An year ago i was already tired of building my project bike - 1985 GPZ900 which i bought as non runner. So i wanted a bike that is ready to ride when i have some spare time.
However, as you may expect, my inner voice was stronger then my rational thinking, so the mods started.

I bought the bike in mint condition with Titanium exhaust, BMC filter and ugly Chinese levers as nonstandard parts.



Some googling and reading and it all began.......

First mods that i did were the usual ones
- upgraded cables
- fireblade side stand
- falco brake lines as i wanted to move the clip ons over the yoke
- new K&N air filter as the BMC has started to fall apart

 After the bike was prepared for riding, i did a trackdayCool



I am a slow rider will very few miles on bike last 5 years, but i was very pleases how easy to ride  was the Mille. I was was turning easy, breaking hard and very linear on acceleration, plus the pseudo slipper clutch that kept the back wheel from chatter on downshifts.
I have done trackdays on that track in the past and  one of the times it was again with V-twin(vtr1000f), but it was way harder to ride as it felt heavy and like train not willing to turn.
Last time i was on the track was 3 years ago with 250 2 stroke supermoto and i did similar time on the Mille which on such small and slow track means to me that the Mille is very easy to turn even by an amateur like me. When i was riding the Supermoto i was catching all the sport bike riders in the turns(slow group of course), while now with the Mille i was keeping up with a supermoto guy on the turns and  was actually little faster, so again vary pleased with choosing the Mille as bike to ride.

With the bike on "sport mode" it was time to get on the track again, but since the was nothing more to be expected from the Mille, the was a lot to be done on my riding skills, so i went to "school" let by a local racer.



He helped me a lot on the race lines as before i was pretty lost on the turns.

thanks!
Unfortunately, cannot tell much on the riding as i have very little time to ride - since i bought the bike in last Feb have done 1,500km. But i plan to do more kilometers this year - if not on the road, then form sure on the track.

After i was pleased with the capabilities of the Mille and got some knowledge on the lines,
it was much more obvious that it is me that is holding the bike to go fast and follow the race line, so
it was time for another riding skills lesson.
This time i went to another trainer and started from the basics - turning and body position.
After one day of doing 8s i was looking like that in the end.


I was exhausted and barely walking, but it was worth it!
For that day, i learned a lot more than 15+ years riding a bike and countless hours watching Youtube videos, so if anyone is in doubt - go on riding school, it is the BEST MOD EVER!

At the end, what was stopping me for progressing more(except the exhaustion) was the tires and the clip ons - i bought the Mille with Bridgestone Blattax BT16, but the trainer advised i need semi slicks and the high clip ons over the yoke was messing with my body position.
So my homework was to get descent tires and get the clip ons back at stock position.

I did the riding school in September and unfortunately, since then i haven't had any chance to ride due to weather or lack of time, so i was focused on finding tires and doing mods Evil Smile

I found some supercorsas on ebay which i have not put on. The rear is 190/60, so i have some doubts if it will fit without any issues, but we will see.

One more thing that i forgot - i was sitting to close to the tank when training, so i ducttaped and old knee slider to the tank to keep me little back. To make this more "pro" looking i bought some racing seat foam to make a tank pad.


here is the knee slider set up


and the foam pad + some tank grip as the one i had before were not really working

Then some cutting to get it to shape



And since i was focusing on the grip, i added some grippier pegs too

Forgot to mention, that after the first track day, where i was smoked by every 600 on the straight,
i put the FR100 in. Now i understand that they passed my mainly because my bad corner exit speed, but little more grunt it always welcomed. Not sure if the bike is lot faster with it, but for sure the power is more linear and smooth.

The 190/60 will fit but you will probably need a longer chain as it will be getting close to the rear of the swingarm, I run 180/60 on mine and it just slightly touches the chain and it’s a 520 chain.

I bought the bike with 520 conversion and 16/44 gearing.
Is yours 180/60 Supercorsa or it is another make? As far as i searched, the different manufacturers have difference in the real width of the tire.

Super corsa, the chain just nicks the edge of the tyre.

With bad weather,  no time to ride and working all day on computer you have all the ingredients to be looking for more mods and upgrades.
Next on the list was open air box!
My idea was to get the rubber seal from the AP Workshops and use the top of my airbox for two reasons - first to save money and second to keep my new K&N filter as if i go for the complete kit i would need also the taller filter with the closed top.
I bough cheap second air box so i could play with it at home without messing with the bike.
With almost no tools i was able to do this se up.

With the open box still not installed, i came across a post in fb about i guy that made 3d printed double stack on Gen 2 using a 3d file for Gen 1 as a base.

i found the 3d model got eh gen 1 and started searching for someone to print it
here is the link
https://www.thingiverse.com/thing:3742217


A couple of local companies were asking 50-100 EURO to print it, which was too much for me to risk. A friend with Mille who has a 3d printer was going to print it, but he had issues with the printer....but then i found  a guy in FB who is starting a business and was doing 3d prints cheap.
He printed it for about 15 EURO including the delivery cost Clap


Here is the result




I am not familiar with the 3d printing, but as far as i understood he is printing it using some kind of resin. He had available at the moment just this grey one with is quite hard, but more fragile and not so resistant to heat, but told me that he has some black resin that is more flexible and resistant to heat.

When drilling the holes for the screws that attach the stacks, there were some small parts that broke of the mounting points, but not so bad. So i ordered the stacks with the black resin too.

The black resin stacks were not perfect and came quite bent because of bad packaging, but with some twisting and hairdrier heat they were usable. The black resin is a lot more flexible and i was not scared that the will brake to parts and some will enter the engine.

With the airbox seal and the stacks ready, i was doing final checks before putting the set up on the bike, then i noticed that i cut the top part of the box too much and it flexes when i try to tighten the seal and the seal can move which can cause air leak..... i had to find better ring to keep the seal in please.
I first bought a sheet of aluminum and started fabricating my onw ring, but as i mentioned i have very few tools, so it was quite hard and i did not wanted to pun something that ugly on the bike.
I searched the ebay in after a week i find this ring for reasonable price
 



Looking at the ring profile, it was not original intended for open air box, but to be used as spacer between top and bottom parts of the box and in this was increasing the volume. However it did the job to keep the seal in place.
Now i had to find a way to keep the filter in place and cover the top of it.
I cut a round piece from the air box for the top of the filter and the plan was to keep it in place using safety wire....at least as temporary solution to be able to install the set up on the bike.

A hour or so with the bike, the set up was looking like that.




Not the prettiest filter cover, but it was keeping the filter in place.
Bike starter with no issues and sounded ok. Cannot tell if it was revving better, faster or worse, but i did not saw any issues.
The weather is cold and i was not able to try it, just did a spin in the underground parking where i am keeping it.

I know the wire holding the filter is looking bad and reminds of this



But at that time i was not able to think of something better, which actually happened a week after while my wife gave me a clothes hanger from the dry cleaning shop and told me to trow it away....then this came up in my mindStar


I did not throw the clothes hanger away, but used its thicker wire and make this "bracket" - looks better  and cleaner set up at least for me.

I know that most of the people do the open airbox mod in combination with collector mod and put FR200 emprom in, but i was not sure if i will be ok with open airbox and FR100 or i should go for FR200. I asked Griff and also the guy that sells the Forza eproms on ebay and both advised FR100.
The Forza guy added that i should consider the collector mod and fr200 in the future(which i actually had in mind), because i will not be getting the correct fuel.
Some time ago, in parallel with the other mods, i was thinking about the AF modulators - those gadgets that connect to the air temp sensor and make the ECU think that the air is colder and in this was make the fueling richer. I got one such AFM cheap on ebay, but it was removed from Yamaha MT.
With some googling, i saw that the air temps sensors are not the same, but they have pretty similar output, so i decided to make some custom wiring and get it on the Mille. And now, with the open airbox and  more air into the engine, it was the time to put the AFM.

I cut the wires to the Air sensor and put waterproof connectors, then put another set of the same connectors on the AFM, so that if something on it fails, i can just unplug it.



Again, i was not able to do a test ride due to weather, but setting it at 5(as advised in the AFM instructions) may be made the bike idle cleaner or it was just a placebo.

Interesting Clap
 
Although I've always wondered if the best way forward was to fit a spacer between both airbox halves to increase the volume and still keep the unit sealed as it will then stop hot air contaminating the incoming charge like with all these Evo / Renegade mods.

One mod very common on Suzuki twins is lifting the airbox at the front to increase the capacity under the tank to allow this Wink

The aluminum ring that i got is actually such spacer

I tried to measure the volume that is will increase, by putting it on flat surface and filled it with water and it was not much, about 400ml if i remember correctly, while with the open airbox there is much more space between the top half and the tank to fill with air.
Not sure about the hot air, since the seal should keep it on the engine side and only the air coming from the inlets should stay in the "box"
However, i am not aiming to have "perfect" set up squeezing the very last 0.1 hp possible, but to have linear usable power curve with good throttle response.

Sorry,that should have read "lifting the tank" not the airbox

Not as easy to do with our tanks though,given the stretching and deformation we can get in the headstock area. It was just a couple of ali spacers on the Sv but the top yoke had more clearance to start with

You will have air coming from the air ducts, but also air coming from the window between the frame and the tank.
