Hey guys,
I've bought a ktm 125 sx 06 from my friend a few months ago. There should be a new (one tank used) piston/con rod at the time when I bought it. Now there is 14hrs on the clock bought by me.
I checked the piston via exhaust port recently and I've seen some weird stuff so I managed to put the cyl down.
Here you can see how does it look inside.
Some object definitely made some **** inside the cyl, whatever it was...it did really bad job. I want to pinpoint that I'm really carrying about maintenance - cleaning filtrer after every ride...
Yes, there are little dings in the cyl's nikasil plating, but all of them seem to be pretty smooth, no sharp edges etc.
Please note that all the pictures are sharpened and it can cause that it looks worse than it really is, lol.
This is my first twostroke and my first engine which I've opened. I think I'm on a really high level manually, but I dont't have any experience with dirtbike engines.
Can you help me out how to solve this issue?
I know I will have to buy a piston and reeds, but what about cyl and head?
Bottom end seems to be ok, all bearings ok, no play anywhere.
Thanks is advance for your replies.
