I bought a CF500-C brand new in 2015. At the beginning of last fall, I began experiencing some problem with the engine overheating and going irregular when on idle. The dealer's mechanic said he had solved the problem but in no time, the trouble was back.
This week-end, I invited a good friend of mine, an experienced mechanic who finally found whath was the problem.
Wires from the dyno burned deep, melting the envelope. False electrical signals sent through the whole machine disturbed the injector.
Will I have some chance to benefit of the warranty, since I opened the engine myself. I will see and report.
