Re: best gears for 97 elite
hello welder steve. , if 55mph is your goal 8.4:1 gears should be a nice fit.
new best 1/8th mile time 9.647 seconds @67.155 mph 310lbs total weight

Re: best gears for 97 elite
Wouldnt mind knocking at 70. How much does this bigger tire change the ratio

Re: best gears for 97 elite
Thanks a load was wondering how the tire would affect speed, is the 90/90 taller or shorter than the 3.5?

Greetings:
90/90 tire treads sit 3.18" above the rim. The 3.50 is nominally 3 and a half.

Re: best gears for 97 elite
Greetings:
Yeah I'm heavier. Like DOUBLE... .
Forum members should know that the gears don't make all that much difference in acceleration EXCEPT for "Zero to Whenever the Clutch Fully Engages" - which depending on gears can be 4-12 MPH. This is true as long as the variator is tuned to keep the engine zinging wherever it makes its best power. The only time I cuss at the tall gearing is in slow traffic, like in a long line for a Stop sign. Behind a bevy of Buicks with blue-haired drivers.
Hills, or running at 15 MPH but at a steady speed are no problem at all. Remember the Variator controls the engine's RPM. IF it's correctly tuned, gears only make a difference in Output Shaft (Wheel axle) speed before the clutch engages after the variator maxes out, presuming it can. A lower-powered engine should see the same 40-MPH top speed whether you run 12:1s or 6.9s. The difference will be how much of the variator's travel it can use. A higher-powered engine will run out of usable RPM before reaching its potential top speed if the gears are too short. Does this make any sense?

Re: best gears for 97 elite
Yes that makes perfect sence, i understand the workings of the variator, but was mainly wondering about the acceleration aspect as i know weight makes alot of difference in acceleration, so i figure if someone that weighs 100 lbs more than i do is comfortable with the acceleration, with a given gear ratio thanks
Re: best gears for 97 elite
in theory yes that's how it should work. But only if thete is no load for the motor and trans to push. A good example of over gearing is when you went from 8to1 to 7.58to1. You went from 68mph to 69mph. 1mph gain on a gear change that in theory suppose to be 5mph faster or topspeed of 80mph@10k rpm. You were no where near that. So your theory which sounds good and makes using smaller gear ratios sound good doesn't work the same. Again over gearing has always been a problem with guys from hawaii that say you should be running these small gear ratios that are ment for full race stroker setups that race teams don't even use because they are to much.unless your making 17+hp on a 72cc motor, you will never reach the full speed the gears suppose to go unless your going down a steep hill or getting pulled behind a car.so for 72cc-86cc no more than 8to1Wheelman-111 wrote:Greetings:

Re: best gears for 97 elite
Greetings:
I believe the reason I gained onlo 1 MPH on the first try was that the engine didnt make enough Power to go faster. It spun about the same RPM, and 69 was all it had. Switched to 26 OKO, more tuning, and got to 71.2.
That said, I agree that theres no point putting up with so much pain off the line and leaving half the variator travel on the table with too-tall gears. Dont forget belt and tiny tire slip as other reasons for not achieving Theoretical max speed.
