engine removal

[insane1400]

Hello everyone,
I am in the process of stripping my bike to repaint the frame.

Does anyone have an "at home with no hoist" way of removing the engine from the frame? I have a trolley jack, scissor jack, bottle jack and the normal tools.  Also I DONT have any large strong friends that could help.

thanks
Andrew

Check out froudys post on doing the same thing.  If I find it I will put a link up.

Have a look at this to give you an idea of what's required.

Agreed. Have done engine out twice, while bike was on wheels. I was using manual palette truck, and it was not east. Problem is, you need to lift and rotate engine, while installing it back.

If you would strip frame compleatly, it would be easier to place engine on a side, and rotate frame around engine, to find right position.

the problem with this is that my frame will be freshly painted.

Im thinking to make a jig that picks up the front two mounts, put a jack and packers or whatever is required at the rear and then take the frame out and leave the engine exactly where it is resting now. Any thoughts on this?

Mount a block (of block n tackle) to garage ceiling beams / joists, use this to rig 2:1 or 3:1 (or more) pulley system to help with the lift.

This is what I came up with and it worked really well. The engine sat rock solid. The biggest problem I has was that mutha fu$$er airbox....(it wont be going back on) Two ratchet straps and maybe 20 minutes later..
I have only had the bike about 3 months and honestly I have been very lazy checking it out, when it came to take the chain off I found the front sprocket was loose in every direction, I will remove it tomorrow and see what it looks like.

Your jig looks good Andrew ... well thought out. What drama's did you have with the airbox? Apparently they're a bastard to tune without one. If you decide to keep it then remember that it goes in the frame before the engine.

 What drama's did you have with the airbox?  Hey Snapey good to hear from you. Why would removing the airbox make it hard to tune?
  The drama was that the airbox had to stay in the frame, just heaps less room than there could be if suzuki made it removable, or even if they didnt have the hump in the top of it.

@insane1400  - the jig is nice fella - could you do me a favour if you can and take some measurements

Im about to remove the engine from mine and this would be well handy

Many thanks

With sensors & a wiring loom in the way getting the airbox to slide back far enough for FI removal is difficult but not so bad with my sheet metal trick. Bloody poor design but we're stuck with it. Once the injectors are out then tie the airbox back with an occy strap & it's out of the way for engine removal.

Tuning the bike without the airbox is difficult is why I said "apparently" as I'm going on what I've read. I bought a GPZ1100 many years ago that was fitted with pod filters and even one of the best engine tuners in Sydney had no success getting it right. Maybe ask the question in the fuelling section where someone will give you the answer because I don't know.

Using pod filters not an airbox gives a lot shorter intake track, that means the airflow in the throttle bodies is more turbulent. Hence they are harder to tune, as they'll tend to run rough & have flat spots.

Hooli, i trust and believe what you say. Just interested as to how so many car motors, older bikes run fine without air box to calm the air intake.

maybe ok for carbs & not so much for fuel injection?  just a guess, I know nothing, as mrs Col will gladly confirm.
