Hello Gents,
Just a little update... The MOCO decided to void my powertrain warranty leaving me and my dealership stuck with the sumping issues and repairs. My warranty was voided because while the dealer was replacing the "upgraded" oil pump a TTS Mastertuner was installed. The regional tech never even showed.
My dealership went through my entire engine, found heat damage, and did a rebuild. At the time, this scooter had 800 miles on it... Sumping since day one.
At the same time MOCO eventually sent the new cam plate. Good news is... It does help. It DID NOT fix my sumping issues completely.
I live in central Florida and took my scooter on an Iron Butt Run. I left here and rode up to "The Dragon". I did 1175 miles that trip. It sumped minorly in comparison to how it used to. I would just stop and let it idle (standing straight up)until it was back to normal.
When I came back I took it to the shop again. Still believing it is a crank case pressure problem, they starting investing the venting. Where the breather lines come up to the back of the air cleaner... They noticed that the bolts used for venting (holding the air cleaner on with holes through them) were not providing adequate flow. They drilled them out. More like the size on the old 110s. This combined with running a little less oil has helped as well.
It still gives symptoms of sumping if I run it really hard, but everything that has been done has helped. At it's worst now... It may have a 15% to 20% loss in power for a very short time and corrects itself while riding.
Since I now own my powertrain (Thanks MOCO) I plan to do a 124 kit and the S&S pump setup soon.
