I went through four K2F mags. Had nothing but trouble with all of them. Had a couple rebuilt by what I thought were reputable repairmen, but who can you trust? Maybe just bad luck. One thing I hated about them was the difficulty of changing out the condenser. Its a poor design. Why spin the windings when you can spin the magnet instead and get rid of the brushes?
I think it might have been a packaging issue as K2Fs are long but slim, where as the rotating magnet SR1 &SR2s are short but tall, much the same as Morris & Hunt mags.
I checked with Stephen Kelly at Tri-Spark. He stated that his ignition will fire on the first compression stroke, has an advance curve that will deliver 25 crankshaft degrees, and will advance a few degrees at idle if necessary to help keep the motor running while idling. He also said he believes the Boyer is more of what you are referring to in regards to when it will initially fire.
I did some more research and yes the trispark and pazon both spark within the first revolution. Magnetos with points also spark within the 1st revolution. But the magneto CDI needs to build up a charge and turn before it will spark. That charge needs to build in a magneto but with a battery powered EI it can spark immediately.
Actually a friend and I both had very serious issues with Jo Hunt. Twenty years ago now. Two new magnetos. Bought directly from Jo Hunt in USA. Issues included cam assemetry, rotor disintegrating and snapping shafts, leaking seals, needle punching of shaft to get bearing interference. Abuse on the telephone telling us we didn't know what we were doing.
Is there a chance this was what Norluck was battling?
Not really.
Sorry to hear that Johnm, I have never had any problem with JH, but the JH on my old 81 Triumph Thunderbrid I brought off a mate second hand back in 82 but it was rebuilt, the JH for my Norton I brought through Lowbrows was $20 cheaper than JH but I have brought tune up kits through JH for the old JH maggie as well a new coil, just recently I brought 2 tune up kits as well 2 spare front covers for my spare parts cabinet and have had no problems with ordering them and postage to Aus from JH.
Hi Ashley
No Norluck just didn't listen or accept advice and was doing things wrong with his set up, I kept telling him through PVT messages what he was doing wrong and he hassled me for months before he even brought his 2 JH maggies asking for advice, I think he just upset Jim as well JH themselves as really he was just setting it up all wrong, after sometime I just gave up on trying to help him and he got off side with a lot of people in NZ who were trying to help him, just couldn't get through to him and his way was always right even when it wasn't.
