Hi there hoping someone can help me out.
My sons kx 85 2015 is making a tapping noise at idle as soon as you open the throttle a bit above it stops?
It has just had a full rebuild bottom and top ends main bearings and seals all genuine parts.
I sent the barrel away and had it recoated as well it had a small mark on the bore.
We thought the noise might of been the power valves in the bore so i have replaced them as well but its still making the noise not dure what do next any ideas would be a great help.
Cheers.

And it has a forged piston.
The Shop
But i have heard that.
Thanks mate.
Thanks.
Sounds like the piston is kissing the head, but just barley?
Remove the head and see if there is a small mark where it's touching the piston.
Thanks.
Thanks.
Or, could be panametric fam.
Re checked the head and jug pot bolts and all tight.
As i ve said i re placed the 2 valves in the pot and new shaft only thingi havent replaced is the kips shaft.
The intake side has been ported so im not sure if that has something to do with the noise but i wouldn't think so.
Thanks.
Cheers.
Hmm, well it does sound perplexing. It still sounds like something is loose (or compromised/cracked) as the sound goes away at a smoother operating rpm (harmonious balance). If you've checked the motor mounts at the swingarm and base and they check out, then maybe it is the pv. When components are cool, start it and feel areas for vibration. Try stabilizing with your hand and see if you can "make" the sound go away. Trouble shoot different parts, etc. Im curious what it is.
Thanks heaps mate.
