hi, can anyone tell me what gearing they are using with a 17" rear wheel in an nc30 please ?
ive changed to a 17" rear wheel and now the bike is reving / working far to hard
would be gratefull for any help
cheers .

I reckon that most people don't change anything as it is not that much of a difference,

What gearing have you got already? What is the bike used for?

I have a 17" rear -1 on front +1 on rear, all I can say is WOW I love it!
Before changing the gearing, the 17" wheel on it's own didn't make a major difference.
Carbs have been fettled too
