Hi! My first post here

I was driving on the ice today with some friends here in Sweden.

My rappy just died when I was driving. I noticed something was wrong so I went of the track and it just died.

Tried to start but the engine didn´t turn over. It was stuck

I pushed it on the trailer and went home.

When I came home I tried to start it again and it started after a while like notthing had happened

Any ideas?

Its a Raptor 700 -06 with Barker Dual´s, JE 11:1, Hotcam 2, PC3, dynatek ignition, K&N filter And intake

check the easy stuff first,switches, voltage, sparkplug, do you have the proper map? stuff like that

 

[Finnepower]

I´m pretty sure that it isn´t anything of those things.

The starter coulden´t turn the engine around eventhough it tried.

It was like the piston,crankcase or cam was stuck

Might be a seized crank.

Might want to check electrical connections on battery, starter, and relay next to battery. Mine came loose and did that.

ok well thats different, in your post above you said once you got it home it started again like nothing was wrong. well since you think something is stuck take the head off and see whats going on in there

It was like it cooled down and came loose

Anyone who have had problem with seized engine?

 

[Finnepower]

Took the engine out from the frame today.

Will start opening it next weekend problebly

sounds very similar to the symptoms my friend had with his Kawasaki KLX250 last weekend.

His starter motor would only just turn the engine over, then it would run briefly until it suddenly stopped dead. Then the starter wouldn't budge it for a while. Then it would go again and so on.

Turned out the big end was shot.

 

[Finnepower]

What do you mean with big end?

 

[Ezkymco]

crank end of the con-rod

 

[Finnepower]

Okay now I understand

 

[Finnepower]

What do you think about this:

When I was driving, the ice sprayed the outside of the cylinder with cold ice. The cylinder became colder and shrink(?) vs the piston who was hotter and tried to expand.

Thats why it seized

Just a theory

Sorry for my bad english:

Edit: Its called cold seized

The theory sounds good, but in practice, I think it's very unlikely to happen. I've crashed into ice cold puddles (with lumps of ice floating around on top 50mm thick) and through snow drifts and never suffered any problems.

Most seized engine problems develop from lack of lubrication, excesive heat or old age.

A seized crank is not all that uncommon on the 700s. If you do some searching, there are a few threads here on it.

If that's what it ends up being, you could replace it with a +5 HotRods crank. They are very affordable and will give you some gains in performance.

 

[Finnepower]

How is the quality on hotrod?

 

[wobble]

You will hear mixed opinions on the quality, but many have had good luck with them on the 700s. I ended up putting one in my 700. If you wanted to spend a little more, you could go with a Falicon or Crankworks crank.

 

[Finnepower]

Okay! I will think about that. Witch piston should I use, Cp, je, wiesco or oem?

 

[RaptorDRW]

If u got the money just go with aftermart piston. Much more reliable than stock imo

I agree. I just had mine out yesterday and slushy roards if front of my house and had no problems what so ever with cold water or ice constantly hitting the motor
