hey there,
Check out my pic in my profile, ive got a zxr C.
the C model has different head lights and slightly different fairing and tank cap to the A model, plus A model has more hp.
Just like the Honda cbr R's have more hp than the RR's.
I get 250kms out of my tank and not much more and ive even had the carbs synchd!
I previously owned a cbr R (MC19) and got way better mileage out of her and found she was more reliable (cam gears).
But the zxr C looks better!
The zxr C has 42hp.
I have a workshop manual tht i could email u or watever, let me know.
Ive never had trouble getting parts for her, and i mean all parts are about standard pricing, but you can normally get them cheaper on trade me or bodgy up the job urself, its all a learning curve and its a lot of fun.
good luck!
