Hey guys I'm new on here, just thought Id share my project with you. I picked up a 2003 Cagiva Mito evoII 125 for $2500 last last year and took it for my first trackday. I managed to run only 4 seconds slower than my oldman on his R1, I figured I could crack the 2minute mark pretty easily with just a new set of tires (I was running old bald touring tyres that only passed scrutineering because the bloke was nice)

Then It occurred to me that If I could get the Mito to brake much harder, turn fast, accelerate more rapidly and hit a higher top speed that I could run with the big-boys in the fast group even with my novice skills So I had the motivation, all I needed was an excuse;



30minutes later while running a hot lap, I went around the outside of an 1198S at turn two, lent her over too far, dug the foot peg into the track and top a trip into the gravel at 150. ouch



Sounds to me like an excuse for a project. It had to be a 2T, The powerband is like a drug. So I decided to build a 2T supermono.

The aim of the bike was to build a bike for less than a 5 year old 600cc bike ($7000)



The bike needs to be able to round up a stock 600 on a big track like phillip island and I wanted to give a 1000cc bike a run for its money on a tighter track like Broadford. 2 weeks later when I could walk without looking like Id crapped my pants I started making phone calls and found a bloke in Newcastle who knew his 2Ts, he was referred to me by Steve from Two Stroke Shop.



So far during my daily ebay searches Iv found the following bits, at very cheap prices to keep the bike within budget.



KTM380 motor with an Electronic Power Valve (EPV) similar to that used on a late model 2Ts<BR>Motor has a Wiseco Piston,



custom shaped head,



cleaned up ports,



39mm PWM eliptical slide, shortened carb' with solendoid controlled power jets



Custom Two Stroke Institute Pipes,



and reworked exhaust ducts to mimic the last generation Aprilia 250 GP bikes

Also picked up an r6 radiator and goodridge clutch lines this week.



Here are some pics of the motor in the frame

IV SILENCED THE CRITICS, YOU CAN RUN A TWIN DISC APRILIA WHEEL WITH RS250 FORKS USING STANDARD MITO YOKES AND AXLE
Its a much better alternative to the heavily sprung ducati forks
all thats needed is .5mm copper sheet for the bottom yoke holes, 2x 5mm axle spacers, 2 calliper brackets
EASY!

This weekend I made the much anticipated 1000km journey to Newcastle to pay Lozza a visit a Two Stroke Institute (TSI).

Immagine inserita

Immagine inserita

took off from Melbourne airport at 10pm on the Thursday nite after being stranded on the runway for 2hrs. But as soon as I stepped of the plane into the nice warm weather I knew I was going to have a great weekend.

I spent the first night unpacking the boxes apon boxes of Ebay goodies I had dumped in Lozza’s PO box over the last 6 months, It was reminiscent of Christmas morning. I then took some time to learn about the latest and greatest it two stroke technologies; dual exhaust cylinders and reduced turbulence via tapered transfer ports.

But the best part of the nite was getting to fire up my new CRM250AR that I had stored at Lozzas place

I dragged myself out of bed first thing on Friday morning where we began to finish of the new TSI workshop by building benches installing machinery with a crane and carrying boxes of parts up onto the second floor where the parts inventory is being established.

Immagine inserita

This process took until Saturday morning to complete and then the fun stuff began!
On Saturday morning I began work on the fairings which involved drilling and fastening with dzus fasteners aswell as fitting the screen and mocking-up the seat unit.

Saturday-day we installed the lathe and then proceeded to make some front wheel spacers for a final front wheel fitting. But firstly we had to hoist the bike of the ground because the bike lifts were already occupied.

Saturday nite we went out for an Irish pub meal and drinks before returning to the shed until the early hours to produce some brake calliper mounting brackets.

We started with some masonite with a pencil, verniers and a digital protractor. On the second try we got is spot on. We then transferred the template onto 14mm think Aluminium plate.

Immagine inserita
Immagine inserita
To get to this stage we required the ban saw, milling machine, center punches, callipers, and the old faithful die grinder
These are now all but finished, they fit and hold the calliper as designed but need cleaning up on the mill to look “professional”

Immagine inserita

Immagine inserita
We then began to work on the rear wheel where a spacer and a calliper mount modification was found to be required, but sadly we did not get time to
finish this
Immagine inserita

Next on the to-do list was the chain alignment which was sorted rathe quickly with a laser alignment tool.
Sunday morning we got out of bed pretty early and went straight out to the shed, had a pretty nastly nights sleep on an airbed covered in fibreglass shards so I couldn’t wait to get out of bed.
We started by machining up the “top hats” out of phosphor bronze for the rear engine mounts.
While I designed and tested a DIY soda blaster for cleaning parts, after several attemps where I returned to the shed covered in white powered with a still dirty part I finally got it to work with great results.

Immagine inserita

In some sections where the bicarbonate soda was really flowing it almost produced a finish not to far from polished Ally.
Anyhow, back to the engine mounts...

These made the engine fit absolutely perfectly...

We then moved onto the front engine mounts,
The concept for these is as follows.
14mm billet Alluminium engine mount arms mount to the engines with a 12mm shaft and spacers, the engine mount is mounted to the frame with a single Hi-tensile bolt that acts as a pivot point, a second rubber mounted bolt acts as a dampener for limiting pivoting movements in the engine mounts.
This should reduce vibration greatly.

These mounts are still in the template stage and need to be finished in a similar fashion to the calliper mounts.
It was then time to down a beer and race to the airport to catch my Sunday night flight back home to Melbourne.
How 3 days went by so quickly I will never know.
Hopefully now that Lozzas shed is complete, we can progress even further over the new year and with a bit of luck get her fired up on the next visit

there are all the promises for a beautyfull special
very great engine but personally the fairing does not, absolutely not, convince me
...100kg? mmm.. are you sure? you can't reach this goal with the parts you have listed and that i've seen in pictures

Apogies for not writting in italian, there was too much text and photos, it would have taken me hours to do it in italian aswell
The bike will be 100kg's because the Ktm engine is much much lighter and smaller than the mito engine!
we put the bike and all the parts on the scales and it wieghed 105kgs, close enough to 100kgs :Risata rotante:
just wait untill I have enough money for a set of BST wheels! one day!


Apogies per non scrittura in italiano, c'era troppo testo e foto, mi avrebbe preso ore di tempo per farlo in italiano come pure
La moto verrà 100kg, perché il motore KTM è molto molto più leggero e più piccolo del motore mito!
abbiamo messo la moto e tutte le parti sulla bilancia e si wieghed 105kgs, abbastanza vicino a 100kgs: D
aspetta solo che hanno abbastanza soldi per un set di cerchi BST! un giorno!

Airfairs booked for the 10th of march :Hmm:

Should get alot of the little bits and peices done

build the bottom end of engine, build some new engine mounts, subframes, mount the fairings, and do the spacers and brackets for the rear wheel and brake, and some other little bits and peices

Then all we need to do to finish the bike is modify the top end of the motor, electrics, paint, dyno tune

Had some trouble trying to get through airport security with a few kilos of CRM250 cylinder in my carry on baggage, but after putting it through the scanner a few times and giving me funny looks, they finally let me through!

had some dramas with getting the old roller bearing out of the cases. tried the 3 bearing pullers that we had and bought a new one then modified it on the lathe and still couldnt get it out. local ktm dealer was too busy to help us out on the day so we had to potpone the engine rebuild.
we ended up loosing a half days worth of work on this, and it also meant that we couldnt complete a few other major jobs that we had planned.

new engine porting and pipe has been developed based on jan thiels rsa250 research and development. this should increase the power output the 85hp+ at the engine at 8500 rpm. Started porting the ktm cylinder. its looking great but is very different to you'd think was a 'fast' cylinder. its very odd. but It works

still needs some more work, but its not far off

Overall we didnt get nearly as much done as we would have like to, but what can you do... sh*t happens (fukin bearings)
but instead we managed to get some of the 1,000,000 small jobs out of the way which are the real time consumer at the end of a project



Got the cases and crank back from KTM today, the old ones are removed and the new bearings are in.
also ordered my REDBULL decal/sticker kit :D

I did originally post up pics of the cylinder, but out of respect for Jan thiel and Lozza I removed the pictures of the cylinder which promises to make 80hp at the rear wheel now :biggrinthumb: It is a very odd looking cylinder, you wouldnt imagine that it'd be fast by looking at it.

platforms?

do you mean the foot pegs?

Those are not finished, just roughly in place so that we can build the pipe around the foot pegs
