If it's a Gen 1 could be says 74.3 at 4000 rpms


Gen 2 is 76.9 @ 4200 rpm so could be regardless of Gen

Sounds really close to an all stock Gen II. At 4000 RPM on a completely stock Gen II, you are really close to the 80 MPH mark, in 6th gear.

ok thanks, it's an 05 gen I

my 06 does 80 at about 4100 rpm. Give or takean 1/8 inch of needle play. The thing is, im now 2 up in the rear and 1 down in the front running an 18 inch rim. I still get the same R's at 80 as before, tho the rest of the range is very different. Best bet is to count the teeth, easy enough on the rear, bit more difficult to see the front

just count the teeth man, 17/40 is stock gen 1
