bmc race vs race rs

[northwind]

Oh aye, if you get it done on a dyno then it's totally different, they have the hardware and should have the skill. K&N might be slightly quicker to set up since it's a smaller change- the K&N, stock, they can adjust from the current settings, the Race RS they'd really need to change a lot more.

My MPG when commuting is much the same as anyone else... Mine'll drink like Shane McGowan when pushed harder, but that only happens when I want it to. Since I make more power at lower revs, I don't need the high revs so much, so it all more or less balances out. Bear in mind I've got other work done though, can't really speak for just rejetting etc since I reckon there's better things to spend your money on, like the cam swap.

But BMC Race filter look like that to?? *confused* Whats the different with BMC Race filter and BMC RS Race filter?

When you look at www.bmcairfilters.com there is two kind of filters, one that is stock and is a "replacement filter" and one who is a race filter. The race filter looks like a desnorkled stock filter .. right ?

BMC dont directly sell the Race RS filter, it looks like a Race RS with the opening at the top open to the edge of the filter for maximum air flow.

You mean that Race RS and Race filters look the same?

Nop, they look diffrent, the Race is similer to the stock except it does not have the snorkle in the middle, the Race RS has a large oval opening on the top instead.

AS TSM says, the Race RS looks like that picture. The Race doesn't.

Thanks for your answer!

So is a Bmc race filter a good choice? I don´t have to drill holes in the carbs for it to work properly?
Maybe a better choice than desnorkle a stock filter?

I´m thinking about getting a full akra system and maybe the cam swap but its really hard to decide what kind of filter to choice..

I have search on this great site and found lots to read but it hard to find what kind of filter who does the job best!

I can also say that i find the low and mid rpm range most important, i really don´t spend so much time up around the rev limit

Also i don´t find it so good to have so big jets on the bike..

Would be very glad if i could get some help with that, i know because i have read lots of threads that it is guys here who have lots of knowledge about engine mods!

I have a full micron/BMC Race/150DJ. I found that when i had moved from a de-snorkled K&N to the BMC Race, the bike ran worse and hesitated on acceleration, so i cut back the BMC Race so it was halfway towards looking like a BMC Race RS and the hesitation disapeared.

Were that because you had to rich setting for that filter? If you went down to a smaller jet it would have got better?

Well the K&N worked fine, but the BMC Race as stock looked like the inlet was smaller than my K&N. It would be of course that the K&N was cut open a little more than what it should have been at stock. I may still open the BMC a little more and put larger jets in.
