So my Tomos runs a bit ragged and its throwing oil all over the chain and rear wheel.
When I get up to any decent speed 15+mph, I can feel and hear the engine sorta catching and releasing. It's really hard to describe. So it sounds like waaaaaaa waaaaaaaa waaaaaaaaa waaaaaaaaaaa... instead of
I can feel it too. So I'm riding along and I can literally feel and see my body jerking with the tension (thats a good way to describe it) on the engine/crank.
I replaced and rebuilt the transmission but didn't take the crank case off. I used to think it was in my rear axle b/c I had an interesting situation there as well but fixed that problem and still I get the "scrubbing" (another good way to describe the way it feels). I've pretty much narrowed this thing down to something going wrong with my crankshaft, seal or other related part(s). Any help in that regard is much appreciated.
The black oil on my chain and wheel is leading me to believe that that crank seal/bearing is shot, allowing the oil out and to fix that, I'm going to have to remove that crank case and somehow get the old seal out and a new one in. I don't have the special tools to pull out seals so I'm knowing that this will be a bitch.
I don't have any pictures up because I haven't taken it apart yet. (edited)
