He's not the only person with that problem using Amsoil. Here's another.
Something is causing the issue.
"Was curious because my Tmax is showing the same symptoms you had experienced, the RPM's going up higher than they should and the Tmax really slow taking off from a stop, and it gets worse as it warms up, I am also running Amsoil, 10W-40 motorcycle oil, I have since the first oil change. I checked my extended warranty and it does not cover the wet clutches, I have found on-line at Stadium Yamaha parts a clutch housing complete for $117.00, I think I am going to try and tackle this myself, nearly $1,000.00 for the dealer to repair it is too much for my pocket book right now. I bought the shop manual when I purchased my Tmax and it may have been a very wise purchase."
Then he said this later on:
"My Tmax is back on the road , the clutches must have been slipping for over a year, but the failure was so gradual I didn't notice until it became obvious, after getting it back togther and twisted the throttle for the first time with the new clutches I could not believe the difference, it was like going from an 50CC scoot to 1000CC sport bike, it takes off like a mad bumble bee from a light now. I had measured the old clutches using an micrometer and compared the reading to the manual, there is no sighn of wear, so it all must of have been from the Amsoil creating such a slick surface on the clutches that they would just slip, even though the clutches looked and measured fine. I had to make my own tools to get the clutch housing apart, no luck trying to find the tools using the tool numbers out of the manual, thank goodness for Harbor Freight for cheap tools I can modify to do this job. Amsoil is going to hear about this.
see you on the road, lets ride."
