming from the head so i dropped the oil and it was full of fuel 5 and a half liters come out of the engine and 3 and a quarter was oil the rest was fuel someone tried to steal the bike and noticed it had a disc brake lock on it and the bike is nearly 300kgs so it wasnt moving lol so they filled the crank case with fuel nasty buggers i put fresh oil in and ran it on center stand for 20 mins and then dropped the oil again and topped it up again and the knock is gone its idling fine now and the POWER is back lol the BEAST i awake again haha so i truely thank you for all your advice and support :smile-new:

 

Why would a thief spend money on gas just out of spite/frustration?

 

To me, why would someone be a thief? There is no reasonable explanation for the things some people do.

This is a crazy story!

 

Uhh...for financial gain.
And there is none in vandalism (even less so in giving away gasoline, while risking being caught), which is why I don't think it was a would-be thief. More likely a disgruntled neighbor, or a problem with the bike itself.

 

What happened to The_Kow who started this thread?

 

Most thieves will live a much poorer life than working a steady legitimate job. Even putting all cash aside, how many camcorders does one have to resell in order to provide the most basic employer-matched healthcare? So overall thievery is a loss, not a gain.
