Suggestions for improving performance
Hello,
I am trying to get better performance from my recently purchaced Honda nx 400 Falcon that I purchased in Santiago, Chile.
It seems to be lacking in power. I have a difficult time maintaining 100 kph except for on the flattest of terrain and it is a real pig when climbing (me 90 kilos, load 30-35 kilos). It feels more like a the 1978 xl 250I owned when I was a kid. The 1979 400 cc Kawasaki LTD I had would easily cruise at 75mph with two people
I am considering lowering the gearing by getting a smaller (1 tooth) front sprocket and am wondering what differnce I can expect this to make as far as overall performance. I am sorry to say that I do not know the size of the front-rear sprockets now so I hoping to get an idea ¨in general.¨ The bike is at the mechanics now, so I can´t run out and count the sproket size. I am having the valves and carb adjusted, but am assuming this will not make too much of a difference. Right now she is at about 5000 rpm at 60 kph. Fifth is only useable on the flats and I am down shifting on the slightest of inclines. She is also a little tall in the first gear for negotiating technical terrain with a load. Can anyone venture an educated guess at how much differnce a smaler front sproket might make? Should I consider two teeth lower?
What else I can do to get a reasonable performance level for a modern 400cc. Possibly K/N filter?
Sorry to be so vage but any info would be appreciated.
BTW, I have found out it´s sprokecks are 15t & 40t.
