    Hello everyone! i just bought my first ped the other day and it is absolutely awesome! It’s a GSR46r with an engine trix deck and rear sprocket, aftermarket air intake, dominator pipe, and what really sets it apart is that it has BMX handlebars. Yes, BMX handlebars. When i bought it the guy said that when he started it the engine would rev high and kind of stay there so he showed me. it started second pull but it did exactly as he said and revved high but wouldn’t go back down so he killed it. Could this mean I need a new spring? I’m not sure what exactly the issue is. Any help would be much appreciated. Thank you! And the motor is the stock CY460.


    Set low jet to 1 1/2 turns out and high around 1 3/4. Make sure the idle screw is touching the throttle arm only a little and that the throttle isnt screwed out too far pulling on the shaft a little causing it to rev high. Most likely the throttle cable is being pulled check that first before messing with the tuning needles.


    I don’t believe you about the bmx handle bars. Could be stuck throttle or air leak in the intake.


    Could also be like mine. I have a gp460 that I rode out yesterday for a good 2 hours, barely made it home.
    Occasionally the throttle on the carb (HDA223) would stick and revs were around 8k from 2k idle. I could tap the throttle a bit and it would bring back down but I was having surging issue. Then it would just go away and come back. Problem for me is I need a rebuild. Yours is probably the Idle screw or Low carb needle adjust (easy to do).
    Pictures tend to tell a better story.


    The carb adjustments mentioned are a great place to start. But what you’re experiencing may also be an air leak in your intake, or possibly the case or the base of your cylinder. First adjust your carb to the settings mentioned. Then check your bolts, if that doesn’t fix it replace your gaskets.
