any difference in power with a k and n fitted
Personally I think the only place you'll notice a difference is in your wallet Yes, if you do a lot of miles, you'll eventually break even with a K&N over eg a HiFiltro pattern replacement, but the difference is marginal.
It's simple maths that you will save money with a K&N.

So that's 100,000 miles before you break even. Simple maths.
If you leave a paper filter on for 25,000 miles your bike will not be performing at its best capacity.
Have you not seen the state of windows, or even vehicles, after it rains these days? The rain has thick dust in it. You can blatantly feel the engine breathing better as soon as a K&N is fitted.

If you leave a filter in place *without checking it* for 25,000 miles, you've only yourself to blame.QuoteHave you not seen the state of windows, or even vehicles, after it rains these days?

Ok, this is just going round in circles. You want K&N and you think it will benefit your bike, pay extra and buy one. Personally, I don't think it's worth the extra cost and hassle. Your choice.

Have you tried one?
I wouldn't leave a filter on any bike for 25000miles and I would be surprised if Haynes said 25000 miles since they take their information from the Yamaha manuals and the Yamaha manual states replacement at 12000miles 19000Km.
Quote from: darrsi on 21 September 2022, 07:12:05 pmHave you tried one?No, because I don't feel the need to pay four times the price for something which would most probably make no noticeable difference to my riding.

So how on earth can you comment on them?

If you want to spend the extra money, feel free, but, like upgrading my rear shock from OEM to YSS instead of Nitron or Hagon etc, for the majority of riders, the difference will probably not be noticeable or beneficial.
Give your bike a treat, you never know, you might even like it.
