Video

At 15:30 I just tried that on my gz250 and it barely has a gap. So if that's a reliable method my cam chain must be stretched more than I thought. 127.3mm for 21 pins I can move sprocket a tooth with the slack without tensioner. It's a pain to get the clutch pieces off your videos helped me decide to tackle it.

brilliant. no pun intended, great job.

Looks fantastic

Very cool. Hope to see that bike in action on part 2! Want to see how the 300cc upgrade is holding up 🔥

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

Link for buy 300cc kit??

Looks awesome,great job men. I'm from Kenya and i'm thinking of modifying my haojin hj150,so i was wondering which colour did you use on the engine and frames? It looks awesome

What that metal band at 14:30? My guess black metal band like emperor or mayhem I'm from USA and I listen to some bands from finnland like Nightwish, Korpiklaani and Finntroll. Swedish Opeth, Candelmass Then there's various death, black metal, thrash, symphonic, folk , power metal I listen to.

C’est un 178 FMN ?

Nice light setup, man. Looks really cool.

Looking very good, are you sure that the swingarm bushes will handle all the force? I hope that they do so as it was a brilliant job making them. Keep up the good work.

Thanks for the series Kepperi. Working on some GZ250's. They have the same engine, your videos are very useful.

keep it going 🤩

Nice, good to see you working in the scooter, would you recommend that paint system?

Ingenious.👌

Very well done! cheers

Excellent work Kepperi, I don't know where you leaned your english, but those one liners and compulsory beer, makes you an honorary Australian

Hi, I also have a Suzuki GN250 project, and find your video's very inspirational, keep up the great work

Aussie guy watching your build "very Inspirational" Also very inspirational to have the right calendar girl watching your build, lol

Happy New Year .... Question on the Suzuki GN250. Regarding the air screw how var is it turned in... Can you check and give me the mm

Great video, hope you enjoyed your ham, Happy New Year.

Now you can see backwards. Excellent audio. 👌

Coming along nicely, you deserve a medal for figuring out the best way to fit the window, we have a saying, "Necessity is the Mother of invention". Good all round job. Oh by the way, can you sort out the background music volume please. 🔊🔉🔈

hi buddy how can we chatt

The build is coming along fine, keep up the good work. Oh, @10:16 that square makes a good hammer, LOL.

Great work! <3 from New Zealand

What are the dimensions of the boards?

gn250 comes in 2 power variants, one was 17HP and second one over 20. Do you know where is difference? Is there any way to unlock this 17hp version?

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?

Cual es la medida de válvulas en admisión y escape gracias

Can we put gn 250 engine block head on gn 125 engine body?

Hey :) At this moment I am having the same Moped with the same engine before me and I am searching CZcams for Restauration videos and I am stumbling over your series. How great that you already have that many videos online about this engine.

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

Thanks so much for this series Kepperi I learned a lot watching you and fixed my own gn250 along with you 🎉🎉

Hey this is awesome hope you are still doing well

it took me a few minutes to figure out that chain tensioner. it only goes one way, so you have to wind it back and then install it, like you did in the video. I am going to try an aftermarket manual chain tensioner that is just a bolt with a locking nut and see how that works.

this is exactly the video I needed to see! I stalled my GZ250 and broke one of the ears off the cam, so I decided to go ahead and do the big bore upgrade while i had it all torn apart. I was wondering how to get the timing correct, and now that I have seen how you did your I will order a new timing chain just to be sure it is within tolerance. Thanks for the help!

great to see you back doing what you do, only this time you have a manager to keep you on the right track, so things should go a lot smoother.

Happy to see you again with this new projet

Thank you, for these videos.

Where did you find the service manual? :)

Also. Where did you get the muffler from?
