New 'zorst and K&N Filter.

[DanAbnormal]

Alrighty there,

Bought a Remus Revolution Carbon can and also a K&N filter for my K5 650S. Will it need to be remapped?

Ta very muchly,

Dan

i know you can get away with the exhaust, but when you change the filter ive herd off a few people that a re map would be advisable.

What fine taste you have Dan...

No, you won't need a re-map ;)

[DanAbnormal]

Hmm,

So I have one who says yes to the remap and one who says no. Hmm. Guess i'll have to suck it and see. Cheers though.

To get the best out of what you have, yes....

Question. Why would you perform a breathing modification which won't have enough of an impact to remap? End can, fair enough, but if the K&N doesn't flow enough additional air to require a remap, is it worth fitting?

[DanAbnormal]

I never even considered that. A good question. In other words will the K&N filter warrant a remap? Surely a K&N filter for all sv650's are the same.

How will I know if a remap needs to be done once fitted? I had a bandit once and fit a K&N and it was abundantly clear that thecarbs needed re-jetting but this new fangled FI is a whole new kettle of ballgames.

I understood that the whole point of a K&N (or BMC) performance air filter was that it raised the air flow....

If you put a "race" can on, you can get rid of the gasses quicker, but as there has been no increase in the volume of gas going into the chamber, the gains are negligible. However, fit a "performance" filter, raise the airflow and the volume of gas should go up (theoretically)....

Because it works out cheaper in the long run (I think)

[DanAbnormal]

Aah Carsick you mean because the K&N has a lifetime (1000'000 mile) warranty. So I'm thinking that the filter allows more air to be sucked in, requiring more exhaust gasses to be expelled which will be taken care of with the race can. My understanding of engines os not at degree level so I may be wrong.

Dan

[Carsick]

Yes, I put one on so I didn't have to keep replacing the filter.

Your understanding is fine as a start, but you then need to add in the fact that a faster airflow means more fuel is required, and that's where the remapping comes in.

As the others have suggested, if you want the best from your upgrades, then get a remap. By all accounts, the SV could do with a remap as stock, anyway. The worst that happens is you waste £50 or so, the best that happens is you have a well set up bike to enjoy.

And the bestest bit is that you can get flames shooting out the back on over run :twisted:







Sorry, I was just being juvenile wasn't I :roll:

[DanAbnormal]

OKay thanks a lot guys so a remap is a resounding yes. Next question..........will it invalidate the warranty with the K&N filter plus remap. I phoned the dealer and they did not know.

Yup, ought to do, since it's washable. Good point.
