Todays machining took 4 hours taking it very slowly. We had to machine 0.90mm out of the casing so the barrel could fit into the crank cases with the correct air gap. The material used for the casings on these motor is very poor quality.
To make sure all was well after machining the casings, I pulled off the clutch cover to check the wall thickness between the clutch side & the crank case 4.35mm left after machining. I did a fluid test on the clutch casing to see if any fluid leaked into the crank case, I did this because of the poor material used by Yamaha & was worried about oil pressure on the clutch side.
