As the standard air intake seems to be so restrictive (I read a lot on here) and the answer seems to be to put a lenies on. Has anyone drilled extra holes in the top of the air box above the filter??????? I've just popped a K&N in (Thanks Julian) and it flashed across my little mind.

If you did that, what little ram air effect you might get with the induct would blow out of the holes

Fraggle - I think Bailey runs without a snorkel at all.
Some have tried and failed to mess around with the original intake.
I have considered a dual snorkel (one each side of the engine).

I had the San Jose snorkel which was an improvement on stock. I then bought Gromit's Lennies and it made such a significant improvement in acceleration, intake noise and the speed the motor revs up I was grinning ear to ear. Whatever it is (smoother airflow, less restrictive, resonant frequencies??) it works and quality costs I'm afraid.

.Lennies InDuct and a San Jose Super filter is the answer BUT you have then spent the best part of £500. Whilst we would maybe pay that for an exhaust (that can be seen and heard) It can be difficult to justify that much on an Air Filter and an Intake tube.(Does the job though)

I have my doubts as to the ram air effect on standard with the position, size and shape of the pipe.

Fraggle,take it from me...just remove the whole damn thing so you are left with the filter and clamping ring.
This costs nothing and it does improve things.
There are a lot of air cooled twins that run an open filter system...Guzzis and air cooled Duc's spring to mind.Even the bikes in Sound of thunder/Battle of the twins run the same config!
If you are not happy.....then you must have too much money and need a lennies/SJ filter.
To get it in to perspective:this is a boxer engine that reportedly acheives 98HP at the crank.I fail to see how ram air effect is gonna improve things much alone!
My 0.02p.

Ram air is a dodgy issue, for a start on our bikes the duct entrance is in a location that does not have optimum air-pressure, hence why VTR SP1's et cetera have them between the headlamps.

IMHO I think the Lennie is on best for mass air flow and resonance.

Well i drilled a couple of 10mm holes above the filter last night and took it for a blast this morn (K&N now fitted as well) It lifted the wheel in first unexpectedly. Maybe i hadn't wound it on thaat much before. There were certainly no ill effects

Bailey,
You got a K&N in there or just the bog standard BM kit?
Bern

K&N (+Laser pipes)

bailey do you realy move evrything or are you joking if not does it realy make a difference and what if any harm can it do etc..
also how does it now get the air to through??
sorry im a bit confused
