Aprilia RS250 Help

I still doubt it's seized... Put it in 6th and try turning the engine over by spinning the rear wheel by hand. Probably best to use a paddock stand if you've got one.

Agreed... seems unlikely that it would sieze at the moment you turned it off at a mates place... Turning the rear wheel in 6th is a good idea though... if that turns the motor over, then maybe it simply has a jammed kickstart mechanism.

Same thing just happened to me on a Suzuki GT500. Came home last weekend, all good, praked in the gargre, all good. Now this weekend, it's seized. solid. Solid as. Without being used in between.I finally freed it up, but. Weird.

I had a similar incident...well not exactly. It was on a ride-on-lawnmower.

Was running fine and dandy, then got it stuck in some mud. Turned it off and went to get help to tow it out. Came back and it just wouldn't start (can't remember if it would even turn over).

Turned out to be a seized crankshaft. It somehow got hot enough but the constant movement kept it from locking up. Once it stopped the crank seized completely.

Strange but true.

Hope its not the cause of yours

there is a new aprillia shop at the mount on newton st, could get it checked out there. I would definately say get it fixed could mean the diff between 3k in parts or 7k of bike.

I had the same thing happen a few years back on a RGV, I have no idea what the problem was (I do have my suspitions(SP)) but all I did was put it in gear and rolled it backwards, went fine for months after that then i wrote it off...

I suspect it was the piston catching on the power valve but I never pulled it apart to find out..

With regard to putting it in a high gear, and effectively forcing it to turn over. It could be a bad idea. I've heard of people on CBR250's trying to pushstart their bikes, with hydrolock from flooding, and it's broken their engines badly. I'm not saying you've got hydrolock, but if something's jammed you could end up doing it more damage, like maybe breaking conrods. I don't know what is wrong though. Best bet is if you're not going to strip it down yourself, then take it to the bike shop and get them to sort it. You'd probably be better off taking it to a well known twostroke mechanic, as somebody said, most bike shops mostly do 4stroke work, so I wouldn't trust them with a two stroke (unless you know they are good at it).

That's why I suggested spinning the rear wheel by hand rather than pushing the bike while in gear.

You would have to be a fucken rough cunt and swing off the wheel pretty damn hard to bend a conrod by hand.

I could take a look at it next time I'm in Tauranga. I might scratch my head a bit then tell you I don't know, or I may be able to get it going for ya.
