Hi I bought a complete cylinder head with HRC camshaft, the seller says that's came from a 07 bike ( MELG2 mine is MEL001), but there are same strange things that I found, first of all (as you can see in the photo) the cams are 180° reversed compared to the OEM , on the exhaust camshaft the cam position sensor is the same of the 05 model, in fact it's applied only 1 bolt. After assembling, and synchronized with the crankshaft I found that the engine rotation it's a bit too heavy compared with the original setup. Assuming the new head is 07 can I use the OEM camshafts of the 05?
