This was a really nice video, so inspiring! 😎✌ Can someone advice me how to choose: A Derbir GPR 50 with a little better CDI that do 70 km/h from 2009 but the Tachometer is not working as it should... but the seller want 15000 sek for that Derbi... or a regular Aprilia RS 50 from 2018 for 25000 sek? is it really the same engine in these two despite one being from 2009 and one from 2018? And what cylinder kit is the biggest I could fit on these bikes, and what exhaust system should one get for these? thanks to anyone who can help me out to make a right choice!
Did you remove exhaust restriction washer and the inlet restriction just before/after the carb? Seems like it is not fully de-restricted to me. Also the exhaust port could be really sooted up? Nice bike, I had one as my first road bike many years ago.
It is completely derestricted, however, there is something wrong the the charging system as the lights are always dim and the electric starter is dead. It is able to start if i charge the battery but it drains itself after a while. So because of this i recon the servo for the power valve system is not strong enough to function properly.
@@Twostrokesmoke You could be correct. I had a problem with the rectifier on my bike. Seemed to be a weak spot for them. Hope you get it fixed. Ride safe brother
I had 1 exactly the same done 80mph top got told max they do is 95mph with a full race exhaust :/ don't know how true that is tho as the older 1s r faster 4 sure
That is a really nice playground, and a really nice bike, but to me doesn't look like it is unrestricted. My NS125F looks way faster and the NSR 125 should be way faster
