No, the filter is clean. I cleaned it after that happened and i oil it VERY lightly and always have. And i've been doing it that way since i got it.
Benny...i may have said that when i first started posting. But if you read all my posts in both (maybe 3?) threads you'll see i have updated what i've said on a few things as i've investigated deeper. I've since found, and i think i mentioned it in this thread just withing a day or 3, that i can recreate it in a number of ways with clutch out, clutch in, or even in neutural. I posted this in this thread just yesterday....
"One thing i noticed thats VERY wierd. I can go down a hill so i can coast at a steady speed, the speed range the vibes happen at when the engine is engaged. Then either pull the clutch or put it in neutural and rev the engine and hold it at a steady 2k RPM's or so WHILE in neutural, i get the same cyclic vibration ! And this is with the engine disengaged. But the really wierd part is that if i do the same thing at over 25, it doesn't happen ! tell me that ain't bizarre ! The only thing i can figure is somehow at the rpm and speed the engine's cyclic vibe is there and tires/wheels are interacting harmonically when things line up just right to create it. Sounds freakin wierd but it does it none the less and i can't figure out any other way to explain it."
