The main benefit of EI (of the type in question ) is only realized when
lean mixtures and or higher compression is in the mix . It is highly
unlikely you will ever save enough in gas and breaker points or gain
enough in performance to even approach the Harpoon asking price for the
EI .
The basic timing CURVE is still controlled by the same centrifugal
system the points utilized so that source of torque improvement is still
as it was for the most part .

Hi, all. I'm still cogitating on this electronic ignition thing, weighing the arguments con against any arguments pro that I can dream up, just hoping that somehow I can justify the expense... OK, here's my latest shot at expense-justification: I figure that this fancy electronic ignition, especially in cahoots with their high-output coil, will provide a stronger spark, which will contribute to more complete combustion, leading to slightly better gas mileage. This may be a fairly small improvement, but it's not nothing. Also, the consistently spot-on ignition timing for BOTH cylinders (given that one has good advance springs, which I do) should lead to an additional small improvement in gas mileage. My bike gets around 45mpg. Perhaps this new setup would bring that up to 46 mpg? Does that sound reasonable? Gas here (premium) costs around $1.75/gallon. That equals 3.9 cents a mile on my bike. Harpers price for the electronic ignition is around $330, as I remember. Therefore the 1 mpg improvement in gas mileage would pay for the ignition in 8,462 miles. Is my math correct? That is pretty fast savings, I think. So after about 2 years of riding I will be able to enjoy the increased power and gas mileage of the new setup, plus the reduced maintenance and increased reliability (I hope, but this last one is an untested hypothesis) for free. Does this sound convincing? Perhaps after I finish paying for my kids' braces I'll spring for an electronic ignition! -Mike (69 Ambo) ===== M.Jones, student of philosophy and religion at Temple University, Philadelphia, PA.
