ok, so i have a suzuki quadsport lt230. i have just recently purchesed this machine but it needs a coupple of things. it need the motor put back in it and the plastics put back on. the reason why the motor was taken out is that 3rd gear bogs down so you have to rev it real high and skip 3rd and go streight to 4th. is putting the motor back in going to be a hard job?
