Tomos forum

Hello

Greetings from Slovenia
First i mus say... nice forum you got here

Let me introduce you my project

It all started when i bought tomos BT 50N and then start restoring it :





now it is waiting


than i started engine tunning
at first... two boosts


and than... 4 boosts


exhaust is 190° transfer 130°

i also made a reed-valve take-in
step 1- welding


step 2- making hole



i already enlarged the hole, so the reed valve have enought space for opening


i still have to polish it

then i bought bigger carburator- dellorto PHBH28


then one day, i was bored, and i modified serial MF3



and i allready made a plan for custom exhaust

than there was another boring day and i decided to make a plan for 6 speed gearbox
.. but 6 is too few... so i decided to make it seven
but there was some problems becouse of one screw hole, and instead of replacing the whole screw location, i desided to make 6 speed gearbox, but with gears from 2 to 7



6th and 7th gear from the secondary transmission


i also had to modify "frame" of engine to fit it in. the distance from sprocket and alluminium is 0,4 mm



than i had to amplify clutch drum


the top ring is stil under construction

than i ordered better bearings for crankshaft
FAG NJ 203 ECP


i have ordered better big-end bearing -silver cage and more needles- for connecting rod too. But i didnt get it yet, becouse tey do not sell it in our country. So i have ordered it from your country- from EMOT.nl GOD BLESS NETHERLANDS

The crankshaft still needs to be build:


there is enought material for 4 excellent and one bad crankshaft

and a difference between tomos 80-90cc original connecting rod- the gray one and the one which is made in Serbia this days.


a few things have to be done, but i must wait to get all the bearings.
18 horsepowers is expected- by calculations
i spend 1100€till now, and next week i will give the cylinder to renewal-- new nikasil--- +100€


comments and critics welcome

Hmm, I've seen this Tomos already, on mopedist.si

yes
i read in your topic that you have forum too, so i decided to pay a visit

allright, atleast you've got an nice Tomos!
or actually you've only got nice parts

hehe
soon it will be tomos

Oehh like like like

The bt cilinders are fast

nice ideas

I have a Tomos NTX And a bt 50 cilinder And 17,5 mm carburator

Im gone buy a 21 mm carburater and 21 mm intake

Maby you have a 21 mm bing and 21 mm intake

Here below you can see my moped

i do not have bt cylinder. i have e90
that is 90ccm

and i allready saw your mopeds, and i like them a lot

Ha thnx on mopedist .si


I'm painting my moped when it's about 15 degrees outside.

I I have no idea which kind of color i'd paint it, do you have any suggestions?

metal-blue
for my opinion this is the best color for bt/atx/ntx models

hehe nice commercial

haha oke bleu metallic


there are more commercials

Nice

nice, i'm curious about how it is going to look when it's finished

update

i made holes for first two boosts (tomorow fine grinding)


and holes for second two boosts will be like that (quickly and approksimately drawed)

looks nice, how come you slovenians always seem so skilled in metal-crafting

hehe. everibody is
you just need some practice, and you get it throught the work you have done before

looks nice, how come you slovenians always seem so skilled in metal-crafting

Maybe that's why Tomos is from Slovenia

today i send cilynders, to restore


meanwhile Im waiting for parts for this project, im dealingl with this

25 kmh A35 cilinder... Im "putting" on tomos juniors portmapp.

Really an interesting project, and indeed I also wonder how come you guys always have all the tools and knowledge to tune far more better than us. Haha.

actually... i worked for two years through all holidays, to get the money for the all equipment i need.
and knowledge comes through practice... ( I m doing this kind of stuff for around 5 years )

Thanks for comments
