I've had my Recluse clutch for a while now and just can't seem to come up with an engine oil that gives me the best clutch performance. I've been using Spectro oils in my bikes for a few years but had to much "slip" when the Rekluse was installed. As per company advice, I went with the additional carbide balls. At that time i changed to the suggested Chevron Delo series oil. The clutch worked great but the oil seemed to break down pretty quick. I was worried that the Chevron oil just wasn't up to the needs of a modern four stroke. I started using the Yamalube4 but I'm still not convinced I've found the right oil. What are the rest of you Rekluse owners using?
