Heh Great job Jeram. I see in your work a lot of passion that's very cool. Please tell me how old are you? AND WHERE THE HELL YOU HAVE THE MONEY FOR IT ALL PARTS!? xd

Im 23, final year civil engineering student.

to describe my income as an analogy... Im running on fumes haha

but the projects have cost me alot less than you would think

The KTMito380 project owes me less that what it would cost to buy a brand new mito 525sp or a 2005 Yamaha R6.

the CRM250SM project owes me alot less, perhaps half the cost of the mito.

Alot of money was saved by being patient and waiting for bargains to pop up on ebay, I also made some money selling parts from bikes that I didnt need, but most of all the work that I need to get done by the professionals is often discounted or free because they are usually friends.

with the project I guess I wanted to prove that you could build a fast, unique bike without spending a fortune.




MORE PROGRESS TO COME ONCE I FINISH MY EXAMS!

[fede89]

omg

[Jeram]

I found a MITO 525SP PISTA subframe and seat unit on ebay last week and had to buy it before someone else did!






that is a very sexy rear end!... reminds me of a cross between a Cagiva 594GP and a Ducati Desmo.


I should have it in about 2 weeks and then I can fit it when I next travel up to nextcastle in December.

things to do on next visit
-mount the subframe and seat
-mount the shock
-get the rear wheel and brake fitted properly and fit an old tyre so the bike can roll around the garage
-get the engine mounts CNC'd
-make a new pipe design from cardboard and then send off to the laser cutter.

oh and got the front brake brackets made ages ago but forgot to post up

[motoracer15]

a quanto pare non sono stato l'unico ad avere l'idea di trapiantare il motore KTM380...... peccato che ho la moto intera e devo poi lasciarla senza motore -.-'
ma se riesco a trovare un motore 300 per la mia enduro, questo supermono sarà il mio prossimo progetto!

don' t use 8.8 bolts for mount brake calipers and brake disks! Is dangerous! use at least 10.9, or 12.9

[Jeram]

No 8.8's are used anywhere on the bike. They are all a minimum of 12.9.
Even though most people like to say 10.8 and 12.9 are the ONLY safe bolts to use, I believe that If I did the calculations we would find that 8.8 grade 10mm bolts are more than fine to use.
From doing bolt shear calcs last year for 6 months I was surprised to find the small difference in shear capacity between the grades of bolts,
However yes you are right, there is nothing wrong with using the best available! and that is what I usually do when cost isnt a huge factor.



These 8.8's are just two bolts I had lieing around that I used to keep everything bolted together so nothing was lost.

Bike has progressed recently, and I will be working on the bike for 5 days straight at the end of the month

we're hoping to start the KTMito engine for the first time in just 2 weeks.


That means we have to work very fast to build the pipe, refabricate the engine mounts that I redesigned last week, wire the bike up and finish the engine off. Shouldnt be too hard as weve had a very long time to contemplate and plan this

high output stator and flywheel that I had made




plumbing is organised




had a CNC radiator filler cap made




and got a gear shift lever for the first ride, will likely cut it up and connect it to the mito gear leave/linkages




we are also experimenting with a 300 gram battery

[Jeram]

heres what we got up to this weekend

All in all it was a pretty productive weekend but a few setbacks stopped us from getting the bike fired up.
1. putting the 'bling' orange clutch master cap on removed the magura cap which warned not to use brake fluid.
brake fluid was accidentally placed in the MC which ruined the seals preventing any hope of starting the bike.

2.Dropped the cluch shaft double needle roller on the floor, losing several rollers.
couldnt find an exact match so had to machine a couple new rollers from similar rollers.

3. my ankle exploded on the 3rd day, swelled up like a balloon and I could barely walk for the remainder of the trip...

so yeah, considering the above I think we did pretty damn good



First off we finished the front brake system by installing the 19mm forged master cylinder, connecting the braided lines, and installing high tensile bolts/washers on the callipers
Most insanely powerful brakes Iv ever felt, true one finger racing braking



engine cases were again split open to investigate a gearbox issue, turned out to be the shift forks/drum had derailed

Luckily an engine removal is quick and easy, four bolts to swing the engine down for quick/easy top end work and slide the swingarm pivot half way out to drop the whoe engine.



Im happy to report that my new engine mounts look like they will work amazingly.
They are super firm but have a surprising amount of dampening flex when required.

It consists of a bar which runs through the front mount of the engine cases, this bar connects to an aluminium mount on either side of the engine which then passes all forces and vibrations through half inch bolts and into the four independant dampeners before tranfering the loads to the frame rails.

here is a picture from earlier in the weekend before finished


POST 2/3

chain installed and aligned with a laser... is absolutely spot on!



engine back in the frame, and bodywork installed so that the expansion chamber could begin being fabricated.




Minimalist cockpit/dash area. just needs to have the micro LED tacho installed


Nitron shock installed


I really like the look of the slick, the race tail/tray and the nitron race shock...
gives me an ear to ear grin just looking at it


just some more pictures



POST 3/3


really reminds me of the Cgiva GP593/594 from this angle


couldnt find the OEM intake boot so begun fabricating one from alluminium.
didnt quite get it finished but it is a short/straight intake boot with a tapering ID, from 41.5 round at the carb to almost 60mm rectangle at the mouth of the Vforce-2 reed block


And a quick walkaround video of the bike





Major things to do now before bike can be taken for a ride:
-Finish the Exhaust
-Rear brake

after seeing that there is plenty of clearance with the 4.25 rim and a 160 slick we are not looking at fitting a 5.5 inch ducati 999 rear wheel with a 165/17 250GP slick.

[{mRk}]

A really good job, congratulations!

[Jeram]

Correction... We ARE looking at fitting the 5.5 inch Ducati 999 rim.

Anyone used a 5.5 rim yet?

[{mRk}]

I used the 4.5

[TheStig22]

any updates?

[Jeram]

yes, we hope to have the bike started in 3 weeks, I have purchased my flights and will be working on the bike for 5days (8-12 th August)

just need to finish the pipe, quickly wire the bike up, and plumb the coolant lines.

then we will start it up!

[mitistomane]

great job,man!

[Jeram]

Ok, so heres the latest build report from the weekend.

First things first I quickly plumbed the bike, using the Two Stroke Shop bypass thermostat, the stock radiator, a T peice and bought a ton of radiator hoses from the local auto shop which had plenty of bends in them to use.

It all went together pretty well without any issues, just need to protect the rad hose above the exhaust header with some heat wrap.




Once that was done I moved onto the gear linkages, we put a KTM380 lever on the mill and made it into a sportbike still linkage lever, added a few rose joints, a DYNA quick shifter unit and a linkage rod.
done and shifts through all gears cleanly.



did a bit more work on the engine mounts, they just need a couple simple crush spacers made for them now, 99% complete



the cases were also ground down to accept the trail teck y2k stator and heavy flywheel. the stator cover will be left off the bike to allow it to fit.


We then moved onto the main event. The expansion chamber which we've dubbed "the Anaconda"

After 3 long days we got 3/4 of the pipe done. Lots of template making, cardboard mockups, tin sniping, grinding, tack welding and circumfrence welding!











the belly segment has 400mm of welding in it alone.



heres why its called the anaconda, can fit how many fists into its belly?




sitting back on sunday evening admiring our handy work so far.






not much left to do now.

untill next time,
Jeram

[edo9334]

Wow great job man!!

[Jeram]

just finished ordering the last of the pieces we need to start the bike up.

few little engine plugs and covers, a few circlips, spark plugs, soundproofing foam to make a dash out of and some very small alluminium tube to make fairing mounts with.

The silencer has also been modified to look a little more 'GP' with a downward facing spout.

we have also found a new two stroke premix that I will be testing out, it is a ceramic/castor blend.

[edo9334]

Some news? We want the anaconda completed!!!

[vespino91]

non ho capito niente ma dalle figure posso solo dire...
