Aprilia RS50 2004 Oil in Coolant and White smoke

[sajidnazeem]

Hi,
I recently bought an Aprilia RS50 2004. It was working fine, I performed a coolant change as the engine was getting a little hot. There was oil in the coolant. I bought Evan's Waterless coolant and all of a sudden there was white smoke coming from the exhaust. I took the bike to a shop, one of the O ring's burst. I changed the all the gaskets and O rings on the top end. But still, white smoke was coming out. They said it was water/coolant in the exhaust, they said they would drain it or get rid of it somehow. I picked the bike up later that day and still white smoke was coming but now only under acceleration. After 2 minutes the bike just stopped dead. It did not want to crank then after a few tries it cranked but did not start. The bike got trailered to the shop.
Any Ideas of what it could be?
I am planning on changing the water pump seal. but as it why it stopped dead, I don't know.
Any Advice would be appreciated.

On a two stroke the only oil that can get into the coolant is the gearbox oil, which means you probably need a new crank seal.

cylinder head gasket gasket I would suspect.

The two stroke oil from the cylinder is going though the head joint into the water jacket.

White smoke will likely be a cracked head, assuming you've not torqued the new gaskets in properly.

The oil is likely to be crank seals as mentioned.

The cracked head would also explain why you found oil in the coolant.

I had a GFR with the same problem. The white smoke was particularly thick under hard acceleration.

The smoke only started a few days ago, the oil was in the coolant for maybe a month or more I suspect but it didn't smoke at all.

I did say my "entire" post, rather than that particlar bit.

I'm happy to get called out on anything I post, but I feel it's a bit strong if someone takes part of it, summarily dismisses the whole lot and leaves it at that.

If we're now picking and choosing parts of a post, then generalising on the basis of that, its not exactly helping anyone, is it?

Hmmm.... Italian bike, white smoke

Never known a 2T do the white smoke thing when a head gasket fails. They usually just start bubbling the contents of the expansion bottle when revved (and obviously start using water).

But what do i know, i've only had 2T bikes on and off for over 25 years and spannered race bikes for the last 3.
