alec2507 Posted August 3, 2009 Share Posted August 3, 2009 hi, i'm no mechanic so if this is totally ridiculous please tell me, but if the oil seal behind the front cog (think its the crankshaft oil seal ) is leaking would this make a difference to performance, i only ask as i as looking at bikes on ebay and one said its not pulling like it used to as oil seal is leaking (it was an rxs100) cheers alec Link to comment Share on other sites More sharing options...
