Condensation in pipes,

Having found a secondhand set of genuine pipes for my bike I am paranoid about condensation in them, currently when I finish with a bike I have bought some silica gel packets which I stuff up the exhaust semi sealing them from the outside air... I am looking to buy some bungs to seal the ends however given the ethanol issue and all the water generated internally will I just be sealing the condensation in rather than keeping it out ??

Tampons fitted !!

As there is always moisture in the air - I suspect you will be sealing it in.
Alternatively take the exhausts off and bring them into your house.

I have got one of these vacumn bags, comes with a dehumidifying pack - protects the whole bike.
Just about to put my Z1B in for the winter.

The amount of air trapped inside if you seal them up will be tiny as long as you don't just bung them up 2 minutes after running the engine. The problem as always when storing in unheated spaces is warm(er) moist air condensing on cold(er) metal engine/frame/exhaust/wheel parts etc.

I usually just give everything a good coat of wax and then wrap everything tightly with cloths etc to stop the air getting to the metal.

I like to ride my A4 in the winter ( on the warmer days!) so for easy access I "store" it with a greenhouse frost heater under it and cover with a bike dust cover and old quilts.
It only uses a couple of quids worth of electric a week and never gets condensation.

Just ride the bike is my advice :)

avoid running it up too often over winter unless actually going for a ride.
if you do run it try and get the silencers hot enough to encourage vapour to evaporate.
ensure the small drain holes underneath are unblocked and at lowest point for drainage (ie. not on side stand).
squirting some acf in drain holes and exit holes is not going to hurt.
Cheers

I wound up some kitchen roll into a thin strip and stuck it into the drain holes , sucked out a fair bit of water... acf???

I assume you have power where the bike is stored? If so try and make it as air tight as poss and stick a dehumidifier in there.
You'll be surprised how much moisture you'll extract.

ACF is this stuff (ACF-50)

Similar consistency to WD-40 but seems to work better/ last longer.

Will burn out of the pipes without oily residue when you run her up properly in the spring

Yep, I use a X-Dry unit which takes out about 2-3 lts overnight when the residual humidity hits upwards of 60, plus it keep tools and anything else stored in the garage dry.
