hey guys, I have a 1982 kz440 ltd. Im kinda thinking of getting a smaller rear belt pulley for it because it doesn't seem to go very fast. usually when im cruising around doing 60 kph, im in 6th gear @ around 3000 rpm. does that seem right? I think in order to be doing 100 kph, I would be at around 6-7 thousand rpm......I haven't taken it out onto the highway for that exact reason, because I think that I would be reving the piss out of my engine. I know the engine redlines at 9 grand, but does this seem right? Are you other kz440 owners getting the same numbers? My buddies midnight star will do 100 kph in third gear no problem......thats a huge difference, and i know its a totaly different bike. But i would like to hear your opinions. Thanks in advance.

Hmm, I dont know about kph but with our two banger KZ440s i dont think its too abnormal to be revving high in top gear. In top gear at about 60mph im at about 5500 - 6000 RPM, seems to match my speed, fastest I went was 80mph and I was at about 7000 RPM or just below.

hmm....so this thing is ment to do those rpm's, with no problem? and they will do higway speed no problem?

My 550 runs about 7k-7500 at somwhere between 75 and 80 mph..Although, I don't run it at that for very long, 7 miles or so.

yea, thats kind of another concern of mine.....how long could you really run and engine at that rpm??? sounds like a pretty stressfull run for an engine.

*bump*

Im planning a couple of long trips (9-10 hour+) in the next month or so, just wondering if its not a good idea to take the interstate if im going to be revving at 6-7000 for the majority of the journey...
