i sold mine with almost 120,000kms with quite a few mods on and off and never had any problems with the engine and it did get quite a reving. I remember doing the custom intake few years ago and the sound just made me wanna rev it more
Still returned less than 5l/100km on the highway and oil was still almost like new at 10,000kms(washed my filter every 3000-5000kms
