Piston

[Parney]

I bought a kdx 220 quiet clean inside my piston has A top I take it this is standard

That looks like the stock piston.

Did the previous owner mention head work? Does a stock head look that good??

Totally standard wiseco piston arriving tomorrow bike only done 4000 miles I put motul 5100 in gearbox 10/40 the clutch slipped really bad

Did you clean the piston top while it was still attached? Sounds risky.

Measuring the piston diameter before ordering another piston would have been a good thing, just in case.

Which 10w-40 did you use?

I am a big fan of putting motorcycle oil in motorcycles.

If gearbox oil has friction modifiers, this may cause clutch slippage. Many on this forum use ordinary Type F ATF with good results.

I put this in it foooooked the clutch

That should be fine, it's rated for wet clutch. I would check your clutch spring free length and the disc thicknesses.

Yep, that should have worked just fine. Like was mentioned, measure everything to see if all is in spec.
