Took off Petrol tank, realised I have the XT600ze, 87 model with the air filter taking up the tank space. Anyone know the useable fuel capacity?

Air filter has lots of oil in it. Cleaned the foam air filter, and noticed that a down pipe had become disconnected going into the engine/gearbox. I assume that this is where the oil comes out.

Then I noticed three down outlets from the black plastic box, with only one having a pipe connected to it (Inside one is blank) and the left one sort of pinched pipe blanked off. Is this right?

Did not disassemble the carbs! Reconnected (alarm bells!) all the pipes from Air filter to the carbs and tightened up the cable ties, made a note to replace with clamps. Reduced (anti clockwise) what I take to be the idle screw, and upon starting later it was all good (ish).

I have a sort of switch that I have no idea what it does. Its located on the inside of the right hand indicator mount and its sort of lame. I have a suspicion that it has to do with the electric starter, but cant figure it out it was connected to something with a nail… Being as this looked very compromising, I removed the nail. Needless to say the electric starter has not been working of late, whirling around merrily, but not firing. (Foot starter works fine)

Minor Big problem, both exhaust header pipes have now sheared off it was all very spectacular and the local kids watching shat themselves at the blue flames, woo hoo!: How do I remove the seized clamps? in the UK, and soon? Croydon or Rochester anyone?
PLEASE
Then where do I buy another down pipe cheap, alternatively get this one welded nicely! at Quick-Fit

Now noticed that the oil filter plate, looks to be a dogs breakfast, clearly one of the screws has been stripped (bottom), and is glued. The second has had some sort of DIY job done on it, and looks like the corner had broken off. (top left) the third screw is fine. Saw some oil coming out of here, so may have located the leaks. Bit there still looks to be oil coming out elsewhere. I am not too perturbed at this stage as it will become a mechanical project.

Interestingly the prospect for macro photography with a bike engine is quite huge, so I will endeavour to post many pics. At this point it was only observations.

Hi again,
This sounds like a "one step at a time" job! You definitely want to get the manual for your year of bike, Clymer or Haynes.

In the meantime, you may like to read this:-

If you look back at other posts in here, you will find reference to an online manual for the XT (posts by "Dakota" or "Smoking Lizard") - I don't think it will cover your year, but you might want to get some background info from it.

Cheers,
