I have a 17.5mm DellOrto carb as well, and i know what all the right connections are.

The green one is vacuum, for use with a vacuum fuel tap. You must seal this one if you don't use a vacuum fuel tap. The red one is for the oil feed line. If you use mix fuel, close this as well. The big connector on the other side is the fuel intake. Don't leave any connections open, as they suck in air, messing up the mixture. Always put in the choke, and connect it to 12V DC (battery) if it's electric. Otherwise it messes up your fuel mixture. I can suggest you should buy a hand choke. They are cheap, and don't use 12V DC.
If you connected the carburator good, with an air filter, warm up the engine and drive full throttle for a little while and stop. Turn off the engine direct and check the spark plug for the right color. Black = too big main jet. White = too small main jet. Adjust main jet until the spark plug is nicely brown colored. Screw the idle screw a bit in so it runs a bit faster. Screw the air mixture in. Then screw the air mixture screw out 1.5 turns. If you give full throttle, and the engine does not go full rpm directly, turn out the air mixture screw until it reacts good. Then set the idle so it runs nice and slow with a warm engine. If you drive full throttle and the spark plug turns black or white again, change main jet until the plug turns brown again. If you have problems running 1/4 to 3/4 throttle, you can change the position of the needle with the small clip which holds the needle in the throttle slide until you have good reaction overall. Sometimes you have to change little things until it is totally perfect.


I have a 2004 Standard, and adapted it for a A55 Streetmate cilinder. I run with main jet 58 with a home made filter, and reach top speed of 65km/h with A55 Streetmate cilinder and Tecnigas Next R exhaust. The filter is made from a rubber that fits good, with a double layer of strech underwear. I use this because i don't have an original A55 air filter and a power filter does not give any improvements, and i have to use a bigger main jet.

today was the test drive
Im satisfied with homemade electricity because it quickly gets rpm.
I was driving cca 30min, when Accu emptied, so i need to refill it

speed with Gilera runner counter was around 70km/h with 26-26 gears

Nice :D
You can use a voltage regulator for e-start (4 pins) to charge the battery when you are driving.

Bartelli Ricambi and DMP also make these, but a lot cheaper or buy a second hand one.
If you want less weight, don't use a battery, but only the voltage regulator.

Edit: Why do you need a battery?

i need battery for ignition
ignition is homemade and it is like ignition for car

when battery is empty, ligtning at sparkplug stops

I thought so.
You can connect the voltage regulator with 4 pins directly to the ignition if you use the ignition in the from Tomos with the yellow/black wire. This regulator has a 12 volt DC pin that you can connect to the power of your ignition, where you have the battery connected. When you kick, you probably should have enough power to get it starting, or use this regulator with a very small 12V battery to get it going and charge it driving if it does not start without battery.

Wow, a real home made ignition. Nice! How did you make the timing work? :o

i set ignition 1mm before piston comes to the top of cly
then you connect 4 cables in ignition and this is it

I really like the home made ignition and the colors. Very nice project. 8)
I want to make my own programmable CDI ignition with rpm sensor so i was very interested in your ignition.
