Hewzer, thanks for putting up the collation of 24/7 by Frits.
Absolutely legendary stuff.

Boy, did I write all that stuff? I suppose I've earned a piece of apple pie with my coffee

[wobbly]

Strudel , where you are now Frits

I have recently became very interested in Frits's 24/7 Inlet system and I am now kicking myself for not saving all Frits and others posts on the subject.

If someone asked Neil H nicely i am sure he could make DP (Neil B) a Sliding Weed valve like this one

Just wonder if old mate Alex wouldn't be a lot better off with a turbocharger. No direct mechanical parasitic losses and also raises the overall in-cylinder pressure at the time of EPC due to the back pressure of the turbo.
Dunno if one could get one that is small enough, but he could make one, adding a variety of spice to his adventures.

i think it was basically std but not 100% sure though.



it could have freed up a bit of spare time for Fits and Jan just those pesky rules prevented bolting on a few snails.
Oh look they did a 50cc as well

I must admit I was reminded about Frits 24/7 inlet system by 2stroke stuffing video's but I could not remember it's details. Thanks for the help, O Great husaberg
I am interested in the Kart company that experimented with this system and found 10% increase over it's full time reed valve inlet system. I wonder if this was only
at the very top of the rev range or did the increase start earlier? either way interesting stuff! and I must say the Norwegian has almost Kiwi level of "lets try
something weird and see what happens" keenest, which I think made his video's so interesting.

He says the rev limiter is set at 13500, and that this is at least 1000 too low.

Mr Overmars will be able to provide details for what where i would suggest or at least point to in the right direction to Rolands and others tests

Added power through the same stingerdiam also raises backpressure.

A crude way to raise the back pressure and still have the parasitics....

I am not at liberty to divulge more than I already have. Roland has been doing most of the work so it's only fair that he will decide how much he is going to reveal, not me.

Fair enough, about Roland's work . I only asked because along time ago I read (probably on this very thread!) that one could increase the bottom end power on a Two Stroke Reed valve by using "Softer Reeds*" but one would have to accept that this would lead to power problems with the Reeds at the top end of the revs range. But since the 24/7 system does not use reeds for Intake at the top end of the revs only really at the bottom end of the revs. I was just wondering whether this could be taken advantage of to 'boost' the Bottom end power of the system?
A interesting idea Husaberg but I think like a lot of people 'Life' is getting in the way of the interesting things at the minute. It would be a interesting to experiment with the 24/7 system when I get the opportunity.

*I don't know if that means thinner or less harder reed material. Probably a combination of the two.

" I don't know if that means thinner or less harder reed material. Probably a combination of the two ".
Thinner is usually softer , but weave orientation is just as important , as you can construct a thinner petal that is stiffer due to the weave direction.
And of course the backups are a whole can of worms in their own right - creating multiple stiffness regimes dependent upon tip lift.

I have been midnight dreaming as well , thinking a soft petal could be arranged in such a way that when a preset lift is exceeded , the reed flips some yet to be determined clamp mechanism, over center.
Then the petal sits at full lift, a one shot device - but once past the finish line , who cares what happens next.

Bubba Shobert, and well there's a heap more but yeah, always best to pay attention after the finish line.

i was trying to remember whose bike hit Magee's bike, it still makes me feel queasy.

Sorry i thought he had posted it on Pitlane i have lost my password and couldn't be assed looking.
