Hey guys Hope you Can help https://www.youtube.com/watch?v=NGjI...e_gdata_player
has it been broken in? has it been tuned? acceleration could be from lsn needing leaned out. tighten the screw on the spur gear in a little. looks way out compared to mine. might have too much slip. maybe a better description of what its doing?
It starts fine the needles i hold on factory setting but when it runs it revs hard sometimes it run a Little when i give it throttle but its really poor. But I Can see that the whell nut sometimes unscrew when the whell bar are running :-)
Romove the rear wheels and check to see if the wheels or the wheel hexs are stripped.
No slipper/tall gearing/power = broken parts.
I took the wheels of and it looks just fine, but ill try to start it to check on it
