Hi.
It seems as if the previous owner misused my XTX, since I bought it I monitored the oil consumption and it averages in the region of 1ml to 1km when traveling at around 120km/h. I did a compression test and got +-80psi instead of 85.3 - 99.6psi. Now I want to open the engine to see and measure everything, but thought of getting a OTR piston set while I am opening up. The OTR piston is a 11.5:1 compression ratio. In South Africa we have 93 & 95 octane fuel, what do you guys think, will I encounter ping? Any advice will be appreciated.
Thanks
