2stroke4stroke Posted December 27, 2015 Report Share Posted December 27, 2015 As you are obviously a newcomer to the trials scene I should reassure you that, while you won't be able to get a replacement stator, it should be possible to get the faulty components replaced, and with better than original. Bradford Ignitions replaced the trigger coils on an obsolete Beta stator for me. Quote Link to comment Share on other sites More sharing options...

worldtrialchamp Posted December 27, 2015 Report Share Posted December 27, 2015 would you attempt to repair electrical faults in your home? no you'd seek an electrician. take your bike to a mechanic Quote Link to comment Share on other sites More sharing options...
lineaway Posted December 27, 2015 Report Share Posted December 27, 2015 You might remove the silencer and see how it runs before jumping to conclusions. A plugged up exhaust is very similar. 1 Quote Link to comment Share on other sites More sharing options...
jamiemarshall283 Posted December 27, 2015 Author Report Share Posted December 27, 2015 My dads a heavy goods mechanic and auto electrician, he has began looking at it, he says that the woodruff key on the crankshaft/flywheel has sheard putting all the timing out. He's had the stator off and tested and cleaned but cannot find any timing marks to time it correctly. He marked it in the original position but says someone has had it in bits before and he's not sure if it has been timed up in the correct position. Does any body know of any timing marks or measurements ? Thanks Quote Link to comment Share on other sites More sharing options...
lineaway Posted December 27, 2015 Report Share Posted December 27, 2015 The older Beta`s were quite known for shearing the key. Should just be a new key and leaving the timing alone. Quote Link to comment Share on other sites More sharing options...
jamiemarshall283 Posted December 27, 2015 Author Report Share Posted December 27, 2015 Thanks lineaway he's on with making a new woodruff key out of an old spanner ! He says it needs to be hardened and that's why he's using an old spanner ! I'd rather he bought one but it's hard to stop him when he gets going. Thing is he bought me the bike so I could have a go at trials, says he is not spending a fortune on one till I've proved I can handle one and am going to stick at it , it hasn't ran on full throttle since I've had it !

collyolly Posted December 28, 2015 Report Share Posted December 28, 2015 Trials is not about full throttle, perhaps that is your first lesson ! Quote Link to comment Share on other sites More sharing options...
tshock250 Posted December 28, 2015 Report Share Posted December 28, 2015 Trials is not about full throttle, perhaps that is your first lesson ! Maybe, but if his bike won't rev more than half way, he's going to get pi$$ed off very quickly, if he doesn't get hurt attempting any climb first. 1 Quote Link to comment Share on other sites More sharing options...
