- 2nd installment: How to upgrade a TOMOS moped series. I secretly kidnapped my Dad's moped... to install a couple of upgrades. In the previous episode, we installed a performance exhaust pipe. We continue the process with an air box modification and a larger jet in the carburetor.
To get the most efficient power, we want to fix a ratio of 14.7:1 (air to fuel). In the stock configuration, this ratio is true. BUT, we can get more power and speed if we add more fuel. So, to maintain this perfect ratio, we must increase both air and fuel.

I can just se the sparks in your eyes when you are showing us those tomos sheets. It reminds me of when i was a kid and i was watching pictures of planes and imagining i flew one. I live here in slovenia, where tomos was created and its nice to see that someone so far away is having so much fun becouse of them. Unfortunately, tomos story ended sadly, but its still a nice heritage and we still have a lot of clubs here which organize meetings
Thanks Kristjan, i know i am not alone with appreciating these bikes. Lots of good memories.
How did it end?
@@ericsalidbar1693 tomos you mean? It went downhill after the fall of yugoslavia because motorbikes from other countries could be imported more cheaply and they were more advanced too. Tomos didn't really upgrade their bikes enough to stay competitive. In their last years they tried with a scooter, but it was too little to late. They also made a 125cc supermoto with yamaha engine which were pretty good, but they didn't make that many of them. Apart from that they kept making these 50cc automatics and apn6 (alpino, but basicly the same thing) which were basicly the same as the old ones and to most people scooters were just a nicer option. Personally i liked tomos stuff but i'm a bit old fashioned in that regard hah. So at the end they just stopped producing bikes, there is still some stuff going on in their facility but im not sure what exactly they are making there now and if it's even still called tomos, probably not i'd assume. In their top years tho tomos bikes were great and technologicly advanced, they also raced in some series but that was long time ago. So i think (could be wrong) that the main issue was that they stopped improving with time, because they could do that in socialist yugaslavia. But when capitalism hit them and the competition came, they were to far behind and unprepared to catch up.
Anyway this was all from the top of my head so feel free to google more, maybe some information is wrong and i surely missed a lot. I just know some stuff that my dad told me (he used to work there when he was young) and what i heard from news.
Glad you mentioned altitude. I live at 7500 feet & the first time I put a new pipe on my old Tomos I had a hell of a time figuring out what jet worked best. With a similar pipe on an a35 it four stroked like crazy with anything over a 64. Many days waiting for treats packages from San Francisco... I miss my Tomos!
Awesome treat for dad!
Hand held drills are difficult for sure.
i guess vise would be nice in that shop..
Killa miles😆. Mopeds with Dads is awesome!
Regards from a croatian Tomos rider!
You look like a good son. Greetings to your parents. They must be proud of you.
when dealing with a aircooled two stroke engine then 14,7 to 1 is to lean , more like 13 to 1 to be on the safe side
I watched episode one and then this vid.
You do very well at instructing how- to- mechanics.
I just got a Kinetic re-done ( puts a smile on my face), it is dog slow, (28mph) quiet and rides a bit stiff. I like the quiet though, so the expansion pipe is out.
There are so many idiots on muffler less cycles and fart pipe Hondas around NY, that the legislature passed a law to try to control them. ( Good luck). Mike
Thanks Mike! Best of luck with the Kinetic
im going to get my self a tomos A3 in october and im only 13 years old so this will help me alot in upgrading it cus its slow as heck when its stock really love your content now
Mom's right... get an effing helmet and jacket
XD Dad poppin' wheelies was the best!
My poor mother.
Have you seen Treatland TV party pack carburetor. Just got it but you have to pre mix the gas.
Interesting, most the research I’ve done on jetting a A55, they suggest a 58-62 main and change from 25 to 30 on smaller jet. Even changed the atomizer on one of my Tomos. You’re saying 70’s. I need to check the 2 I’ve done.
You have to do the airbox mod to run this jet. Definitely keep the 25 idle. The 30 tends to flood the motor at a long idle
@@MopedProblems ok, yeah on one I did the airbox mod and the other I got a angled K&N style. I went back to researching and now coming up with a 64 main with this set up. Stock with bi turbo and mesh filter. Some say 64-68. I thank you for replying and I’m definitely going to up the main, and go back to 25 idle beside it does load up when idling. Think I put a 210 atomizer in the first one, but this one I left it the original size. Have a great day and hope to see more from you soon!
You're the best Pete! Thankyou for my shirt! I love it and ot fits great!
we did this some 25-30 years ago (or even remove rear pipe entirely for some dirt action , lol). nice to see slovenian mopeds used by muricanos.
p.s. it should go or accelerate much faster than that, just rip it off.
Kilamiles i love it lol.
like the wind great move
Спасибо!
Would you recommend to do the same mods to an a35 airbox? and do you know if the a35 can be swapped out for a a55 airbox and still fit under the stock sidecover?
yogi bera: I use it every time I start it !
Wish you did before and after ride
I use every time I start it
👌
Do a55 cylinders runs better then the older iron a35 / a5 ones? Would those A55 have more power and torque?
A55 has much bigger transfer ports and runs cooler.
U kick ass..👍👍
its shifting too fast from first to second.whats the top speed?
He NEVER gives any numbers. Annoying.
Hey man are you possibly selling some tomos racing tt parts im from slovenia btw?
Where did you get that tomos automatic. Were they sold in USA
Yes they were sold in the USA, for many years. Since 2017 our company was the importer.
helo you
Why would you go ruining a perfectly good airbox like that?
helo
My tomos goes at least 40 kilograms
Change his speedometer to mph, he is so confused with kmph
An old trick to get the rider thinking they are faster than they really are.
You never give real numbers in your upgrade videos. I don't know if it is worth the mod. @@MopedProblems
