Re: JTS 5000rpm engine noise!
I think its more than a heat shield its a louder deeper sound than i think that would be.
I noticed today that the air intake tube that feeds the resonator chamber was loose and all of the air would not have been entering the chamber.
I will be taking it for a spin later to see if that was the cause of the noise.
If its still there I might end up taking it to ALFA to sort it as I am running out of ideas of wht it could be.
