Haven't done nothin for a while, but I ordered some hyper ss mudgaurds. And fitted them to the EB4. Pointless I know, just wanted to add some feature to the body work. Shell is on its way out.
Yeah new bell, as George says. So maybe the mesh was too tight, causing your clutch bell too disintegrate and eventually lock up the bell and spur. Whenever I take my engine out I take it out from the top so I don't have to re-mesh every time.
I think your engine mount screws from the bottom of your chassis have come loose. It was worth checking your clutch, while your engine was out. Can see where your clutch bell has rubbed on your spur.
One more thing these guys make bumpers and skids for thunder tiger models but I can't see your model. I would email them to find out if they make bumpers for your truggy, would give you a much stronger front end. If they don't you could just re-drill the holes in the right positions. Check first before buying though.
