[TECH] Measuring APEX SEALS (with pics)

The GSL-SE has such good oil injection that the seals will wear far beyond the limit of 7mm to th epoint where they break at around 5.5mm or so. If you can catch it before any of them break, there is a good chance the apex slots in the rotors will be in great shape. None of that slot widening you get with 12As and early carbed 13Bs with their inferior oil injection into the carb. By the time those hit 7mm, the apex slots are usually quite wide and require a new rotor or careful tapping of the tips back together, which is not a very good idea.

the slots on the rotors I took this apex off were in great shape. even the oil control o-ring carriers showed minimal wear
