Has anybody had any issues with United 100 petrol?
Saw an item on MA site and got hold of some, mixed at 30-1 semi syn oil and 5 laps of DT the yz400d nipped up
.
A strip down discovered a peice missing from the top of the piston at the exhaust and seiure marksp at piston sides.
I have since heard a few negative comments but some good ones.
Or is it not compatable with 2 stroke oil?
