why carry on with a 45 year old carb ?
because the scooter is 45 years old and i like my gp 200 original.
i know a lot of people swopping reedvalves for a sh20 carb on their sx
nowadays. seems there are also people in the lcgb-forum wanting 20/22 mm dellos...
generally i agree with using a better modern carb ( the mikuni 24 is a top choice), but on restos i (like many) am fed off with worn out and choke-stripped and screwdriver-butchered sh20 / sh22 dellos.
(at least the f@@king clamps could be remade...

)
