Well the 17/49 are taller than the 16/50 by 1 tooth on each so little more mph if you scoot can pull them. I think I might be just a tad shy of taking full advantage of them. I want to try the 7g and see how that is. I really don't want to beef up my engine anymore than it really is-- I think the main thing I have going for me is my body weight. I only have a 72cc(80 some call it...) with a stock airbox without the snorkel, and a 78 main jet. I do have another carb that I thought about jetting in the  -  -90ish range and putting a uni or K&N filter on, and just swapping that setup out on days that I feel like it. It'd only take a couple of minutes. I like to ride my scooter to work-- which could be 80 miles a week for just work, at basically full throttle. My scoot takes a beating as is. Another reason why my engines don't last 15-20 thousand miles. Who knows what RPM's I'm at, or was at, during all 41,000 on the odometer of thing (different engines/cranks of course). On a side note, I'm ordering a Tach tonight. |

The stock gears were 51/15. 15/51 so 2 up and 2 down 17/49 will be perfect, you should see 6-8 mph on the top end and your 72cc should have no problem. Alleyoop |

You do not seem to get what gets you more speed, 52/14 is for low end pull NO top end whatsoever. You have to go up on teeth on the counter shaft and less teeth on the final drive gear. Just think of the CVT belt climbs up high on the variator CREATES a BIGGER WHEEL and the belt drops down in the CLUTCH PULLEY creates a SMALLER WHEEL and a BIGGER WHEEL turns a smaller wheel many more times. |

Lol, Alley--- I'm aware of that, but they "claim" higher top speed in the description. That's why I posted that. I remember those gears waaay back in scootdawg days.
Maybe higher top speed over a span of 50 feet..

Don't ever believe what some of those dealers say they just sell the stuff they do not know what they even do or how to install anything. They are just sitting behind a telephone waiting FOR YOUR CALL  |

I'm not really sure what else to change-- I prefer a bit more power/torque(whatever) at lower speeds (from 0-35 on my speed-o) than what the 49/17 gives me. I'm not sure if lighter than 7.7g rollers would help, but I do have 7g coming in the mail.

Only way to get more bump from 0-30 is higher revs, just like at the dragstrip you put in the clutch and bring the revs up to around 2500 rpms and pop the clutch. Same thing with the scoots, you want the clutch to grab the bell at a higher rpm so the motor is making more power off the bat. You can put in stronger clutch pad springs that will require higher rpms before they get thrown out and grab the bell.

If u want better takeoff without doing much just put in a stronger main clutch spring and stronger clutch springs u will be satisfied . There is a big difference between a stock main clutch spring and a 2000 rpm clutch spring . Also up hills I gain about anywhere from 7 to 10 mph up hills with a 2000 rpm main spring . There is a hill near my house if I get a run at it with the 2000 rpm spring in I hit 55 up the hill and I only hit around 45 with the stock spring.

Thanks guys.
One thing is for sure-- it doesn't even sound like I'm going anywhere on this scoot anymore, lol. This thing is almost too quiet now.
