Hey just wondering does all lt250r's have a clicking sound in the motor? I have a 88 and the motor makes this sound and i cant figure it out i thought the lower rod bearing was making this noise so i bought a different bottom end and put my cylinder on this bottom end and i still has the same motor noise and cant figure it out every thing is sealed up good cause i did a leak down test on it. the guy i bought it from said the head had been milled so could that be the problem because i wouldnt think it is the rod cause both motors made the same sound. Just wondering if there is anything else that could be making this sound. PLEASE HELP!!
Sounds like someone dumped a few mexican jumping beans in your clutch cover.
Really though, elaborate on the clicking noise, when does it happen, how fast of a click, running or not running...

?
It's when its running and gets louder at idle.
Clicking or knocking?Is it random or the same in between tics?
Do you have anyway to take a video with sound that you can post up it would probably give someone a good idea.
I sure can but I have to work in the morning so ill try tomorrow thanks for the quick reply.
Piston slap?
Have you measured the clearance between piston and cylinder bore?
