maate..be very careful starting it if your not sure of the case seals condition. if they let go you could have a runaway engine so ensure the kill switch works... the seals are known to fail (ol mate did 3 top ends before he realised the seals were letting in air under heavy load) you can pressure test the motor, search on here so you can get some confidence. i recommend replacing the flywheel side (can be done from outside) and if the gbox side dies, the smoke trail is a good indication... 82.5 is std according to the tech specs sheet ive got.
thanks for the info. ive ridden this many times. no runaways. no excess smoke. kill switch works.
i believe compression was much higher than 160 psi though. ill re-check when the head is back on. gasket arrives friday.
i was planning to try some aviation fuel: 100 octane low lead. a mate says i should upjet for that since its oxygenated. i may just mix a gallon of it with some 93 and see if i notice a difference.
