Does anyone have any info on how to clean the Apv power valves?I Have about 1500miles on my Zr900 and it isn't performing like it used to,Im thinking they might need a cleaning.Any info would be great.
Just asking. I run Amsoil and before the season started, I cleaned the valves after sitting all summer and they pulled right out -- hardly anything on them. That was with around 1700 miles on from last season.
I put close to 4000 miles on this season and haven't had them out yet. I haven't noticed any loss in performance or fuel economy, so I assume they shouldn't be too bad. I plan on cleaning them in the next couple weeks.
