Title: Air box mod
Post by: Chris Canning on May 08, 2005, 07:46:29 PM
A couple of years ago read an article,translated from a Dutch mag about removeing the blanking plate that is inside the airbox,tried to unscrew the two halfs and sure enough the screw picks up in the brass furrell and you can't get the dam thing in or out!!!.



Forgot all about it untill recently,when i bought a secondhand airbox of e-bay and finally got round to doing it yesterday,tank and air box is a straightforward job,getting the blanking plate out was a complete pain(Dremmeled it out) but got there in the end and had it all back together in a couple of hours.



Started the bike up,induction sounded exaclty the same but the motor certainley pickup much quicker,took the bike out for a run seemed about the same when first started of untill i got to the 80 mark where to say things came with a rush was putting it politely,bareing in mind the bike is pulling a 19 tooth engine sprocket and there was also a marked improvement with the midrange torque.



Before i'm completely happy i need to get a gas sensor stuck in the exhuast to make sure that the Lamba sensor can handel the extra air,but at the moment seems a major improvement.

Chris,  It just so happens I have my airbox out and posted a question about sealing around the idle motor.  Could you help me out?

Did you also remove the snorkel?

Blimey i was looking for this thread the other week and couldn't find it!!



Sorry Charlie i didn't reply!!,



And no i didn't remove the snorkel,thought i was asking for trouble with the possibility of water getting in.



I've some serious miles since the mod,a lot at high speed,and it's proved be an excellent mod,getting the blanking plate out and makeing sure you've all the plastic swarf out was the biggest hassle.

Thanks! The water issue is what I was concerned about because I noticed that if the snorkel was removed it left a direct opening just above the radiator for rain, bugs and smaller motorcycles :lol:

I removed the snorkel, enlarged the hole to the size of my fist and added another hole just as large on the other side (in additon to cutting out the blanking plate like Chris described).



Never had any issues with watter, rain or bugs... at least not with the engine... I do have a distinct change in sound as the motor revs up. I want to say I have more power, but I can't be sure without a dyno run... It would be nice if I could get the EFI re-mapped to work with the modified air box. Now that would really make a difference!

Race tune with an open Remus can,but any can will do!! so long as it lets the engine breath.

I would say it is easiest to unscrew the box and pull it apart, rather than try and dremel tool a hole in the plate.  I started putting holes in the top of the plate, and it would have worked too, but it took too long to drill, and I think i remember one of our UK members saying that he binned it ( trashed ).  So mine is out.. I kept the plate, just in case..  But I really hope the snorkels keep the water out when it rains..

Post by: Chris Canning on May 19, 2012, 07:34:31 AM
If you managed to get yours apart then your lucky,when the box's are made they ping the thread,I ended up with screws half out and the furrell turning in the other half,so it wouldn't come out and you couldn't screw it back in,hence why I said going the long route with a dremmel,it's a pain and messy,but it'll also mean's not having to buy another airbox!!!

Re the snorkel,I see some have taken there's off,we've ridden in too much bad weather to ever risk that,with it on everthing fine.

** A TIP from ATOKAD**

I used a 2 in wide wood chisel and after 2 hits with it and hammer horizontally and another 2 hits with it vertically, 2 above the internal venturis and 2 to the side of them, 5 minutes later after using a pair of channel locks pulling out the pieces, I was DONE!  Easy.

Could use a hot knife or a soldering iron, its a very steady job but it works with a lot less swarf.
To make a real peach of a job is to get another snorkel and drill the opposite side to fit, although the snorkel is oval it will fit. The alternative is to get an earlier airbox with 2 snorkels but this will have a metal baffle. As far as I can work out the off road tune will cope as quite rich anyway, but if any problems occur richen up with LTFT about a factor of 0:8.

Hi All,

I hope it's okay to resurrect this old thread but it's one I've returned to many times and now I can finally contribute something.

I did my airbox this morning with... erm... mixed results.  Blog post (and movie!) here:

Hi Chris,

Yep, I think you might be right. I have limited tools and nowhere to work. The bike is on the pavement outside our building and I did the mod on our dining room table. I thought splitting the box would make least mess.

Nice one Dave  :thumbsup

When fitting the Scottoiler, have a read of my old post about my throttle jamming open  :bug_eye

The PO fitted the vacuum takeoff in the IACV tube next to the throttle linkage.  First time I opened the throttle full it clicked over the T piece and wouldn't close again.  Frightened the  :Topes out of me.
Title: Re: Air box mod
Post by: Brother Number One on April 20, 2015, 07:49:48 PM
Aha. Wish I'd read that before I put the new bit on, yesterday. I'll be in there again before long, mind, as the stepper motor grommet was looking a bit tired. Cheers Bob.

Dave
Title: Re: Air box mod
Post by: Bixxer Bob on April 26, 2015, 11:29:54 AM
The plastics on these old bikes are prone to distorting; my IACV gasket wasn't sealing with the airbox so I added a second one using the original as a template and some closed-cell foam sheet.
Title: Re: Air box mod
Post by: atokad on April 28, 2015, 10:23:16 PM
I want my stock airbox back.  When I removed the blanking plate I also went to a 19T CS. I like the reduction in RPMs at speed but missed the torque by changing the CS.

Also noticed the MPG dropped from a consistent 48 to about 44. Note, I run all the time at 5500' and above for altitude.  Well I went back to an 18T CS (feels like a new bike!   :wheel) and now my MPG seems to be 40-44.

I am attributing it to the airbox but maybe I am wrong and there is something else I need to check?? I have the Triumph race can and the offroad tune.  New airbox in US $$ is way too high.

So trade?? Anyone?? Or maybe I need to check some air sensor, TB balance??
Title: Re: Air box mod
Post by: Bixxer Bob on April 28, 2015, 11:41:19 PM
I get around 45 mpg but bear in mind that's UK gallons with the 19T and airbox mod.  45 US = 38 UK if the miles are the same length...

Your drop could be your twist-happy wrist since going back to 18T, or it could be the airbox, or it could be the ECU needs to trim itself back to account for the reduced load of the 18T.  Give it a while and see if it settles down.

There's never a wrong time to balance the TBs........
Title: Re: Air box mod
Post by: metalguru on April 29, 2015, 12:16:19 PM
Agree with BB here with the throttle happy and raised revs.
The altitude shouldn't make that much difference to the off road map, the Long Term Fuel Trim however, try knocking it back by a factor of 0.8 and see what happens, its a bit like the main jet in a carb, the difference can be heard at idle when the idle trim is set to zero, knock the LTFT down till faltering occurs and raise until smooth running is achieved. Without a gas analyser and a rolling road this is the closest one can get. A definite figure for the settings on these bikes is unavailable as every bike is unique and has to be set up so.
Title: Re: Air box mod
Post by: atokad on April 29, 2015, 11:05:40 PM
Not sure how to adjust the LTFT.  Is that with the TB balancing or with the Tune device, neither or which I have or have had the need for.  The bike is almost at 30k miles though so I suspect I will need those items soon.

I don't think it's the wrist, as I used to get 48 consistently with the stock setup and have always done a fair amount of wrist twisting!  :wheel  The only think that is now different from stock is the airbox.
Title: Re: Air box mod
Post by: metalguru on April 30, 2015, 01:13:43 AM
It is possible with your set up that the mixture will need 'tailoring' to suit.
At 30k it is advisable to balance the throttle bodies and set the tolerances to suit the tune.
If you have not felt the need to use TuneEcu for this purpose then perhaps your friendly dealer could furnish you with the work.
Best to check the Idle Air Pipes too while the tank is off.     :thumbsup
Title: Re: Air box mod
Post by: Chris Canning on May 06, 2015, 06:00:47 PM
What I lost in low end with a 19t sprocket I gained with the airbox mod just means it just everything the same as stock with a higher top end just less revs what mine does to the gallon?? not a clue low 40's maybe? my idea of wringing the neck out of a Tiger has never tallied with any other that's for sure and I have never got much more than that with any of them.

The problem being the tiger was built years ago modern day motoring has moved on it's not about bikes per se it's about all road users with the advent that every man and his dog is driving a 200hp diesel car a stock geared Tiger now means your having revs the nuts off it to keep up never mind stay in front.
Title: Re: Air box mod
Post by: pxm on December 05, 2015, 06:27:25 PM
I've just done this mod but haven't gone for a test ride yet.
I removed the restriction using a chisel and mallet and it only took 15 mins.
The hardest part was getting the front tank bolt back in.

Actually, I have to remove it all again as I forgot to check the airbox is fitted under the lug at the front. It went back in OK so is it likely to be sitting above the lug?
I'd rather not have to remove tank and airbox if I don't have to.

Thank you to Chris for suggesting this mod. I'm looking forward to some more umph!
Title: Re: Air box mod
Post by: trophydave on December 05, 2015, 10:51:24 PM
Is it worth doing the airbox mod if you run a stock bike with standard end can and map?.
Title: Re: Air box mod
Post by: Chris Canning on December 06, 2015, 11:51:39 AM
Honest answer!! No idea  :icon_scratch:

For me the whole concept was to have a mod that masked the extra tooth on the engine sprocket,but in your situation there's only one way to find out :icon_wink:

If it was map or can,I'd take the can,in fact for some years that's the situation I was in but didn't realise it but that's another story :icon_redface:
Title: Re: Air box mod
Post by: fattyjr on December 06, 2015, 05:51:13 PM
Well I just ripped out the steel divider in my stock airbox and what a barstool that was.  I was going to try splitting the box but first screw I tried to undo spun so left them.

I think there is a better response (with stock map) but i flashed in the TOR map so will find out tomorrow on way to work.
Title: Re: Air box mod
Post by: Bixxer Bob on December 06, 2015, 08:19:22 PM
If it wasn't seated corectly you'd never get the tank back on.  Front lug not lining up is very common if the tank has been off for more than a few hours.  They don't like being left sitting around, especially with fuel in them.
Title: Re: Air box mod
Post by: fattyjr on December 07, 2015, 07:25:41 PM
first ride with the airbox mod and you can tell the intake makes a growly noise when you open it up now.  It was quite a surprise as you don't hear it when it's at idle.

I would say seat of the pants dyno says yes. I got the exhaust to play with now, but cant make my mind up on a single or duals or even a reverse cone like I have on my sprint. I have a sound clip of my sprint.

As it finally stopped raining, I took my Tiger for a ride today.  First time since I'd removed the airbox baffle.
I could certainly hear more intake roar, which I don't have a problem with.  I haven't been using earplugs since fitting the Palmer screen as it's so much quieter.
It seems to take off well, but I'm not used to the increased power liberated when I took a big bar to my exhaust baffles & remapped the ECU for off road tune so it's hard to say if it was even more powerful than before.
Anyway, illegal to much more illegal speeds come up very fast, even in 6th gear.
I'm very happy with the mods I discovered on this site.  Apart from the inevitable drop in mpg as I'm caning it more, everything is good!   :wheel

not sure what the sprocket size is on mine, but the old tiger will happily lift up the front wheel (abit a little) and I have had the rear wheel break loose a few times since the mods.

Next plan is exhaust mods to ditch the pancake under the bike and the horrible can.
Title: Re: Air box mod
Post by: Chris Canning on December 31, 2015, 12:08:20 PM
The whole idea of the 955 airbox mod was to pep the performance up so you could put another tooth on the gearbox and get the exact same performance for 500 revs less,although when you do start to stretch its legs there's a marked difference on the upper reaches of the performance as well.

I'm still on stock tooth sprockets.  Mind you, at 19k miles it's about ready for a new set of sprockets & chain.
I don't have a chain splitter so I've avoided replacing it so far.
Where's the best place in the UK to get a 19T front, standard rear & new chain Bob?
Title: Re: Air box mod
Post by: Bixxer Bob on February 29, 2016, 01:42:16 PM
I use DID, which needs it's own brand chain splitter / rivetter so you might want to go for another brand.  I got my last set from Demon Tweeks of all places as they were cheapest. Which has never happened before.

Just search Ebay and go for the cheapest known brand but avoid anything you don't recognise.

I've done that Bob, but I'll just end up with a standard front sprocket instead of 1 tooth more.  There isn't the option of specifying how many teeth on any site I've visited.

And funnily enough when I was looking the other week, Demon Tweeks were still about the cheapest online. I went with a shop in Bristol in the end as he did a price match. JTF1180-19 is the front sprocket p/no, and yeah, DID or maybe AFAM, but I wouldnt touch EK or similar. JT now do there own range of chains but no real reports on them yet though the guy in Bristol sells loads and hasnt heard anything bad. Personally Id still go DID, you can now buy a DID copy chain tool for about £30, Ive got one and it works fine, just dont try pushing the old pins out without grinding the heads off first

So it's probably worth me buying a DID chain kit from M&P for £80 or so, getting a £20 19 tooth front sprocket, binning the 18 tooth one that comes with the kit & getting a mate who has a splitter to help me fit it.  It works out cheaper than paying £140 for a kit where I can specify the front sprocket size.
Can anyone see a problem with this idea?  :^_^
Title: Re: Air box mod
Post by: HockleyBoy on March 01, 2016, 02:34:37 PM
None at all but I think the chain from Squaredeals is an upgrade to the one than the M&P so you are not comparing like for like.

Personally I have just fitted a £90 DID chain and sprockets and they are fine.
