Hi all im new to this forum stuff but not all to new to bikes.. Only on L plates but im gettin out there. About 2 months ago i bought a little k-reg rxs to get around on but little did i know when i bought the bike its missin part of the gear select shaft aparently n because of this theres a monumetus completly unfixable oil leak where part of the inner caseing has been torn off.. The bike runs n rides okay hasnt failed me yet i had the 125 version last year and i know these bikes are bullet proof, but it only holds enuff oil to wet the cogs and as i start a new job soon i need to know its gunna get me there.. Dont supose anyones got a spare workin motor for one of these lying around? Or know where i can get one. Cheers
