Hey, I'm getting a Technigas exhaust, 58 jet, but was wondering if ya'll would recommend a 22 or 24T rear sprocket. I am 240lbs. and ride a '07 Streetmate. I have VERY mild incline hills and many stoplights, although the speed limit in my city is 35 mph. I need to be able to accelerate with traffic and keep up with traffic and do at least 35 mph. Please let me know what ya'll think. TKS, Timm.
