That's allot of work for minimal gains.Wy wife wants to ride on back and she is heavy. I'm going to need more power. Anyone know how large the NC 700 motor can be bored out to.
Agreed. I was throwing that out more to show that the small power increase of the 750 over the 700 from a 75cc gain was not worth the trouble, even if it could be bored.[Probably can be bored at least from 670cc to 745cc, since Honda did it.]
My guess is that a larger size liner was used for the 750 because they'd still want adequate wall thickness for strength. This also allows thickness for reboring in the future where a 670 bored to 745 will probably be at the limit.
Honestly, I don't think anyone rebores a modern, street bike engine any more....much more practical to buy a bike with a fresh engine or one with more power!
Adding Mass (weight) lowers acceleration: A = F/M. The force that an engine produces is Torque. The transmission and final chain drive multiplies torque by decreasing decreasing RPM's of the engine. (works the same way as levers and pullies ) Adding teeth to the rear sprocket will change the overall drive ratio and help maintain acceleration.Wy wife wants to ride on back and she is heavy.

I think this is some great advice. My wife only weighs 135. She barely made it two hours and I have an aftermarket pillion. If your talking a long trip, with panniers and topbox, things are gonna be tight and little room for her to move around and get comfortable. Especially her legs.Like all opinions...here is another free one Take the wife out for a ride and see how it goes. If you think it doesn't have enough power it is probably best to get a different bike. If you think it has enough power then you get into comfort. My spouse puts up with it but her limit maxes out at a couple of hours.
Power is (essentially) the rate at which work is accomplished, or the time it takes to accomplish the work. The _power_ output of an engine is the only thing that matters to performance (acceleration as well as top speed). The transmission's job is to make the exchange between rpm and torque, but the amount of power the engine is making at that particular time is the cap or maximum rate at which work can be accomplished.The force that an engine produces is Torque. The transmission and final chain drive multiplies torque by decreasing decreasing RPM's of the engine. (works the same way as levers and pullies ) Adding teeth to the rear sprocket will change the overall drive ratio and help maintain acceleration.
Power, as in HP or Watts are scalar quantities and are the ability to do work, not Forces. The work done by vehicle engines is moving the vehicle through a fluid (air). Therefore, to a first order approximation, Torque determines acceleration and HP top speed. Getting anything more than an increase i decibel output from the NC engine is harder and more expensive than it's worth.
