second picture is the rectifier/regulator i think, and the 3rd picture there should be a boost bottle there ontop of the inlet manifold

You seriously need to get hold of a manual for your bike mate.

Depends what year your bike is. The cdi should be on the oil tank for earlier models or under te petrol tank for later ones.

As stated before the metal unit with cooling fins is the regulator / rectifier.

The hole in the rubber is for a boost bottle and the reason for the oil is as follows....

 "Since Carburators can carburate both in and out, when the charge is out of
phase with the engine it creates a double dipping intake charge (passing the
jets twice). This kills the engines ability to make Torq due to this RICH
condition, thus creating the Torq\HP DIP just before the engine starts to
take in the charge and use it all. This Power dip can be seen in both 2 and
4 stroke engines. The ~BOOST~ Bottle will help cure the problem by providing
a storage tank, of the required volume and distance to resonate at this RPM.
It stores the charge that once reversed back through the carb and returned
as a DOUBLE RICH condition."

 

...so basically you allowing this mixture to be chucked out of the top of the inlet manifold. your bike will run poorly and inevitably blow up. It will blow up because you effectivly have a huge airleak around your inlet and so your mixture will be far too lean! I suspect if you have been running the bike as it is, the damage has alreayd been done. I would advise a top end rebuild or an inspection at very least!

 

The "diddy" screw is your air screw on your carb. It usually controls the amount of air thats in your mixture and needs to be carefully adjusted to avoid a lean mixture which can be damaging. In your case, I wouldnt be worried too much as i doubt the slight adjustments that you can make with that screw will have any affect on the mixture because of your inlet issue!

 

I would seriously get a manual and have a read. I hate to say it but I can't see your engine lasting much longer as is =/

Ahh I think I just jizzed at the first paragraph.

I love physics and that explanation there is fooking lush!

Well in that case, please explain it to me lol! I kinda get it but every time someone brings it up i always have to google it and re read a few times. Can you think a way of explaining it simply?

To understand it it's important that you know what resonance is.

Resonance is the dramatic increase in amplitude when an ocillating body is being driven at its natrual frequency.

It's natrual frequency being the point at which resonance occur.

To describe resonance think of this.

When you walk your arms sway. You walking is the driving frequency and your arms swaying is a result of that.

Now when you walk at a certain frequency your arms sway at a greater amplitude than they do before and after this point.

This is because you're now walking at a frequency that now matches the natrual frequency of your arms. Thus making your arms sway at greater amplitudes.

So the above says that this double dip causes power loss due to the rich nature of fuel and oil.

This double dip causes an oscillating motion of some kind.

The bottle is designed to be the natrual frequency of the oscillating motion causing it to resonate.

This counter acts the double dip by giving a surge of air at the precise mixture of the double dip.

To put simply that bottle has been designed so carefully in order for this to work.

Modifications to the bottle without further calculations will cause a loss in performance.

OK cool. I've gone from opaque to transulcent. I'm sure i'll get there one day! Cheers for that mate has definitly helped!

Type in tocoma bridge into YouTube

That is resonance in action. Watching that might give you a better understanding about what the boost bottle does under these couple dip conditions.

Must not be sealing properly. Glad to hear your're not riding it without it lol!

the early models are under the tank bud, the later model dtr they are on the oil tank, where they are on the RE no fookin idea, seeing as not worked on one, which is why I said as far as I know its on the oil tank

 You'll have some poor sod going out in the freezing cold taking off his panels, seat, then tank, to get to his CDI, when all they need to do is take off the right hand rad scoop, early models have the CDI under the seat, and all later models I've seen are infront of the oil bottle.

When I say early I'm talking '89

When I say later models I'm talking RE.

That's usually how it goes.

My bike is a later model. It's an RE. The CDI is under the tank.

My bike doesn't need a cdi.

Why would it??

All it does is sit in the garage being broken...

My bike doesnt need a CDI because it runs off my brain. I just think "Go" and it goes mentall and takes off.

89-99 under the petrol tank
99-2004 on oil tank?
2004 RE - discontinued is under petrol tank.

Thats what i thought.

Either way, its not hard to look through the rad panel to check if its on the oil tank.
If its not is a tank off job.

There are 2 different styles. Are you looking for the right thing. If the bike is running it will be there somewhere lol! Just a thought but werent some of the larger squarer ones located under the seat, like above the airbox?

Follow all of the block connectors from the loom, one of them will lead to it.

Yeah it's not rocket science mate. If you can't find your bikes brain then you really should just let a garage sort the bike out lmao.

 Not as far as i know. I've never see one there. DeeTee is the man to ask. He's seen almost everything s he's worked on a tonne of DT's from all diferent years.

Upload a photo, photos always help!
