my brute is knocking really bad i sounds like a rod is broke but im not sure it was over heating because i was low on oil hey it was leaking and didnt know there was a hole in the oil filter. wat could that knocking be? it dont make since for the rod to be broke or come lose it could be lose tho right?
If your engine is knocking the damage is all ready done and it needs to be rebuilt. A rod can't just come loose. Chances are if you ran it without oil, or very little oil for a long period of time you already did damage to the cylinder walls, rings, piston, and main bearings. I would pull the engine apart before you go any further riding it, just my two cents.

Ditto. Sorry man...they can't be run without oil. No engine can.

Sorry to hear about your engine bruteboy. I am betting on the crank bearings being shot. With any luck your cylinder walls are not scored and you may get by with a new crank, rods, and pistons. Only way to tell is to tear the engine down. Good luck.

I agree, probably spun the rod and/or main bearings. If you spun either one of those types of bearings, your crank is toast and, if the mains spun, your cases may be toast as well.
I speak from experience, as I've had my share of these issues while I was roadracing my '93 ZX-7.

if the walls are scored do i have to bore it or can i just put new sleeves in it? and how much would if run?thanks alot
Personally, I'd be more worried about the crank and cases than the cylinders. I think cylinders can be found (new & used) or reworked fairly easily, but the crank and cases can not be repaired if you spun bearings.

I did some searching and it appears that the cases are probably OK as Kawi uses roller/needle type bearing for the crank. Now, the one site I found that lists OEM parts, showed these prices:
$347 for each cylinder
$289 for a crankshaft
$715 for the crank case set (must be replaced as a set)
Plus all of the other required items to rebuild a Brute engine.
