Ok, I'm getting confused with all the ratio's and what that actually translate to in terms of performance. Does a smaller ratio mean the wheel turns faster, but with less torque. And a bigger ratio turns slower with more torque? So for your primary gear would you want a smaller ratio, and with the secondary a bigger ratio. Or is it bad to have a tiny front gear and a massive back gear. I'm kinda confused...
Cheers, that helps but...... I still don't understand the difference between the primary gear and the secondary gear as you see them both for sale. Am I just being a ditz and the primary gear is slotted into the secondary gear making 1 working gear???
right.. theres 4 gears in a box. one comes from the imput shaft where the clutch sits. this gear connects to a gear in the centre shaft (ley shaft) this is the primary gears.. the ley shaft is made up of 2 gears on one fixed shaft. the second gear on the ley shaft connects to a gear on the output shaft that the wheel sits on.. this is the secondary gearset. a ratio is worked out via the difference in teeth. so if one shaft is a 10 tooth and the other is a 40 tooth its a 4:1 ratio... this means for every 4 turns of the imput shaft there is one turn on the output shaft.. the lower a gear ratio (say 3:1) the more acceleration but less top end you will have.. the closer to 1:1 you get means less reduction in gears wich = more speed does that make sence?
what gear set would be good for a standard 50cc (with an exhaust) to make it into a wheelie machine? someone said to use the gears from the ac engine init? but why would these be diffrent?
