You be glad you have a throttle if you crash and burn like I did a year ago.
Here's my side of the story,
I was riding along one of my cow paths, (my favorite type of riding) as the roads are deathtrap around here) out of the thousands of miles that are around here, on a steep side hill, came upon a couple of cows plodding along, heading for water from the spring up ahead about 1/2 mile, followed and kept crowding them, one of the cows stepped off the trail and I pasted by it OK, with no problems.
As the second cow stepped off the trail, I started past her, she dropped her head and acted like she was on the prod, and wanted to hook me, she took steps towards me, (was less than 6' away), I took evasive action and then slide off the trail and ended up in a pile of pucker brush and rocks, about 10/15' downhill from the trails edge.
When I finally got up right and untangled from the pucker brush/rocks, It was then I found out that I had really torn my right shin up almost to the bone, from the rocks and brush.
Then the reality set in, I was between a rock and a hard place,
(over 5 miles from the nearest road), I finally got enough bandages wrapped around the mess, to stop the bleeding, all the time watching the cows which were standing less than 10' away, watching me.
After about an hour, I finally got John Wayne (bike's name) back up and onto the trail, checked the bike, no damage done just a few scratches, but my leg hurt so bad, I wanted to pizz down both sides of my pants legs at the same time.
I found out I could barely stand up and couldn't peddle, like I normally do. I finally got a leg over the top bar and used the throttle to get me home, so the better half could haul me to the emergency room to get patched up.
Imho, I would never remove the throttle from my bikes.
I would disable the plug and seal the ends to prevent moisture,
but leave it attached, so you can use it, if needed in the future.
By sealing both ends, you have shown intent to comply with their rules, and the throttle cannot be used, and ride like a normal older rider would. (I am 77 and ride like an old person also)...Lol.
ymmv
