Hey JMo :039:, I wish my woman was as dirty as that air box of yours :seasaw::Gangsta2_9BI664:

(nb. any more jokes about me having a dirty box and there will be hell to pay with a pro-motion tyre lever oops upside your heads! x)

30 years of working on motors tells me something different. Might not break down, but might start using oil over time, not good for it.

Yes, I apologise for my slightly flippant attitude in earlier posts, and appreciate both your and Dino's concerns...

The bike has performed excellently up until now (and continues to do so), and I would hate for it to become less reliable a companion.

I would say that I have stuck to the service regime and used only genuine Yamaha air filters each time they have been changed, together with periodic emptying out.

It was only after this last weekend when I removed the filter to shake it out, that I noticed this ingress of very fine dust. The Yamaha filters (and service schedule) are meant to be good for 12,000 miles - so either the filter has started to fail, or there is a sealing problem. Either way, I trust the warranty on this machine would cover any subsequent long term damage?

I will mention the issue to my dealer when I return and the bike is due for it's 24,000 mile service.

When can i buy the dna one and two kit from this site?

for the time being send a pm to DNA and he will probably give you a discount.

But I am waiting to hear from him as to when we can fire up the engines....

Today I changed my k&n stage I for a dna stage I. You can feel the difference I can tell. As for offroad events I always use the original Yam side cover and remove the DNA stage II cover. So with only one filter element to pass air in this case, I want the best filter there is for my modded engine: DNA!

Thanks again Dino.

ps, Will this stage III be suitable for offroad events also?

Greetings from Holland, Marcel

Went offroad last Wednesday with lots of fine dust and sand. Today I inspected the air filter case to be sure everything is ok. Looks great! The DNA has done a great job.
