hello... i just spent the last 4 odd hours disassembling and reassembling my GPX250... topped up battery, changed oil and filter, cleaned and reoiled my chain... it runs a bit sluggish.. i figure its the spark plugs. i've got a PDF of the manual, but it's missing a few pages for some reason. it has a crappy photo representing where the sparks supposed to be, but i can't make it out and i cant find it. help? where the fcuk are my spark plugs?
