If the coolant temperature spikes, it can be very easy to miss.

I've been thinking about how one might retrofit an alarm to draw to an engine heat well before you risk damage.

An obvious thing would be to wire a parallel connection to the temperature sensor and read it with a microcontroller. But I've read that having a second connection maybe could alter the temperature readings? But maybe you could drill/tap a hole for a second sensor?

Another idea I had also involves a microcontroller, that is somehow triggered by the gauge itself. But I don't actually have any ideas of how to do that.

Edit: lowered the price.

So I was embarking on a 250ish mile trip. About 100 miles in, I loose power. I look down at the dashboard, and the engine was all the way hot (it was normal the entire trip). The radiator didn't feel very hot.

I let it cool down a bit, and start it again. The needle quickly goes back to the middle. I drive a few more miles, and lose power again. (Don't remember what the needle said this time).

Now it won't start. The starter motor turns, but it doesn't sound like it's cranking normally.

My best guess for what might have happened is I had a coolant hose loose (has a screwed clamp) for a few seconds by accident after I checked my valve clearances. Maybe it sucked in some air?

Thankfully the engine failed 3 miles away from a uhaul (expensive bringing it home though). It could as easily have been 20+ miles to the nearest town.

The engine oil looks pretty normal, but then this happened *very* suddenly, so I don't think it would have gotten much time to mix with coolant.

How should I proceed? Start disassembling and see what the head looks like?

I've used my scooter to go camping twice.

Both times, a wild animals tried to burrow into my seat. The first time a bear cub, the second a raccoon.

The racoon was especially problematic, as it had no fear of people. I eventually got it to stop after I charged at it. Even then, it just climbed a couple feet up the nearest tree where I could have just reached out and touched it.

In addition to the damage to the seat (not that bad, but still some holes) I'm thinking this is probably a dangerous practice. Next it could be an adult black bear with no fear of humans.

Any ideas of how to not attract animals?

I noticed there was some play in the rear fork/bracket bearing. So I replaced it, but I think I accidentally hit the seal a little bit since I can see the imprint of some of the rollers underneath. There's a tiny gap at the seal too. Anyways that bearing has play in it too, I assumed because I damaged it.

So I just got a third bearing, and decided to check it on the shaft before doing anything... and sure enough there's a tiny bit of play in this one too. Definitely in the bearing, not the shaft. So.... I guess this type of bearing just has play in it by design and I've been worrying about nothing?

Should I bother paying someone to press in the new bearing?

Edit: Whoops, I meant to post this to the People 250 forum.

There's belt dust everywhere in my transmission. I was thinking of loosing it with a bottle brush, blowing it out, and wiping down all the surfaces with acetone. Inside of the transmission case, pulley surfaces (even those these are pretty clean), variator ramps, clutch bell, etc. Good idea?

 Also, I noticed that the clutch spring is rusty. Is this something I should worry about?

My rear fork is stuck to the rear axle shaft. I tried lightly hammering the shaft to loosen it, but I think I just bent the end of the threads. And messed up the threads of the axle nut while I was at it.

Does anybody know what size die I'd need to fix the threads on the axle? And if I can use a non-oem nut?

And possibly how to loosen the fork, which is still stuck.
