Removing your motor
 

I should have made this thread when I did my 700 conversion & could have supplied better photos.

Fran has asked me for this, so here it is.

1/ First thing is disconnect the battery neg terminal.

2/ Drain the oil from the frame, then from the sump plug on the motor, tighten up the sump plug.

Remove the oil pipe next to the sump plug. Watch out for the Oring on the oil pipe, do not loose it. Place the oil pipe into a plastic bag & tape up the bag, so oil does not spil on to your floor

3/ Drain the coolant.

Follow the photos for the next steps.

4/ When it comes to undo the engine mounts, the last mount to be removed is the top head mount 3 bolts. The motor must be supported by a jack before removing any engine mounts.

Nice one Kev! Out of curiosity does anyone have an idea on its weight? The bikes total dry weight is 165kg and it would be interesting (perhaps irrelevant too) to know how much of it actually comes from the engine.

Cheers!

Kev made those "how to remove an engine" instructions for me as I changed the motor on my xt with the help of a friend. I didn't weight the engine on it's own but let me tell you this, with the engine off, I was left with the frame, the fork and the two wheels attached, I could lift the whole bike with one hand effortlessly. It took me and a friend to lift the complete engine to install it!

Ok, I could carry it on its own in a box, squatting carefully to standing position, as I did when I bought it, but it was like a weight lifting competition!! That is where the bike weight is. in the friggin' engine! Damn that engine was heavy. I'll never forget it.

I agree that motor is damn heavy.

So even if you put is on a heavy diet it will never be a very light bike I guess. Could we also say that a heavy engine is likely a more reliable engine? I mean how far could an engine like this go considering that money is not a problem and you could change it internal parts if needed? Just another useless curiosity

We've had people knocking on 80'000+ miles and still going. Mine would have gone further if the thieves hadn't taken it from me. :089:

80k miles is more than enough for few trips around the globe. I had a bike stolen once but it was fortunately insured...damn thieves!

Here you go the motor weight & spec's.

.
Its about 39kg

I have been told....

Haven't removed my one yet, but the instruction are tip-top Kev..

Feels like a 100KGs when you pull it out by yourself.

Yeah, I know a song about that.... :sweat:

Thank you Kev :notworthy[1]:

I have used your guide to replace the engine what a great advice it was :woo:great thanks.

Top man

And some! According to the Motori Minarelli flyer (English version attached) it's 51kg without oil!!!
My sons KX65 had a dry weight of 57kg!!

Glad it worked out OK for you.

If I can get a reading, I will,....the 39kg I quoted was for an older carb'd engine......

is it "doable" on your own Kev?..with a bit of common sense? or logistically a big no-no?

I done the job twice, first time with help, 2nd time on my own. I would say get someone to help you as this motor is very heavy.

ok ty....but i got it in and out of a car ok, but I suppose getting it out of a frame is just a little trickier.

I'll get a helper, ty.

Hello

Does anyone know if its possible to remove the engine with the headers attached?? I cant get the bolts undone :(

Thanks

Thanks for sharing that Kev very useful and exactly what I need to take my motor out this weekend, will save me a lot of time I am sure.

I'm pretty sure you can remove the engine with the headers attached as I am buying an engine with them still on.

Phil

Took my engine out with headers attached last night. It took a bit of twisting about to get them past the front of the frame and I had to remove the oil pipe from it. Also you need to remove the 2 bolts which attach the exhaust bracket to the frame but apart from that it's no different from Kevs guide (which was spot on by the way thanks kev).
