Upgrade or not

[niclpnut]

After reading several posts about coil relay mod, dyna/accel coil upgrade, dyna s/2000 ignition, I was considering doing some upgrading.


However, with the exception of the plug caps which are begining to crack, everything is working and testing normally on the 83 1100e

I know basscliff recently changed out his plug caps and is running stock coils, but would i notice a better spark with the dyna or accel coils, or would it be more of a piece of mind thing, having new coils.

Budget minded I would consider the the coil relay mod with aftermarket coils if it would noticebly improve idle etc... and save the ignition upgrade untill the stock one shot craps.

Or for $15 just change the plugcaps and call it good.


Thoughts?

Thanks,

Nic

Measure the voltage to your coils with the engine running. Compare the voltage from the Battery(+) to the Coil (+) O/W wire. If it is more than say 1.5V I would do the coil relay mod.

For a 12.8V battery that would be 11.3V ; my GS1100ED was a hard start at 10.5V.

Hot coils are always nice, but the DynaS is not necessary unless you have problems.

Thanks Pos, I'm at 11V to the coils running, with a fully charged/new battery.


If i can find the coils at a good price I'll probably go that route.

So how much of a voltage drop is that?

With hot coils and fresh motor 10.5V cold alot of times needed starter fluid. With the coil relay mod it is now instant on.

The guy we just helped (di&Khead NOS) has about a 2V drop with an 8V motor which remarkably did start, but he had huge power cutout at anything above 1/3 throttle.

1.6 V drop at the coils w/ 12.6 battery
