The rev. counter is now fitted (A small OS from Techni Tacot with a 12 to 6 volt converter) but I scared back of going over an indicated 3000 rpm that sounded quite 'busier'... However getting to grips with the 'box and having less loss of momentum when changing to 3rd learned that some slow acceleration actually did occur...
As a matter of course I will take my standard low compression/3-speed 'box RM to 30mph in second, which equates to approx 3500rpm; if necessary I have no qualms about extending that to 35mph+, which is a little over 4000rpm. 3000rpm in second equates to 27mph, which would mean engaging top at perhaps 23/24mph or 1600rpm - I wouldn't expect much acceleration at that sort of speed!
