lol, getting back to that 16 bit processor with espresso machine and five repeateable alarms, arent we?
one, i personally think most of this nonsense on advance curves is just that. there, i said it.
yamaha, kawasaki, honda...bultaco, gas gas, HD, suzuki, nsu, sachs...dolmar, stihl,mcculloch, shindaiwa,robin.... not one user settable cdi amongst them as a standard item. all on engines with a lot wider power band than a cruddy little HT.
i will admit that there are major faults with the HT, that makes cdi changes necessary. this thread was started because of one!
aforementioned companies actually paid people to design their circuits. use quality components, use one supplier of a certain component.
i reckon its safe to say (ive never done it!) that if you strobed ten HTs, not one would have the same advance curve or initial timing. there is just so much "slop" in the system!
im not arguing against jags cdi unit either. in a way, i do feel its masking what may be a fundamental flaw though.
now ive done this, im wary of assuming each HT will produce the same voltages, the same trigger point, or that the cdi is internally identical.
by allowing you to change the timing, you can nullify any inaccuracy in the stock system. therefore, better running.
doesnt fix the basic flaw
who is to say the newer style coils dont have 1000 more windings? that would make a higher voltage, and if the cdi hasnt been modified, then its too advanced, or if they have and you use an old coil then it will be way retarded and... until i burn a new coil out, im not finding out either!
maybe the flaws fixed. but then, i want my power for lights! red ones! white ones! those 4w mr16 LED replacements are amazing!
to the ratcave!!
gone.
