I have already stated my bike's capabilities. I have also stated why running at WOT is bad.

I cannot supplant my own 3 decades of practical experience with your opinion, as it contradicts my own experiences, as well as the opinions of other technicians I have discussed this issue with.

You are free to believe whatever you want, regardless of whether you wish to acknowledge the proven reality that running a gy6 engine a WOT is a very bad plan. But no amount of you believing so is going to rewind time and magically undamage or fix the several gy6 engines I have seen and replaced because their rider thought they could ride in excess of 8k rpms for extended periods

Believe what you want, but simply put, experience and facts disagree with you, ESPECIALLY when you speak of small engines such as lawn mowers and weed-trimmers which are mechanically limited to be impossible to run at dangerous redline rpms.
