Well I finally got around to fitting my new tyres. What a Bastard it's been I haven't changed a tyre for about 12 years.
I'm a little worried the last time I run a ribbed tyre in I came off mid corner. :-[
Watch this space
All this talk about pipes recently made me look at mine the backs were totally smothered in crap and tiny rust spots so of they came and 6 coats of polish latter they now look as good as new.On removal about an eggcup full of water came out of the weep holes and I had only used it the day before.Maybe I should stop using the bike in the rain if I want these pipes to last.

he water wasnt rain mate its condensation from exhaust gases, there is a man local to me who has god knows how old 500 four original pipes that come off every winter and get stood in a 45 gall drum of old old, smoke like a b*std when first started but no rust or rot!!!

Hi Brian I know the moisture in the pipes is condensation I just couldn't believe how much was in them considering I had only used it the day before.
The pipes on my pegaso rotted out due to condensation but it was shearing the garage with the tumble drier.
I just couldn't believe how much rust had appeared on the outside mainly were you can't get to them when fitted

It's worse than that (water) the by-products of combustion are effectively a mild acid, that's why it gets to the exhaust steel so easily.
And it's even worse than that, when you see rust spots on chrome-plate it's not the chrome that's rusting. Chromium does't rust, that's what makes stainless steel "stainless" as it's alloyed with steel in various percentages to gives different levels of resistance. The rust is from the underlying steel that is corroding and passing through pores in the chrome so that you can see them.....that's why Bryan's local 500 guy has got his pipes to last so long by nuetralising the acid and excluding the oxygen.
The best you can do when in use is to run it as close to lean as reasonably possible for less unburnt fuel and never switch off and park it unless the pipes are really hot.....rain on the outside doesn't reall do much except cool the pipes and help cool the gases inside to leave the pipe's condensation inside the pipes and dripping out the drain holes.

Theirs no fear of my bike going away cold if I use it it's normally a minimum of a 50mile trip one way.
I think the biggest problem is I never seem to have the time to clean the bike as much as I would like.
