Tomos DMP 70cc sprinter

[Wolf1993]

I would like to have this tomos myself

[cerar_slo]

problems again
since I corrected the port durations, i had many problems but we solved all out
now: when i drive with full power, in benzin filter i cant see benzin
then motor turns off, i need to shake benzin pipe and then benzin starts runing in carb

anyone know what is that?

[cerar_slo]

update: new exhaust almost finished

[cerar_slo]

finished
im very satisfied with new exhaust, high rpm...
i will make a movie soon

[2pac]

Thats a good fucking looking exhaust

[Wolf1993]

Looks very nice

[brombertje]

Looks very good. I still love that color.
I think your top speed is much better with the new exhaust for higher rpm.
I can't wait for the video.

[Alex..]

whoa

thats one good looking exhaust

[cerar_slo]

Tomorrow i will find out how much rpm's can this motor make and then calculate top speed
im looking for 85km/h, which is fine to me

[brombertje]

85 is nice. I get top speed of 65 with 50cc engine, so you should get 85 easy with that setup.

Photoshooting when i get more pics, i will upload them and post here

8000rpm in 1. gear and 9000rpm in 2. gear which means Top Speed around 75km/h
Top speed isnt so important to me, i like good starting...
maybe in the future, i will buy PVL ignition, better/bigger modification of port's duration...

Today i took off the clutch of 1.gear which is modificated with leather, it looks same as when i put it on
I recommend leather

[brombertje]

That last pic is sweet. That exhaust looks perfect on the moped.
I also want to do my clutch with leather, i heard it is much better.
My 50cc does 65 km/h at 8100 rpm with 26 gear front, and 22 rear. What gears do you have now?

update



huge improvement from stock springs, very satisfied
motor start driving at 4400-4700rpm, at 5300 header starts working, and then 1. gear to 8000rpm
and 2. gear to 9400, which is 78km/h

good for me

[Ingmar.]

Nice to see my idee of scooter springs in tomos clutch used evrywere:D

[JesseJeremy]

It looks very nice my boy seriously

[brombertje]

Good idea to use those springs. Maybe i will do that too, looks like the KTM race clutch for Tomos.
Very nice. 1 question. I want to know if the clutch grip is very good, and does not slip like the original when i give full throttle.

1 question. I want to know if the clutch grip is very good, and does not slip like the original when i give full throttle.
