My son order a 2 stoke engine kit from GasBike. After assembly the clutch will not engage. Called GasBike and informed them of issue. Gasbike advised to adjust the clutch. We told them the clutch is as tight as it will go and it simply slips around the clutch pads and does not engage at all. They said there is nothing they will do about it. So, we are just stuck with something he paid for but will not function. We will buy and install new clutch pads, but we believe GasBike should be willing to supply these without change. They offered no help at all. Bottom line we are on our own to deal with this.
