Instead of the button screws that hold the plate on for the oil spinner, I took the plate, and added a angled recess to it and then put flush bolts in there. I also ground off a lot of the lip that goes around it for clearance. That lip adds some regidity, but it doesn't need it...there's no pressure on that thing. So if you need clearance, you can cut that down quite a bit. As for your throw...there's more than one way to deal with that. You can find a thicker bearing, you can replace the throwout cage entirely and replace with a Honda Nice version (bigger and thicker bearing), you can machine a 2-3mm ring and put it in before the bearing. I think when I built my poor man's nice, I ended up using a honda nice cage and bearing instead of the stock trx90 one. I also once busted a honda nice one and replaced it with a TRX90 one and had the same issue with throw. I eventually replaced the cage with the Nice one.
