Sprockets

Doesn't matter, I live in a small town where the need for high speed isn't there; but good acceleration, that is far more important with the idiots around here. Im not saying that its best for the bike, but with the amount of lights I have to stop at this set up seems more appropriate for the clutches longevity.

Kinda the opposite here, I have a 10 minute stretch of 55mph and the rest is -35-45 til the end of town.

Planning on getting a bigger cruiser for going out of town. Sadly the one I was interested in was sold before they got back to me.

No. It will have the opposite affect on your clutch since you will be shifting much more often. Frankly, it sounds like you don't have much time in the saddle. Your desire to improve acceleration by radically changing sprockets is not realistic. Here's why:

- A running properly KZ750 with stock sprockets has more than enough power to blast you from redlight to redlight. The 1980 KZ750-LTD will run the 1/4 mile in 12.6 seconds and reach 104 mph in that 1/4 mile; I'm sure the 1983 will do at least as well. That is plenty of acceleration for riding in a small town or any other town, and in actual practice you would not use that much acceleration in a town or you would soon be in the hospital or in jail.

- Changing the sprockets to what you propose will actually slow down your 1/4 mile time because your top speed at redline will be reduced to 85 mph, so your bike will be out of ooomph very early.

If your bike currently does not accelerate quickly the solution is to get it tuned and running properly rather than try to cover up the problem by changing sprockets. Obviously it's your bike and your money, but that does not alter that fact that the sprocket setup you propose is a huge mistake. I think you will recognize that fact when some kid on a 250 Ninja pulls away from you. Ed

If you go to: www.gearingcommander.com/ you can work out the gear ratio settings and RPM's.

I told you im not driving in a high speed area so I won't be shifting that much, regardless I've already talked with the mechanic about dropping some teeth, ill see about getting a tune up, just depends on the budget.

That gearing commando doesn't have my bike, I dont know what the specs are exactly but ill look it up. Ill go back to a 32 rear and get the top speed checked out.

As I've said before I could never get the bike over 8k rpm. But I never did find out the top speed either.

As you said I haven't been riding long, only 4 years, and I have much less mechanical experience than I need, or would like.

Everybody has told me that my 750 is like the ninja of the 80's. .. if there is any truth in that then I definitely need some work done.

Now a random question; anybody know where I can get a new tank or would you recommend bondo for the massive dent in it?

Also any chance of getting a tank of higher capacity?
