Any issues with clutch slippage on full synthetic. Two dealers are telling me that they only put the 10W30 full synthetic in their motocross bike, but not the road bikes. They both encouraged me to use semi-synthetic oil. Of course you have to go to a different brand than Honda for that. Might just go back to regular Honda 10W30 and see if it gets back to normal as it was before the 600 miles service when the dealer put in the 10W40...
