Just installed my Miller Yuma 2, bought them second hand witch were 60miles used.
Is it necessary to fine tune the engine at my dealer?

Generally not necessary unless you are changing to a low restriction intake. The intake will cause an already lean mixture to go even leaner which would require a reflash or some other form of remapping the fuel control module.

Thanx. Rode a 60 miles trip this afternoon and the bike did nothing unusual, performed better than before. The temperature was the same as usual and the sound is nice but not too loud.
