I have a Peak Performance cylinder head from a 2004 Yamaha SXViper Mountain. It has three 19cc domes in it that are for 6000-10,000ft elevation and high-octane gas. This head has the ports for the DCS and temp sensors. It's in excellent condition and NOT from a blown engine. I pulled it last week from one of my sleds that still runs great, just want to get this sled back to pump gas. $150.00
