malcra Posted June 19, 2008 Report Share Posted June 19, 2008 I've managed to acquire a reed block from Steve Goode and it fits my Jumbo; article here . There are the recommended carb settings the in original SWM document for with and without the block but interested in knowing other peoples settings (that work) are Quote Link to comment Share on other sites More sharing options...
mattylad Posted June 20, 2008 Report Share Posted June 20, 2008 I have a Jumbo with reed. I use standard jets and needle in third slot (richer) works for me but the timing is critical! Quote Link to comment Share on other sites More sharing options...
malcra Posted June 21, 2008 Author Report Share Posted June 21, 2008 good point on the timing; to date I've done it a little by random, so any suggestions on timing points welcome Quote Link to comment Share on other sites More sharing options...
mattylad Posted June 24, 2008 Report Share Posted June 24, 2008 I time my bikes to standard then whilst practicing advance and then retard a little. Testing this way means all things are equal and the effect of timing are evident. Obviously dont ride in water!!!!!! Quote Link to comment Share on other sites More sharing options...
malcra Posted July 1, 2008 Author Report Share Posted July 1, 2008 so, I've following Martin's advice from an old email I had and rotated the stator plate clockwise by about 2mm; retarded the timing. Pulls like a horse now, and with the reed block, the pickup from pilot->main a lot better. Need to sort the exhaust etc but all going well Quote Link to comment Share on other sites More sharing options...
