This^^, without trading up the cams, results will be disappointing for the outlay. As a guide.. Jenveys are around £730, Airbox kit £599, ECU £715, adaptor £159, then there is fitting of the TBs, airbox and ECU and calibration of the ECU. Cams are £595, Verniers £268, then there is fitting of the cams and verniers and cam timing. it's a slippery slope. Oily
