Gearing for my Rb20

Hi people can anyone help on my gear set up, I've just bought the rb20 with a 34 delly, franspeed tourer, and gp200 Indian gears.. Was looking at 46 sprocket which will give 5.11 ratio or maybe the 47! Has anyone running similar set up at all? Or would it be best changing for a li150 gearbox... Will be doing both solo and 2up riding
Cheers in advance

by Tune it, to oblivion
Pacemaker gearbox with 17/46 sprockets is pretty hard to beat

Definitely don't drop below 5.00, or you'll lose the real joy of owning a rev happy kit.
GP200 with 18 x 47 standard gearing will suit it fine, AF close ratio box slightly better if you can get one.

BTW you'll probably get more replies if you ask the mods to move the thread to the Lambretta section.
