I would say YES ..its been a few years since I did my lil comparison with a her cylinder which has never been stock ,has mild port work ..to improve bottom end etc (which was mine at the time ) ...but I do remember a difference & that a main jet change was more than obviosly needed ...it was alot leaner with the CR than trx which should indicate more air being pumped in etc..
now I only use the CR type set up on the big bores ..
remember port work, exhaust,carb,condition of rings,size of bore & filter are also other key factors here ,..so comparisons must be done with similar cylinder & carb set ups if possible or IMO are worhtless .. even better,.. ALL the same parts only switching the reed set ups
