Evening all
I'm pulling my engine out (slowly, as I'm doing it on the footpath and don;t have a centre stand, let alone a jack) and was wondering if there are any lesser known hints/tricks for doing this
I know to pull it out the right side of teh frame once I detach everything, but is there any precise order of dismantling I should be aware of? (read something about the chain and clutch cover etc here the other day)
Thought I'd double check before I do something wrong
cheers

Taking off the right cover as a first step came up because Carl keeps the clutch housing from turning when he loosens the nut by holding down the brake pedal.
If the chain has been disconnected (or the engine is out of the bike) holding down the brake won't do any good.
Yamaha says skip all that and put its special tool ($$$) on the clutch housing after the engine is on the bench. Or you can make your own tool, which is quick, cheap and easy. You can do it Yamaha's way or Carl's.
A center stand makes it easier (and more stable) to get to everything, but you can set the bike on blocks of scrap wood or something.
I've had my engine out a couple of times. I put something soft on the floor (say a plastic back full of rags) and lay the bike on it. Pull the mounting bolts (already loose) wiggle the engine free and then lift the bike away from it.
It's a little harder to reverse this and put the engine back in — more wiggling and moving things around to get everything lined up without scratching the paint on the frame.
Once you've done it, it's really a piece of cake. The biggest part of the job is draining all the oil, and removing the battery and gas tank. I don't break the chain, just push the rear tire forward and slip it off the drive gear.

Plastic back = plastic bag (That's how they talk up here in Minnesoooda.)
If you aren't going to take the engine completely apart and the kick-starter is working okay, don't worry about taking off the clutch housing. It doesn't need to come off to replace the clutch, so you won't need any special tools. (Unless you're pulling the flywheel, which calls for a different tool.)
If you replace the clutch you might want to save a few of your old clutch plates in case someday you need to make a tool to hold the clutch housing.

Hi milkbloke,just succesfully completed a top end re-build,first time i've had the engine out.bits of advice:- helps to have a solid workbench to work on once youve removed the lump,temporarily tiewrap the cable that comes from bottom of flywheel/generator,its so easy to get this trapped underneath when your attacking the topend with spanners so tie it up out of the way.if your not sure of putting things back exactly as was i.e routing of cables and wiring,brackets ,take a few digital snaps before you strip it out [how many bikes stay in bits cos the owner cant remember what goes where?] finally,dont rush things and remember all the 'p's---proper preparation prevents pisspoor performance!
good luck, Andy

Just did this a little while ago. The book I used had a nice long checklist.It had me take off all the oil lines and drain the frame. The book did not say or I did not read it to say drain the sump. I did drain it as soon as I pulled the clutch cover. LOL. I was lucky I was working over a plastic lined drop cloth and had a bag of kitty litter handy. I just lifted mine out the right side of the frame. Hung up slightly on a wiring bracket. I removed that and it went back easier than it came out. I strongly recomend a manual. You do have to disassemble all the motor mount plates from the frame.

Mate grit your teeth and get ready to grunt cause the old slug weighs in fairly hefty. Comming out is easier then going in.
