I clean the plugs every-other time out. Actually, i'm still running the original plugs!!! Yes, definitely designed to run rich and that's fine considering the condensed heat. Always notice a big increase in power when riding in spring fed waters (less than 70 degrees).

Pulled mine for the past 4 years with both my RSX-S and the 99 CRV. RSX is actually better considering the braking. I actually took it with me to the 12hrs of Sebring 3 years ago!! lol. Not sure about towing with the S. It sounds good ... but I'm a little cautious.
