[@MrParkdrive]

That was fun to watch .😊 Don't know why but I had a bit of suspense

[@KepperisGarage]

Thanks @MrParkdrive

Con questo lavoro di quanto sono aumentate le prestazioni? E hai messo anche un carburatore più grande o hai lasciato quello originale?

[@KepperisGarage]

I did not ride this motorcycle before the conversion, so I cannot really tell the difference. The carburetor has a larger main jet, but is otherwise standard.

I have a 1994 model gn250, I want to upgrade it to 18 pin 300cc, can you help me and I want to install an ax crank?

[@KepperisGarage]

Sorry, I have no experience on those later models 🙁

[@upsidedown1986]

Will the big piston and rings fit Suzuki GZ250 also?

[@KepperisGarage]

Hey Mick! Sorry, i don’t know

[@thaomypham5216]

how is the top speed testing Mr Kepperi ? Also how is the fuel consumption after the upgrade ?

[@KepperisGarage]

Hello! Current situation is that I have to change the regulator/rectifier before i can ride the bike. I also found out that the tank is leaking 😭 Im also upgrading the garage before winter breaks in, so i currently cannot work on the bike.

[@KepperisGarage]

It seems to be unavailable at this moment, but it was from aliexpresss 🤷🏼‍♂️

[@marinosk.1826]

[@KepperisGarage]

Hi Marinos, sure thing. Remember to check the sleeve size/diameter before ordering the kit because there is those 2 different kits! Heres the link into AliExpress: a.aliexpress.com/_mOHtXFd

Ainakin Aliexpressin mukaan pitäs käydä molempiin www.aliexpress.com/item/32439301151.html Muistaa vaan mitata sen sylinteriputken koon että mahtuu lohkoihin 👍

[@KepperisGarage]

@@karirissanen5876 mullahan siis on yksi ylimääränen 300cc pytty itellä, kun tilasin ensin vääränkokoisen. Jos mittaat sen lohkojen sisään menevän "mäntäputken" ulkohalkaisijan ni saat multa halvalla mikäli sopii.

[@karirissanen5876]

@@KepperisGarage ok..voi mennä kyl vähän aikaa vielä kone dr350 rungossa..löytyy myös mäntä?..tiiviste sarja, kytkinlevyt uudet valmiina..Look and see..hyvät videot!

[@KepperisGarage]

Mäntä ja sylinteri löytyy. Voin viel tarkistaa tarvittaessa. Ei kiirettä, ilmottele 👌

[@gaetanocozzuto688]

Avresti dovuto misurare prima il foro blocco motore

[@KepperisGarage]

Ciao Gaetano! Hai ragione, avrei dovuto farlo. forse ho imparato e lo farò la prossima volta :) (sorry my Italian, its from translator)
