Hi i have just started racing at 14 and i have recently bought a 03 cr125 that was bought out of the crate in 04 it has done nothing since the guy broke his ankle, the bike still had its orginal plug and air filter and showed all the tell tale signs of a good tidy bike (no chips in forks, rips in seat etc.) but i find that it goes through plugs very quikly some people have told me to use iriduim plugs and rock oil fully synthetic others not iridium and plutioline oil. i am very confused and wondered if any of you out there have any suggestions on plugs oil or anything to do with the bike for that matter any comments would be apriceated. p.s why do mags keep saying the cr is slow?
