bmc race vs race rs - Page 3 - SV650.org

I had a Renegade airkit... One of the worse purchases I've made for the bike. The filter's poorly designed, it sticks above the airbox so that if you don't use tank spacers, there's restriction, but the kit doesn't come with the spacers. Even with that fixed, it doesn't flow as well as the BMC.

You do get a set of airbox trumpets, which are very rare to find for the SV- I've left mine in, but I'm unsure as to what difference they're making. Not a great deal I suspect, at least not with the rest of the airkit fitted- there's no midrange boost as you'd expect, I suspect they compensate for a midrange loss rather than giving a gain... But I do wonder what they do for a properly jetted bike with a system and filter. I'll find out some day. Other than that, all you get is a drill bit and 2 jets.

Also, the instructions included with mine were awful, a bad photocopy of a photograph and half a page of poor directions. Now, I will say that when I came to fit it, I contacted the company and spoke to Jorge, and he was excellent over the phone- very helpful, and apologetic about the instruction sheet... Gave very good, simple instructions too. So from that point of view I wouldn't hear a bad word against the company, couldn't have been better.

But in terms of value for money, it gives worse results than a K&N and a pair of jets, and costs twice as much.

Dyno run here:

But remember that's crank not rear wheel.

I was very disappointed... The K3 airkit is a totally different product, and rather cool, but this one's just a failure if you ask me. If I was Jorge I'd drop it entirely, since it doesn't measure up to their usual standards- if I'd been thinking of getting one of their systems, I wouldn't after getting this. It happens that I know they're a great company, and they just happen to have a bad product here, but not everyone would come to that conclusion. But then, Renegade have always been a bit like that, the standard of the website tells you that there's some strange business decisions going on.

Kinda looks like a used condom don't it?

I thought the airkit was just a pair of jets, a set of velocity stacks and a piper cross type panel filter. Which seems it was.

I had a BMC air filter, but I flogged it as a cut out OE filter works just as well. I haven't spent enough time setting up my jetting for the "de-snorkeled" filter but once my full system arrives I'll maybe fiddle with jets again.

The rubbery finish? It works well... Why would you want a good looking filter, it'll only cost more money

Race RS is just slightly better than a desnorkelled standard filter, btw. Not much, not worth £50 more anyway

I was gonna go with DJ155 jets, for the snorkel and full system. The next size up I've got is 165 then 175. So might have the means(and the mains) to get it to run a bit meatier.

180DJs in mine now

One of the reasons I've not gone to pods, it's taken that long to trial-and-error my way to a setting that doesn't make the dyno man laugh, I don't really relish the idea of doing it again!

i meant where it has been moulded, there are small holes in the rubber. i would not be very happy if i shelled out the full £60 for it.

i now have the choice between the bmc & the k&n. am i likley to get problems with the bmc? which ever i get fitted i will have it installed with a stage 1&3 dynojet kit set up on the dyno. i am not really interested in gaining alot more power as my bike is supposed to be 33bhp and it feels quick enough already. is it worth getting dynojet and filter fitted?

TSM · 19-12-06, 08:27 PM

I have a full system and BMC Race (not RS) and DJ150's, with the stock opening on the BMC the bike would hesitate at 5-6k when you opened the throttle, i cut the filter a little and the hesitation had gone. So its still a little restrictive possably. I need to increase the jet size though and see where it goes.

Wee bubbles in the red rubber stuff? The BMC's built for function only, cosmetic flaws just aren't an issue for a performance part like that really...

Frankly, if you're not looking for power it's probably not worth either

BMC's slightly harder to set up as it's further from stock. Also, you may well end up falling in the big gap in jet sized that the stage 1&3 kit has. TBH if you're doing it for throttle response, you're going to want to get it dynoed, you need it spot on to get that really nice feel. You can get pretty good results by butt dyno, but you need either experience, patience or luck to get ideal results.

i am not saying the filter looks bad it just looks like it was built by a 5 year old. would it be easier to install the k&n. if i put in the bmc would it drink fuel. you say experiance, patience or luck. surly if i got every thing intalled on the dyno then it would be fine?
