I would agree with that; I've put the tea caddy on both my bikes and it looks much the same as the original. And you do get the use of the tool box. I also like the idea that the air filter is just that... not a "dummy".

Alan R - had a look at that breather mod kit - but still a bit confused!!

The blurb mentions the "oil tank" - are they talking about the sump, as mine is a wet sump? Also, they talk about "wet sumping" - surely this is for an older model with a seperate oil tank? Also, would the crankcase vent through it, as I thought the breather needed to have a one-way valve to prevent "sucking in" air?

I do like the look of that air filter box - a great idea - wonder if induction noise is any greater without that expansion box?

Chris (Stockport) - thanks for the tips - releasing the RH toolbox for tools would definately be an advantage - think I'll go with that idea.

Unless your 2008 model is a UCE (I can't remember exactly when they started appearing) it is supposed to be dry sump

Would I be right in thinking the uce doesn't have a push fit exhaust? Cheers, Chris

Norm - thanks for bringing this to my attention - I had ASSUMED that, as the filler cap appears to go into the crankcase, the engine was a wet sump!! Reading a little further into it - it appears that it IS indeed a dry-sump engine - with an oil tank built into the crankcase. Now I can begin to see the advantage of that Filler Mod that has been recommended to me!!

In case it isn't apparent - I was never into British bikes - just Jap stuff - which don't seem have these devious foibles!!

So, to remove the PAV system, I blank off the exhaust pipe stub and also the carb intake stub - and connect the crankcase breather hose to this Filler Mod device? Other than removing the now redundant bits - is that it?

All you guys input is invaluable - as I am finding it a steep learning curve!! Thanks very much (till my next help question) !!!

Mike, the breather mod is usually used after all previous mods have proved to be still wanting. Many variations have been used some with success, others not so good, just ask about breather mods and you will get a flurry of answers. For starters, plug the exhaust,the small hose into the carby manifold and the return line into the rear of the timing cover. If you leave the catch can in place run the hose to this over the frame crossbar, not as the factory fitted it running under because this forms a trap and the emulsified oil sits in the bottom of this trap and then your breather issues become a nightmare

Hello again, matey !! ----------- "Now I see" said the blind man to his deaf daughter !!------- Might I offer 2 GOLDEN RULES to be successful in Mechanical Engineering ?? (and please read these with a happy smile on your face ??)----a) Never ASSUME anything, and ----- b)Take up Ballet Dancing, it's less stressful--- especially where Enfields are concerned (LoL !!!!!)..... Finally just a slight correction for you }---- the oil tank is built ONTO the crankcase, not INTO it. ie it's a completely separate oil container that's part of the crankcase casting as a whole.....BTW, My 1997 Suzuki Marauder 800 has a PAV-type system on it. ( yes, it's a Canadian import one--- but was fitted as a standard item). The truth is out there---somewhere, Scully!! ( PS--- if you CAN stand on your kick-starter then I think your engine has seized up !!)......... Have a nice day .

Norm; Sorry mate but I think you might be confusing Mr Yamamha. The return pipe to the back of the timing chest is from the catch tank which is part of the breather system. This is nothing to do with the PAV system. It did seem from your post that you were saying that the return pipe should be sealed as part of the PAV removal.

[Norm]

Peter, you are right it's a bit confusing but here is the story, first you remove the PAV, then you fiddle with the breather because you are getting mayonase in the filler cap and then the catch can blocks and oil spews into the air filter and then you decide you want the toolbox back so you fit a tea caddy filter then you have to rejet the carb and the tea cady falls off, gets run over by a bus and it is now a pancake and then you want to fit a shorty exhaust because you are sick of barking your shin on the original muffler sticking out the back , six inches past the end of the bike and because you have fitted the shorty muffler you have to rejet again and then you decide to change the header pipe because you don't like the look of the PAV plug on the header pipe. You know the story

HI MIKE on my 2008 CLASSIC 500 BULLET ifound my exaust port was carboning up and a slight rattle
i curred this by filling the hole in the bracket oval where it bolts to the down tube
this allows the exaust to push in fully home macking a gas tight seal ATB JOHN B
