Sorry I haven't been on for a while, I've been just a little too busy of late. Anyway I thought I would share a little info about my 40k servicing I have been working through.
I have discovered that the Pipercross foam type air filters I have been using must be pretty much useless. Great to clean and oil, reusable and were a great price for two so I could rotate them at my leisure but they don't actually seem to work. During the last service I found particles of sand in the inner chamber of my 00 ST airbox. There is also evidence that the dust has been entering the throttle bodies because of the shiny (not kind of dirty) point where the ports diverge to each valve. I don't think it has been a huge amount because a while back I had the oil analysed and the silicates were within spec, but it just doesn't seem to be a good thing.
I figure that at the constant vacuum pressures the airbox runs at the particles must be able to work their way through the fairly flexible foam. I don't think even the best oil is sticky enough to stop the migration. I think the old wisdom that there is no substitute for decent quality paper filters stack up. The thing I hate is that I have to fork out $80 a time from Triumph for a bit of paper and rubber because no one else makes them.:arghh:
Anyone know of any other alternative to stock? (And don't say K&N...)
PS. I ended up going to BMW for the same fuel filter Triumph sell at three time the price. C'mon people we weren't born yesterday $94AUD for a basic fuel filter??? ($28 Knecht-Mahle KL145 from BMW).
