Just replaced the piston rings at 54.2 hours on my 300 perfectly straight forward really
The barrel is in excellent condition and the piston has no scoring but has signs of the Teflon dissipating
I ran some scotchbrite through the barrel for about 10 seconds and put it all back together I primed her with the kicker before pressing the button and she fired into life
Happy happy happy

I was bored shitless, it was pissing down outside, id previously said I’d do it at 80 hours and just to minimise the endless retarded comments about the machine being a polished turd

I was going to ask you to load me pictures stu
And dek yes I put a little exol on top of the piston she’s running sweet

You just undo the bolts and remove them just go steady it’s pure common sense and should take you a couple of hours tops

This is true but I’d thought I’d have a peek and clean

I use exol and it looked pretty good so just left it as is

Used Exol in my TPI and it jammed the rings, the same container of oil was given to me by a mate and did exactly the same to his bike. I think it must have been a dodgy gallon as used it before with no issues, but now I don't trust it if one crap gallon can slip through the net

I've used Exol since 2015 .... 16 17 19 bikes.... no problems ...as advice from the late great Ross Hall
