scorpa01 Posted February 23, 2012 Author Report Share Posted February 23, 2012 do you really need to split the casing to do this job ?????? Quote Link to comment Share on other sites More sharing options...
tltel Posted February 23, 2012 Report Share Posted February 23, 2012 Hi you shouldnt need to split the cases to change the seals, if that is what you need to do. In my experience it is usualy the fly wheel side seal that suffers the most because it is running dry on one side(this should make it run weak if it fails). Easy to change once fly wheel is removed. You can carefully insert two small self tapping screws into seal and then pull seal out whithout damaging the case. oil up and pop new seal in.The other side should be the same but you will have to remove the clutch and water pump gear to get to it. before you do all that I would make sure the exhaust is clear as it could be full of gunk that is burning, clean air filter and make sure you are using the recomended 2t mix for that bike. Is it using gearbox oil? You didnt say if this is a new problem or have you just bought the bike with this problem. TLTEL Quote Link to comment Share on other sites More sharing options...
scorpa01 Posted February 24, 2012 Author Report Share Posted February 24, 2012 hi there thanks very much for the detailed reply it was smokey when i bought it but not as bad as it is now to be honest ,i never thought about the exhaust being full of crap , but how would you clean it as it is a sealed unit ???, it does seem to use oil thats wot makes me think it is the oil seal it uses about 75/100ml after about 4 rides for about 4/5 hrs each ride . i'm gonna try and get a video of it running and post it up . Its not that bad on tick over but when reved plumes of smoke. ;( Quote Link to comment Share on other sites More sharing options...
