Genuine Yamaha inlet and exhaust camshafts. Used but in excellent condition with lobe and base circle measurements all well within specification as you can see in the photos. These camshafts are for earlier models and have slightly different valve timing than the 3H5 camshafts used on later models. Generally I would say that 78 and 79 models use these 2H7 camshafts and 80 and 81 models use 3H5 camshafts, however please check the parts book for your model or check with me if you are not sure. The photos show all of the lobes of these camshafts. There are lots of pairs of camshafts to buy here as you can see, but these are the only ones where you can compare actual measurements to specifications and wear limits. Price is for the pair. UK seller. Please note that free post to UK addresses and the reasonable charge that I make for international post will not include tracking.
