seth29 Posted February 13, 2011 Report Share Posted February 13, 2011 Can you help i have an old jcm 323 trial bike with the TI engine fitted. the clutch is slipping and not able to ride out of 3rd gear, as the bike is one of the first 35 bikes made it has a different clutch fitted the friction plates are more like a rear sprocket than a friction plate, there is a sureflex make on the plate but unable to find a listing for the bike or engine, have contacted them and no answer... have spoken to Joel in france but have no parts left and no part no. I think the bike has been run on car engine oil which has a slip agent in it so will mess up the best friction plates in the world. So have been messing around with spacers on the spring new springs still no luck. The only thing left is to get the friction plates relined, have you had this dun and where, have rang somewhere but they want Quote Link to comment Share on other sites More sharing options...
mattylad Posted February 17, 2011 Report Share Posted February 17, 2011 Why not try soaking in some solvent, thinners or petrol to see if this leaches out the contaminent? Leave for a few days then lightly sand with some wet and dry smooth 400 grade paper on a flat surface. Fit and run with ATF and drain soon. May not work but is worth a try.
