I run the bike on regular fuel 98 octane in this clip but I think it will also work with 95 octane because I have a moderate boost, just about 0.4 bar at 10000 rpm. My plans for this build is not to get maximum effect from the engine because I want reliability instead of max effect.

Hi, You can read a short version about the build in english here www.vintagehondatwins.com/forums/showthread.php?1879-A-totally-stupid-project-a-supercharger-on-a-CB250N There's alot more to read about this build and the thoughs before the build started on two Swedish forums, sporthoj.com and maskinisten.net, without the knowledge from the people on this two forums and a nice guy from australia I think I never had been able to do this build. This project has been going on for over two years now and it was really nice to take a short test run before the winter to know that there's hope that this build will work, just a couple weeks after this video was recorded we got the first snow here. I will continue the build this winter with new exhausts, a new rear fender and alot of other things on the bike.

Thanks. This is very cool, I noticed that you've been working on it for a long time. I'm waiting for more videos with this cool motorcycle. I live in Russia and have been looking for something similar to your project (Supercharger) . Good luck to you

I'm not remember exactly but around 50 mm diameter on the crankshaft and 95 mm diameter, this geraring will give around 0.7 bar at 10000 rpm.

Yes, it got more power. Now I use the stock CV carb on the bike compleded with a Mikuni ACP-1 accelerator pump. I haven't still flat it out, but I got about 0,65 bar in boost at 7000 rpm with almost wide open throttle. When I run the superchager in a draw thru application the throttle position will change the boost pressure beacuse the throttle will choke the superchager at low lift. I think I now got somewhere between 45-50 hp from this 250 engine at full throttle.
