Re: Aprilia Rs250

But thanks for the heads up ill have a read and see whats what before stripping

Re: Aprilia Rs250
Ok so the crank seal has a lip on it which means to replace it you have to split the cases.... oh well

Re: Aprilia Rs250

Dropped the engine out and test fitted the new brakes.

Re: Aprilia Rs250
finally got round to taking apart the engine and today started the rebuild. Managed to sneak it in the house so i could work in the warm. Surprisingly the Mrs was fine about it.

Re: Aprilia Rs250
Have you managed to locate the source of crankcase leak yet Rocket.?
Also, I think I'd be tempted to renew all the bearings whilst you're stripping the crank. There will never be a better time, and their life is finite on a 2T anyway.

Re: Aprilia Rs250
Definitely change the bearings.. RS's were renowned for heat seizing bearings and spitting riders off at 90+mph

Re: Aprilia Rs250
Crank case had been split before. And not sealed correctly. I could see we're it was leaking when I split it.
It's not as simple as changing bearings as they are welded cranks and really need doing by a specialist. So I checked the crank and it's well in the tolerance so it'a gone back together. About 3/4 through putting the engine back together and then I will pressure test it.

Re: Aprilia Rs250
Fair enough mate, if there is no discernible wear on the mains or big ends then it would have been a waste of time & money. Sorry if I was stating the obvious, it's just that bearings used to fail so quickly that I used to replace them & the crank seals almost as a matter of course when a block was split.rocket wrote:..... I checked the crank and it's well in the tolerance s......
But that was usually on singles, and a far more straightforward task. Back then even decent bearings & oil seals together were cheap as chips too.

Re: Aprilia Rs250
Over Christmas and new year i have been mostly been drawing this.
i figured it would help me understand the wiring better and if i ever needed to look back at a later date it would be easier to work out what I have done.

Re: Aprilia Rs250
That looks proper!

You should get some "RStrines 250" stickers made up for this bike, going to be a beast on the back roads.
