bondy Posted November 17, 2016 Report Share Posted November 17, 2016 guys are they easy to fit? Dose the lighter fly wheel cause any issues. I mean is It a direct fit? Also do you need a different fly wheel. Puller? Quote Link to comment Share on other sites More sharing options...
guys Posted November 17, 2016 Report Share Posted November 17, 2016 Mine was a direct fit. Just follow the instructions. Even the ignition timing was fairly correct when I mounted it according to the instructions, only a minor adjustment was needed because I'm a perfectionist. The flywheel came with a suitable puller included. And the lighter flywheel is an advantage in my books; it makes the engine more responsive. 1 Quote Link to comment Share on other sites More sharing options...

nigel dabster Posted November 18, 2016 Report Share Posted November 18, 2016 On the electrex can you set the timing? I like mine at 2.8btdc is this possible? Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted November 19, 2016 Report Share Posted November 19, 2016 You may move the ignition plate in slotted holes, but for precise adjustments I guess you need a strobe light. Mine is set accordingly to their spec and my bike runs well. See https://www.dropbox.com/s/zcfoxs3bbdzit58/STK-154.pdf?dl=0 2 Quote Link to comment Share on other sites More sharing options...

carl ekblom Posted November 22, 2016 Report Share Posted November 22, 2016 I have not checked it with a strobe but it should be close to 10 degrees at idle (Electrecx World spec) . I don´t know the C-C length of the conrod but if I asssume it is 1.8 times the stroke (60mm) that would be 0,6mm btdc increasing to 23 degrees (3.0mm btdc) at full advance.

netley Posted December 9, 2016 Report Share Posted December 9, 2016 Just fitted mine from Bultaco uk. £220 overnight courier. Plug and play, just needed a bracket and kill switch wired. Cured all my problems so very happy. 2 Quote Link to comment Share on other sites More sharing options...

guys Posted December 14, 2016 Report Share Posted December 14, 2016 guys how dose the flywheel fit on the crank with no woodruff key? My flywheel did have a woodruff key slot. Quote Link to comment Share on other sites More sharing options...
bondy Posted December 14, 2016 Report Share Posted December 14, 2016 Oh on reading the germane introduction It says the woodruff isn't needed? Says it has a cone I don't like the idea off that if I was to buy 1 I think id get mine from the same place has you. Quote Link to comment Share on other sites More sharing options...
spen Posted December 14, 2016 Report Share Posted December 14, 2016 I've used ignitions like this on numerous bikes, racing and trials for many years. Never had a problem setting them up without a Woodruff key. Never had one come loose or move. Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted December 14, 2016 Report Share Posted December 14, 2016 Electrex ignition for Bultaco use original Femsa flywheel so it´s a key. It just take 1- 1,5 hour to assemble and get the bike running. Quote Link to comment Share on other sites More sharing options...
