Hi all, got a golden special with a steel 175 kit, 42 mm clubman, carb is one of those reworked jettex from cam lam, 120 main jet BR9 plug, runs great but feel it could do with upgearing a wee bit.
its running 46 crown & 16 front sprocket , if i fitted a 17 front sprocket would it pull it ok ? just asking before i get a new 81 link chain

Does it pull strongly in fourth but seem to be revving hard flat out ?
If so it might stand an extra tooth, you don't say what gearbox is in there?

If you have an idea what it's revving out at try one of the gearbox calculators

Might give you an idea of what to expect for the effort / expense.
