Speedshop Posted July 11, 2011 Share Posted July 11, 2011 and so simple (so the points fraternity tell me). carry out proper checks of the wiring. Kill switch faults are favourate assuming you've gapped the points and set the timing properly. Technique is everything when starting these. Me showing how to start a big single - same engine as the XT500 - but with electronic ignition. Link to comment Share on other sites More sharing options...
Tommy10bikes Posted July 11, 2011 Share Posted July 11, 2011 It goes without saying to make sure the points are opening and closing correctly when you kick the bike over, check correct gap on the points if there old put some new ones in maybe add a new condenser check that the coil is earthed correctly make sure the cut out switch isnt faulty ( earthing out the points ) same applies for the main switch check there is some power going to the coil when you kick the bike over My guess is that if you havnt fitted new points & condenser its probably them. If all fails bring it up to my house for a week. TTB Link to comment Share on other sites More sharing options...
Jeremiah+Josh Posted July 12, 2011 Share Posted July 12, 2011 hey i love these things take plug out to start with don't worry about starting untill you have a spark or you have no leg or foot left clean block connecters from engine to loom clean the coils where they ground to frame then... while looking directly at the contact breakers (dim the lights or late in the evening if outside) turn the engine over (easy now no plug) and see if you get a blue spark arc across the the breakers . if none examine wiring (power)going into coil i think poss red/white if no power trace back to find out why (at this point try look for power while kicking over too) if you have power move forward checking each connection good luck Jez Link to comment Share on other sites More sharing options...
