From here...that actually looks useable to me. May well be a lil alloy still left on the cyl wall. But clean that off, and away you go with a fresh piston and rings I'd say. I'm thinking the compression was down as the rings were stuck in the groove?

i agree, but hard to make a call off picutes,

take it out to Mr Motorcycles in Pukekohe, no one has done more work on kx85's than us

talk to Steve the workshop manager, or one of the senior workshop guys and they will tell you straight,

hit it with some sandpaper. it won't touch the nikasil - it's way too hard.

it should come up quite nice with some time spent on it. i've seen this done successfully a few times.



everyone is way too paranoid about nikasil coatings!

i wouldnt do this to my race bike but if it was old and for the mrs i wouldnt think twice!

I did something similar to my kx100 and took it to engine specialties in Wairau, they diamond honed it for $35 and sent me on my merry way, I put a new piston and rings in and it ran a-ok for the rest of the time I had it.

I ended up getting the cylinder honed at Mr Motorcycles, it came back like new and ive just finished installing the piston etc. It fired up and ran great.

Thanks for your help!

just as a note, we use a very light hone to clean up these cylinders as not to damage the coating, glad we could help
