My piston from my 86 r cylinder

[pantera1975]

This is a 66mm piston from my 86 R. I put on a honest 2000 miles which is about 80 gallons of gas half the time mixed 40-1 and the other half 32-1 and ran a fmf pipe during them miles. Had low comp 145 psi and alot of piston slap. I bought this thing in april of 2010 from the original owner. It did have a fiber head gasket in it but not sure if the piston or rings have ever been replaced. I was shocked at the condition of the pison and the cylinder. The previous owner said he always ran klots for a long time and I ran R-50 too.

this is what happen when you run a good oil and the right mixture of gas an oil.

Wait, wait, wait. I thought 2-strokes have to be rebuilt every 5 hours? /sarcasm
