Aprilia Rs 125 Problem..

Hi there im fairly new to this site. my first post...:blink:    can anyone tell me where to get advice on how to change the complete crank case/driveshaft at the back of front sprocket/ infront of rear shock/back wheel? as mines got a fairly big crack in where seems somethings gone wrong and been forced up out of the casing when the back wheel locked up on me but the bike still starts, runs, ticksover? im assuming its nothing majorly gone wrong inside if it still starts? when it happened i thought engine seized but would start with the clutch in but if put it in gear it would die slowly? any help would be appreciated newbie to stripping down a engine. Also any ideas how to split the crank cases when get round to dropping engine out without a air gun? is it possible?

That looks pretty serious. don't run it any more as you could dmage it a lot more. I'm nt an expert on these engines, but if I was going to try my hand at investigating it, I'd invest in a workshop manual right from the get go. It'll probably be the cheapest purchase you make in this saga :-/

i invested in a manual other day been flicking through cant find anywhere were same thing has happened as on mine surely someone out there lol im guessing its either going be new engine(way to expensive) or get this one stripped and replace crank cases at very least depending on damage inside i suppose. read that it can be a task just getting the cases split:hmmm:

A new motor

won't be cheap, but new cases won't be either - in fact it may possibly cost more.

If it were mine, I'm not convinced I'd bother - having a manual is one thing, but you'll need a decent selection of (good quality) tools too (inc precision measuring gear) which doesn't come cheap either (unless you've already got sufficient tools) - putting old components in new cases may prove to be false economy too.

Im not sure who stan stephens is? tried search him on members but didnt show anything:wacko: ive dropped on some crank cases on ebay can get them with a flywheel for 20-25 quid tops. not sure of condition of bearings but aslong as no cracks (as big as mine) then should be getting somewhere. Has anyone cracked the cases without an Air Gun? Is it imminent to use one?

Cheers guys. I looked on stans site said he rebuilds rs250s for 360 quid inc parts seems reasonable? are the crank cases worth getting at 20-30 pound even if need new seals/bearings. I read somewhere crank cases can be specially welded as such is this true?
