25 000 km engine dead.

Hello,
25,000 km, engine dead.
The oil level warning light never came on, but I was completely out of oil.
Upon seeing the spark plug, the dealer didn't want to go any further and declared the engine dead.
Do you know where I can find a technical engine manual for a complete disassembly myself?
Ideally in French. Many thanks for the information.

As I reported back in 2022 (https://www.bmw-scooters.com/threads/bought-pdf-shop-manual-for-c-400-gt-on-ebay.2474/ ), I purchased a PDF version of the shop manual.

This manual is still available on eBay: https://www.ebay.com/itm/133967057090 .

Sorry, it's in English (and refers to the C 400 GT, but the X and GT engines are the same). But it does have some pages that describe in detail assorted internal engine work, with sections titled "Removing and installing or replacing cylinder," "Replacing cylinder with piston," and so forth.

That information might be all you need, if you're familiar with working inside engines. (I have no experience at all in this area, and have mainly used the manual for assistance in removing body panels for my electrical additions.)

Bonne chance.

That is disappointing, it seems there are more than expected engine failures on the C400's.

I still maintain finding a good used C650 is a good alternative to the C400 series: more power and even low mileage ones are not so expensive these days.

Bon chance with the broken engine!

Also (in addition to my post #2 here), did you see the video that @sinosoul referenced in the post www.bmw-scooters.com/threads/fuel-pump-failure-causing-camshaft-damage-wth-is-going-on-w-this-scoot.3631/post-30723 :

This is a little thread drift, but as a former owner of 650 scooters (two Burgman 650s, for a total of 11 years), I would not want a 650 again. And I test rode the BMW 650 once, too, completely unsupervised.

It may be a matter of fitness, age, and inseams, but, at 77 now, I don't want anything heavier or taller (seat height) than my current C 400 GT. And it suits me fine, for both spirited backroad twisties and for the (very) occasional all-day boring superslab trips. And I do want a bike with a warranty, because I don't have a bike lift, nor the time, patience, interest, or expertise to mess with engines and drive trains. So the C650 fails on all those counts for me. I imagine this is not the case with you.

Here in the USA, that leaves the C 400 GT, a Burgman 400, or a BV 400, in terms of scooters more or less in this class, and a host of bikes such as my Meteor 350 in the realm of standards.

Thanks a lot Wspollack for your answers.
I bought the C400 new, and I have this manual in hand. It's an engine repair manual that I'm trying to find.

I already repair bigger engine that this c400 , but need datas and advises to disasemble and rebuild.

Merci

I'm a huge fan of 300-400cc scoots, just like you, and I'm 2.5 decadess less well-aged as you. Today, a retiree and I pushed up the c400 up a truck ramp and he (who rides mostly R50/R60s) was shocked how heavy the scooter was. I'm on a BV400 now, and moving forward, I'll probably be trying the kymco 400i to replace the C400
