asimo Posted October 8, 2014 Report Share Posted October 8, 2014 hi guys I did my first trial on Sunday in the rain, this was 30 years since I last rode a Sherpa t 350. I really enjoyed getting back into trials and want to keep on going with it. I have a Sherco 2004 200 cc 2 stroke. it has a tubeless tyre on the rear. I had to remove the tyre to fix a spoke and now the nipples leak all the air out... can anyone please help me solve this problem???? regards Asimo Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted October 8, 2014 Report Share Posted October 8, 2014 When you fixed the spoke you had to remove the giant rubber band from inside the rim, right? That rim strip must be properly installed into the groove in the rim. They can be very tricky. Jim Snell made a really good video that you can see on youtube. http://www.youtube.com/watch?v=1sAD6l0ORVg&list=PLfrG78Ca76TbmQbYODIpXU4Inj8Lpi8JT Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 8, 2014 Report Share Posted October 8, 2014 http://www.geocel.co.uk/catalogue/single-brand/trade-mate-range/trade-mate-lead-and-gutter-seal You can seal the band in with the above sealant. DO NOT use an acetoxy type sealant it will cause severe corrosion Alternatively replace the band with a screw in valve and coat the wheel well and spoke nipples with a 2 mm layer of sealant, then a couple of layers of PVC tape. The PVC tape stops damage to the sealant when fitting tyre. Quote Link to comment Share on other sites More sharing options...
grib Posted October 8, 2014 Report Share Posted October 8, 2014 I would suggest not using sealant unless there is damage to the rim which is causing the leak. After watching Jim Snell's video I have fitted several rim bands and they all sealed first time. I use tyre fitting gel instead of soapy water though.

dadof2 Posted October 8, 2014 Report Share Posted October 8, 2014 http://www.geocel.co.uk/catalogue/single-brand/trade-mate-range/trade-mate-lead-and-gutter-seal Try sealing your rim band with this or, remove the rim band, fit a bolt in valve then smear a 2 mm layer of gutter seal in the wheel well and over the spoke nipples. When dry over with a couple of layers of PVC tape to protect the sealant when fitting the tyre Sikflex car windscreen sealant is also OK but DO NOT use acetoxy sealants as the will cause serious corrosion Quote Link to comment Share on other sites More sharing options...
tony27 Posted October 9, 2014 Report Share Posted October 9, 2014 Being an 04 model chances are it still has the tape with the separate valve stem, spend the £20 & fit the newer type with moulded in stem. Those separate parts are a absolute pain to fit without something moving Quote Link to comment Share on other sites More sharing options...

richt Posted October 9, 2014 Report Share Posted October 9, 2014 Hi Asimo, I posted this a few weeks back and my tyre has stayed up ever since; My rim was leaking so I removed the rim band that the previous owner had unsuccessfully used Evo-Stick and so cleaned it all off with petrol. Bought some 'Plumbers Mait' this none setting, water / chemical proof and very very sticky sealing putty, Spread an ample layer 2 to 3mm thick covering all round the centre of the rim and then refit the rim band. Pressing the band down into the rim and removing the excess as its squeezed out, this takes a while. This could seal rims that may in very poor condition. Worth a try. Result is totally air tight. The nature of this product could be a long lasting cure and because it doesn't set you can still tighten spokes or if you ever need to replace any spokes it can be taken apart and resealed easily. Cost £3.60 for 750g, got loads left I estimate this size of tub would easily fix 5 wheels. I guess I just need some friends to use it up.
