Depends I suppose Confused

That Suzuki mod was for airbox removal and two large individual throttle body mounted filter pods. All the standard air intake came via a small letterbox inlet behind the hot radiator so at least it could get some cold air.

On the Gen 1 Apes the air comes via the side scoops but then passes through the 'very hot in the summer' frame rails which is not good as although the std airbox is sealed it's fed on heated air. The Rene type mod which Micah S has proved is counter productive doesn't actually do anything unless you're just after intake roar that makes your ears bleed.

Given the intake limitations on the Gen1 I came to the unscientific conclusions that the best homemade way forward was more efficient air intakes in the nose ( heat and flare the sides out slightly into scoops) feeding into Edwards tubes. From inside the frame rails insert the cut off horns from the later restricted airboot which when relieved slightly will meet the Edwards tubes half way through the frame rails elimimating as much as possible heat soak. The inner cut ends can be modded to then fit inside the flared horns of the earlier unrestricted airboot complete.

That should give the best possible cold air path using std Aprilia parts up the the std sealed airbox. I then did what you did using the top of a spare airbox and cutting away the back half leaving the front with slotted windows to hold the filter down and also clamping a neoprene ring from the Evo mod to seal round the tank.

I intended to follow that up by replacing the airbox lid with a new top half complete but just with a metal spacer like you have ( ironbite?) between and then lifting the tank to give enough clearance for the newly enlarged sealed airbox.

I lost interest shortly after due to other things going on in my life and came to the conclusion that if I wanted more power I'd just get a newer,more efficient bike so that's where my old Mille still is today  Smile

So your thoughts are that not the volume, but the temperature is the issue?
I have some gold heat reflective tape, which i planned to use on the bottom part of the air box, but may use it on the frame rails if this will make any difference.

As stated, i am not after squeezing every last hp possible, but more on the normal operation of the engine and linear power delivery. I went for the open airbox, because i read that it fixes the midrange hole in the torque and i saw some dyno graphs showing it. May be they were with collector mod and the airbox itself does not make such big difference, but at the end i am after smooth working bike with no holes in the graph, even if i sacrifice hps or torque.

I think it's all a bit subjective,after all a bhp here or there isn't going to make as much difference as sitting on the toilet before a ride LOL

I do know that ic engines nearly always give more responsive power when fed cool,moist air and so that's what I put my efforts into going after. I've never bothered getting a dyno tune as I'd rather the geriatric engine lived it's twilight years in relative comfort.

Those frame rails get too hot to keep your hand on during the average uk summer? so without the Edwards tubes etc that's got to warm the air considerably I would have thought.

I do know that Micah S over on AF1 comprehensively rubbished the Rene setup on his dyno,how much of that was heat soak I don't know but I expect it would have some bearing.
Also I remember when Renegade was still going they dynoed lots of their systems after fitting and I'm pretty sure most of any visible gains were mainly down to the exhaust mods not the airbox delete.

The best bang per buck on a single can Mille is undoubtedly one of Mark Redratbike's modded collectors along with a modified eprom to take advantage of the benefits,I used a Forza chip but Gabro is possibly the goto man in Europe. All I can say is just swapping the collector and eprom without even resetting the throttle bodies made the bike feel like it suddenly had a bigger engine.

More grunt everywhere and I think it filled the midrange dip that I believe was engineered in by the factory to influence noise/emission regs testing.   I can't remember were I learned that little gem though,could have been in conversation with Micah,could have read it somewhere,but once it gets filled in the bike is so much better to ride.

If you haven't already either got a full twin can system or modded collector I can say with total conviction that's the first steps needed,anything afterwards is just frills round the edges in mho.

The collector mod is on my to-do list for sure - i was not able to get to it this winter, but hope to get it done on the next "winter modifications" period

Funny to mention it, because i had some time to "sat on the toilet" last eveningTongue





The plastic blocks that came with the battery turned out to be quite heavy compared to the battery so i put some foam instead - plastic blocks 91g vs foam 15g





Total saving compared to the normal battery
4.696kg - 0.857kg=3.839kg

Even with the OEM tool kit that i put in the rear(700g) it nets as very healthy number 2 in the toilet.Big smile

Few other times you can get an 82% weight reduction while also improving the function of the bike. I love how the lithium kicks the motor over and the weight reduction is a bonus.

You can reduce 3-4 kilos from full exhaust system or magnesium wheels, but both will put you back the price of the Mille Embarrassed
Adding on that, i got the Lithium battery for 50EURO on ebay auction.

Last Saturday was the bike season opening, so on Friday i took the Mille home(i keep it in the parking lot at the office) and left it outside for the night to be ready for the next day.
The temps here drop around 0'C over the night and i did not took the battery off - it is brand new battery, i thought it should be ok.

But on the next day, when i turned the key and checked the voltage on the dash, it was showing only 11.8V - on Friday, before i started it, it was showing 13V.
I did not risked to try to start it, but put the battery on charger while i was getting my riding gear on - 10-15mins. Then the voltage was 12v. The bike started as usual, even with 12v the starter was turning ok and 1-2 seconds after touching the starter button it fired up.
So now i am not sure if there is something wrong with the battery, or it was the cold that dropped the voltage or my be it is normal voltage for that battery. During the day i had no issues starting it.


Besides this  "issue", the bike was doing great!
I did not heart some noticeable increase in the noise from the open airbox or the stacks, but it was running smooth....god to go on the bike gathering.


After the bike show, i did a ride with a friend. Getting out of the city took 20-30mins and most of my muscles where already stiff when we hit the open road. The clip ons on the original position under the yoke were not so bad for my back and may be were making my head little lower and not so exposed on the wind. The roads were still cold and every bigger opening of the throttle was followed by wheel spin. However, near the end of the trip, the things were little better and i was more and more close to full throttle acceleration on the straights. I was very please with the power - turning the throttle at 4k, was making the bike pull like train, with constant acceleration up until 10k....no flat spots, not sudden hits. I was so pleased, that i am not sure that i need the collector mod, at least on the road i don't believe i can use more power on the mid range and it will just result in wheel spin, but with some decent tires on the track it may be good :)

One bad experience was the sound level from the exhaust - steady throttle getting out of the city and my right ear was already not hearing very well, keeping the bike between 4 and 8k on the twisties did not make the things better and my left ear got also bad.....end of the ride i was like getting out of the disco club 4am in the morning.....you hear constant noise in the ears.
On the next day, my hearing was still not 100% recovered, may be i need to get some ear plugs.


Second thing i noticed - the front was diving quite a lot when i was getting off throttle.
The bike has so much engine braking, that i was barely touching the brakes, but just roll off the throttle - with the cold road and the rear spinning, i was not confident in the front to push it and be hard on the brakes. Still, the front was diving quite a lot, upsetting the bike.
I guess it was not serviced long ago, i got some pictures from the previous owner with the forks apart, but the photo was taken from the owner before him, so it was not serviced at least in 3-4 years. Also there is thin oil film on the forks, which cannot be considered as leak, but with time i guess the level has dropped.
Other than that, the bike felt stable and solid. May be more stable then before, due to the forks now at 3 lines showing(before i had to move them 5 lines to be able to put the clip ons above) or
because of the oem steering damper, which i put.






Next things on the list - fork service and putting the supercorsas on.
For rear tire, i did some research, and it appear that it will hit the front of the swing arm and i will need longer chain to fit it. Also 190/60 will change the gearing and if i want to keep the current ratios, i need to go from 16 to 15 front sprocket.
There is 4 links piece of new chain i got from the previous owner, which i can add with two rivet links, but not sure if i want to go this way or save some money and buy a new longer chain.

This might seem like heresy but I'll put forward my opinion here that I think the Mill'es standard forks are only fit as a mounting for the wheels Shocked

As a suspension medium they stink as standard,far too harsh on compression and bugger all use in rebound,in fact I think the engineers just went to Showa and said ' what have you got on the shelf and cheap that we can have for a knockdown price.'

On the gearing front I run 15f and I think 44r, it's short but usable if motorways don't figure in your plans,this is with a 190/55 rear tyre.

Lithium batteries need " waking up " Which goes against everything we have always done with a lead acid. You need to turn the lights on for a few minutes and that should be enough. I have got a brand new Shido on my 675 and I was impatient leaving work after a night shift last week and it wouldn't start. Left it a little longer with the lights on and she started. It had been sat outside all night around 1 degree. Lithium batteries HATE the cold!!!
I started out with nothing and I've still got most of it left

May be you are right, but i am not at the skills level, where i can make a differenceEmbarrassed
But fresh oil is a must to have working suspension.
I have changed 6 months old fork oil on my ktm, with like 5-10 hours use and it was looking quite bad, so i can imagine how 3-4 years old oil looks like.

I am riding at 140-160kmh at the high way as average speed and i am not after more then 200 as top speed.

That reminds me...I've got a Millie in the garage that needs taxing and riding.
The slurry tankers were working on the farm this week so it can stay in the garage until next week.

Some updates...

I tried installing the Brembo 19x20 MC, but with no luck - it was hitting the dash badly even with the adjusting knob removed, so i went back to the OEM MC, which actually works pretty good.



I also went to my first trackday this year.
I do not have a trailer, so i had to ride to the track, but it did not started good, as my rear seat cowl fell just a couple of mines after i went off - i guess i have not locked it properly.
Unfortunately, the two of the mounts that keep the cowl and the base together broke off and i had to use some ductape to keep it in place.

I glued the mounts back together and added some silicone to be on the save side - it is not looking pretty, but i don't want to see the cowl flying again.


Next day i was on the track, with a target time of 1:25 for this year, after i was at 1:30 last time, but now i got a couple of riding lessons behind my back.




First session was a very badConfused....it felt like i have never been on the track and the time was even worse than last time. (best lap at 1:31)
Then i get my mind together and deiced for the next session to take it step by step, starting with running the right gear at each section and being close to the correct lines and it did worked!
After several laps, i looked at my mobile phone and i saw 1:26 as best lap - it was a very good surprise for me, but i wanted to keep myself focused and not do anything stupid. After the session i checked my RaceChrono app and i got 1:25.47 as best lapTongue - target achieved!

Third session - i was again trying to keep myself focused on the gears, lines and adding some corrections on my body position. However, i got into traffic most of the session, but near the end i passed through the pits to get some clear track in front me and my clocked 1:23.32 at the last lap.

In forth session i was pretty consistent at high 1:23s, with best lap at 1:23.18, so i was very happy for the day.
The temps are 33-34'C, so i want for lunch, the did a last session with very slow pace, then i had another 150km to get home.

Yesterday, i went to check the bike and if everything is ok with the double stack and they look good.
There was just some oil int the airbox, but i guess it is normal.




I also had time to install the Healtech quickshifter that i got some time ago.
It is iQSE-2, which is not the model they list for the Mille and their support stated that i should not try it as it will damage the ECU, but i connected it and i seem to work, at least at standstill - it was raining and i was not able to test it on the road.

Finally i got time to take the bike for tires change.
I bought JT 520 chain, as the wheel had to go back in the swingarm to make space for the tire.
But 190/60 Supercorsa did fit Big smile



The rear mudguard needed a couple of washer each side to have clearance with the tire, but it was not hard job to fix.





The bike is definitely higher in the rear now - i am 1.81 and i cannot step fully on the ground when sitting on the bike.

On the race bikes I always removed the rear hugger and lengthened the chains to accommodate a 60 profile should I choose. 
When it got hot it could start to rub in the swingarm on a standard length chain. 

Interesting on the healtech QS isn’t it.

I had the chance to test it on the way for the tires change and it seem that kill time on the crank is way different than the one on the coils, becuase i have set it at 90ms(to be on the save side, adn then to start reducing it), but it was way too much. The bike died in motion for 1-2 seconds and then went back on. However the bike did changed the gear without the clutch and with the throttle opened, so at least the shifter sensor is working ok.
There is Supplementary manual for installing this type of QS on SRAD advising that the kill time on the crank should be 40ms and not 80ms as on the coils, so next time i will start with 45 or 50 ms and then reduce for fine tuning.

Tried to test the QS again with 45ms kill time, but the bike died at a stop light and would not start before i turned off the QS from the app, so i will not deal with it anymore....

I did another riding lesson and trained changing gears with no clutch, but just off throttle when changing and it works pretty well - much faster and cleaner then using the clutch.

With the Supercorsas i was now able to push a little more and finally touch sliders several times.
The bike also turns in a lot faster with the 190/60 rear.
Stopping was also better and more confident then with road tires.



Forgot to mention that i put some Gilles last week :)

may be you did not read the previous posts.....

this one is not cutting the power to the coils, but interfere with the pick up from the crank
therefore the kill time is almost double - 40 at the crank is about 80 at the coils

however, there may be other issues with the sensor or noise filtering, so i will not spend time to try to make it work
