Hi guys, I need advice. Excuse my spelling I'm from Czech Republic. I have a 2006 Buell XB12S. The bike rode great all year, but now I do not hold rpm. After a hot strart, decreasing rpm. Ecm spy shows me ets. The question is? Replace sensor, temperature rear cylinder? I have new spark plugs and cables. I have a Jardine exhaust and original air filter. I tried to rest tps and does not help me. Thanks
