I'm glad somebody saw the humor in my post. Man guys lighten up, this is supposed to be fun.
Just kidding on the X2.
I have always used the King Headz extended mounts on both the buggy and truggy, but now I'm having a little problem with the Losi brand quick change mount. It seems to be a little thick and the starter wheel won't reach the flywheel very easily on my 2.0 buggy. The starter box bottoms out in travel and the wheel is hitting both sides of the chassis and I can smell the rubber burning off the wheel. I did modify my Losi starter box with OFNA internals, but never had an issue with the first gen buggy or my truggy. Now the flywheel is sitting about .025" higher in the chassis with the Losi brand mount. I guess I will have to measure the diameter of the flywheel on the 2.0 (I would think it would be the same) and both thicknesses of the Losi mount and the King Headz mount and see if they are different.
As for the alignment marks with the King Headz mounts, one of the Losi guys showed me a little trick to help keep the motor in better alignment. He said to loosen the motor mount bolts with the car on it's rear wheels at a right angle to the surface the rear wheel are touching. The front wheels are aimed straight up. If you keep pressure on the motor towards the rear of the car, you are using the bolts or the cupped washers as an alignment guide to keep in the clutch bell in alignment with spur gear.
