I recently purchased a ramflo filter to suit a 1.5inch SU Carbie. And was wondering is there a noticable difference bettween the stock clubman ring type contraption as compared to the ramflo? if so what would the differences be? eg more power/horse pwer, better induction etc etc

i have no idea about that stuff mate sorry- but how much was it? i need a new one for my morrie.

thanks

cost me 35 bucks.

The idea is that hopefully the ramflow filter will not be as restrictive as the old one so your engine will be able to get more air. This means after you change filters you should readjust your mixture as well as otherwise it will be running a bit lean (more air but the same amount of fuel) once you have done this then you should get see some improvement provided this was the limiting factor. ie The limiting factor could also be your exhaust or various other things... but the air filter is a good upgrade so you should notice a difference over the standard one. exhaust upgrade to LCBs and RC40 will get you some more.

i already have LCB extracters and heads, and a decent exaust, straight thru type.

if i choose not to get it tuned, as i never planned to do that when i fit the ramflo, what do u mean by running lean, with more air to the ratio?

for the same 35 bucks, i would much rather have a tune than a ramflo..

anyway, i dont think they offer very much if any performance advantage over the doughnut type while making the carby more likely to ice up.

But compared to the itty bitty single 1+1/4" filter yeah they're better

they sound better too, but obviously more noisy.

be sure to keep the filter clean and oiled or whatever otherwise the foam will shrink and the air can get past the filter negating its purpose

when you say morrie, you mean minor right?
i keep thinking you have a roundnose

how do u keep it oiled? i woulda thought gettin ur mini tuned would cost more than 35 bucks, i was expecting like a couple of 100 or something.

nar, i cant understand why people don't get their mini tuned professionally.. it takes no more than 30 mins..

30 mins @ 70 bucks an hour = $35.. and thats the at the expensive end of mechanics labour

dyno tuning is expensive though, and costs several hundred, but thats a whole different thing.

ahhh i see

You should notice an improvement in performance - particularly top end - as long as you have it properly tuned and that doesn't mean winding the mixture screw out a bit. You will need to change needles to make the difference, otherwise you are just giving the carb a lot more air that it doesn't actually want.

You do notice it a lot more on the HS2 standard filter, I recently put that back on without changing the needles back and it lost a lot of speed and used a lot of fuel.

The best difference you will find is running a ram tube or stub stack of some variety, which is what I do when there is the room. I believe in Clive Trickey's book he mentions that the standard HS2 filter box should be retained (without the element!) since the air horn actually provided a degree of ram effect. Not sure if this is the case on the HS4 as they have a longer carb body.
