After removing the system I just installed a 1.5-2” SS bolt; and if needed I just reach under the tank and push the bolt forward.  There is a little resistance when pushing but it’s easily overcome.
If you wish, shoot me an email and i can send you a photo of how it looks.

I’ve had this setup for many years and have only used it twice to start my bike, and I could have just rocked the bike a little and likely started on the second try.  There is no need for me to use it when starting my bike, it cranks just fine without raising the exhaust valves.
This is an easy alternative to do to replace the stock setup, a bolt and a lock nut.
