I already put a serious amount of wear into my new starter wheel. I've never seen a new motor this tight.
You need to heat it up to about 100Degrees celsius and start the engine with your starter box. Make sure it is at BDC before you hit it on your starter box.
If that doesnt work, you need a more powerful starter box. Im using Mugen starter box, it has dual motors. No problem starting the engine for the 1st time.
