new gears

[afroman]

I changed my gears on my 96 EXT 580 From 20/39 to 19/40. I have gained a crazy improvment in the bottom end and I understand I will lose about 4 or 5 mph off the top end but I never see that anyways. My problem is I think it now reves too high when I do wind her out (apx 9000 rpm) what do I do to change this? can I just adust something on one of the clutchs or do I need a new spring? and once this is done will i loose some of my crazy power of the start?

those are the same gears i put in my 97 ext 580 and i max out at around 8200 rpm.are you sure you have the right belt on it?

[afroman]

I have the right belt but its a couple of years old and starting to break down. whould replacing the belt change the rpms? I understand its probably stretch over the years.

What does the deflection look like? Is the belt up on the clutch or is it riding down in the clutch?

[afroman]

the defl'n is about 2" when I push inbetween the 2 clutches. the belt rides about 1/8" to 1/4" above the secondary.

[fun1]

you should only have about 1" of defelection. You need to add or remove the washers in the secondary. This will greatly effect your rpm's

[afroman]

how high should the top of the belt be sitting above the secondary clutch shieves or does it matter?

[fun1]

defelection should be 1" to 1 1/4" and your belt should be flush with the secondary.
