Ok il try explain in as much detail as i can. Basically my aerox has shit acceleration up hill unless i have a run up and the powerband kicks in. If i turn from a corner and go straight up a hill even if its not very steep it crawls up slower then walking speed and i look like a d1ck. I dont know what the bikes had done to it because i bought it not long back. But it had the oil tank removed so i have to pre-mix the bike at 25:1 ratio. It smokes alot but i got told to use that ratio by the previous owner. It also drinks petrol very fast so im guessing it has a bigger carb fitted. Im new to scooters so dont know everything but if i need to explain in more detail il try to. I also dont know the rollers size etc sorry. Thanks Tom
