Finding Engine for 2002 Malaguti F12 Phantom LC

[coral]

Hello All!

As the title states I am looking for an engine for my 2002 F12, I believe it is the 1PE40QMB but that is air cooled. Is there any place I can buy a complete engine that is liquid cooled? I found this: www.ebay.com/itm/Scooter-2-Stroke-1PE40QMB-50cc-Engine-with-Rear-Disc-ENG042-/362071146572?hash=item544d1f404c:g:loUAAOSwM5RZksjI&vxp=mtr

Does that look like a good engine to throw into my scooter? Will the quality differ from the one that came stock with my scooter? The reason I am replacing the engine is because the crank splines are really warped and some of the components cant even come off without serious damage to the crank. Anyways if anyone has any sources for new engines for my scooter that would be awesome.

Thanks!

Welcome to the forum

Here's the cases you should use scootertuning.ca/en/subframe-crankcase/100188-crankcase-minarelli-horizontal-disc-brake-aerox-nitro.html
They also have all the internals that you might need as well.

I couldn't tell you the quality of the motor you listed, but for the price it must be low quality Chinese. Personally I wouldn't get it, but you're the one paying the bill, so if it's what you can afford now, then get it and it'll probably last for a while with minimal upkeep.

If the splines are messed up just replace the crank. Malaguti engine should be a european minarelli.

That's the thing, I have a friend who works on scooters and said that if you split the engine it will never seal properly again and its very hard to split it in the first place, is that true? I have worked on many car engines and can rebuild an engine but have never done any small engine work/ 2 stroke stuff.

What!? My tgb has a morini knock off style engine. I split the cases and changed the crank a few months ago. If you can rebuild a car engine than you can do it. Post some pics if you can of your scoot now and the problem crank.

The tricky part is getting them back together with the bearings and oil seals. Get a good case sealant like yamalube 4 to seal the case it self. There are videos on this site of it being done. I watched them and figured it out. And I'm an electrician, if your a mechanic you can do it.

People split 2 stroke scooter engines all the time. As long as you remove all old sealant from the surface and use good sealant it'll seal fine.

There's literally hundreds of YouTube videos on how to split the cases and put them back together. Many of them on Brent's channel: www.youtube.com/user/90gtvert/search?query=2+stroke+crank

You'll need to make a leak down tester: 49ccscoot.proboards.com/thread/506/make-2t-leak-tester-ways

But yeah, it's really not that difficult. Don't let what your friend said about sealing them up scare you. I agree leaks are bad, but that's why you make a leak down tester, which can be done for less than 20 dollars.

Thanks guys, I appreciate all of the feedback, the scooter is over in a friends garage right now so I cant post pictures until tomorrow. Ill watch some videos tonight and get familiar with splitting these engines.

I looked through that guys videos and couldn't find anything meaningful to what I'm doing, this is the only video I could find that kind of applies to me: www.youtube.com/watch?v=mWuS_eOHN_8

Anyone have any resources for doing a tear down of the liquid cooled version of the 1PE40QMB? I kind of just want a complete guide that lists everything I need to do, I know that may be a lot to ask so any help is appreciated.

Thanks!

coral, here is a link to splitting the cases 49ccscoot.proboards.com/thread/351.

Here is one on installing a new crank 49ccscoot.proboards.com/thread/1225. Heres one using a heat gun 49ccscoot.proboards.com/thread/1302.

I have split several cases and installed cranks using these links and have had no problem. The differences with the liquid cool is you need to drain the coolant and be aware of any water pump issues. Here is a link to the manual for your scooter en.malaguti-club.com/manual_download.php?id=5. You do need to join the forum to get it. That will help you with specific information.
