Quick X2 question

[Ignis]

Would a 1986 X2 come with some sort of overheat sensor/protection?

[ebloc]

not that i know of....

[Ignis]

I didn't think so either.

I was at the lake the other day and was riding around. All the sudden, I lost half my power. It was like only one cylinder was firing or something. I got it back to shore and noticed that the main cooling line had fallen off!

So, I was just curious if there was a overheat protection circuit that kicked in that would acocunt for my loss of power.
I havn't bothered checking compression yet, because I got it on the trailer and later that night started it up again. It started easily and ran just fine!

So, hopefully I didn't do any damage.
And yes, I replaced the zip-tie over the cooling line with a real hose clamp. And, yes I know I'm an idiot for not doing it sooner.

it happens to all of us.

Joe, you still want those oil parts? They are still sitting in the back of my maxima.

it sounds like you got a seizure from overheating...hopefully you have not had too much damage

Well I have tore my 89 650sx completly apart and put it back together. This ski has the same engine as yours and I saw no sign of anything to monitor the temp of the engine or exhaust not to mention lack of any lights or anything to warn you on top of the age of the machine so I am going to have to say the seizeure (sp?) sounds much more likely. Mine had the same syptoms as yours did except it was getting hot from running extremely lean with a bad seal instead of the water line.

It didn't seize at all. It just lost power and then I couldn't get it restart on the water, but it was still hot at the time.

After I got it on the trailer and drove it 30 minutes back to my house. Then, I tried to start it again and it started easily. I'm guessing something got too hot, but since it cooled down, it seems fine now.

Just the way it lost power felt a LOT like an overheat sensor kickin in. So, I was just curious because I also didn't think these had a sensor for that.

Anyways, I'm taking it back to the lake tonight to find out for sure.

Yeah it didn't lock up completely it just got so hot the piston expanded and started rubbing the sides of the cylinder causeing that much friction. It just takes away that much power. If you pull the cylinder off you should see some scaring on the sides of the piston. I believe that is the correct explination.

I took it out last night and it ran fine. Luckily!

It's fine for me this summer, but maybe next summer I'll get around to a new top end kit and some minor performance mods like bigger carb and milled head.
