Honda RVF NC35 Help seriously needed

[andreasmkr]

Sounds like what happened to me. con rod bearing where wrong so the big end got screwed!
Sounded like one/more pistons where loose inside the cylinder

Wait, where was the oil level? Half way up the stick? Or halfway between the min/max lines? If it's halfway up the stick, then you have problems. Has the oil light been on?

It's pretty hard to diagnose the problem without even hearing it, but if the mechanics think it's a bearing or a conrod (they are different things), then you would be better off replacing the engine. It's cheaper, faster and easier.

its not at halfway of the stick. its like er.... at 1/4 but slightly higher than 1/4 but way lower than 1/2.. hmmm can understand? lol.
Nope oil light is not lighted up when on the move. only when stationary and bike is off, but ignition turns on.

I just went to another mech today. He, likewise told me the same stuff. have to open up and check. might be con rod burnt or the con rod bearing.

Is there anyway i can show you guys the sound? like is there a way to record or use any kind of instrument?

Mate..if it is making enough noise to worry you and it is becoming obvious that it could be and is likely to be the bottom end of the engine - conrod bearing on the crank (called big end bearings) then the motor is dead...

Sorry...

But its still ridable at low speed meanwhile right? im thinking of either selling it or repairing it..

I wouldn't ride it at all. I'd be waiting for a new engine and fitting that.
