  1. Bit of an update. Did a trial yesterday with no noticeable smoke. It had shorter rides between sections so less load/heat from the engine. So all looks good. Will repack the exhaust this week then see how we go.
  2. Yeah runs fine and checked the plug today and the colour looks good with no fouling so going to repack and see how it goes. Cheers.
  3. Cheers will have a look. ?
  4. Thanks. I'm all for the conservative approach myself. Any recommendations for exhaust packing? Are the sheets on Ebay up to the job?
  5. Thanks to all for the replies. Perhaps I got a little ahead of myself because of the smoke and the fact it smelled different. I will keep an eye on the gearbox oil level and see how it goes. Cheers. Gra.
  6. Thanks for the help. Might try cleaning the front pipe out with some caustic soda and see how that goes. Fingers crossed that it helps, certainly better than a full strip down!
  7. Thanks for the reply. Looks like a full strip and refurb then. Should be able to live with it until I have a window between trials. Any advice on what else I should change when I'm in there? Also I assume when removing the mains from the case you warm the cases with a heat gun and then press them out? Thanks.
  8. Hi I am looking for a bit technical advice. I have been finding when riding between sections and putting the engine under load that it is smoking a fair bit and stinks of burning oil rather than 2t. I am assuming that my oil side crank seal has failed. Does anybody know if I can replace the seal without a full strip down? i.e pull the sealout with a self tapper screw or something? Gasgas uk say I cant but i'm sure I have seen it done on one of the models. If I can replace it without a full strip down would most people just replace the failed seal or do the flywheel side as well. Thanks in advance for any help. Gra.
  9. Thanks Birdy. Much appreciated.
  10. Hi All, just got my first trials bike 280 gg after a good few years of riding mx, h&h and most recently green laning. Looking forward to getting out and about for a bit of practice. I live near preston and am looking for practice areas. I know about cowm and will give it a look but have also heard about feniscoles and clivager. I was wonder could anybody tell me if the later two are still open and if so what days. Cheers in advance.
