Im currently fitting a full '04 fireblade red/white/blue fairing set to my nc23 as i came across it for cheap.
The nc23 bulbs are a 35w, and i cannot come across a 35w bulb for the blade headlights. will a 55w bulb fry my electrics?

Also, are the nc23 and nc29 exhausts the same. Ive currently got a standard exhaust system on but want to fit an aftermarket exhaust. All the 23 exhausts of ebay look a bit boring. I was looking for either a motogp style or an akripovic and modify them. I'm no engine expert, but would this cause the bike to run any different by fitting a suzuki bandit gp style exhaust for instance?

If you want to run the 55w bulbs you will have to do a low beam relay mod otherwise the increased voltage will burn out your switch gear.
