90 evo with the crane single fire ignition in it . the wife was riding and the bike start to run bad cuting out with no power then it would clear up and run fine. she had run down to reserve so im thinking she got some trash in tank so draind tank cleaned the filter in the pet **** and put fresh gas in .went for a ride today same thing sounds like it aint geting gas. could the coil be going bad. when the bike ideals it runs fine but under a load it starts run like crap .any ideals

thanks for any help

 

Is it a nosecone ignition? Is it the rear cylinder cutting out?

 

yes.

then the ignition it self is going.

 

if the ignition is going . is there a better one than the crane ? this one has been in the bike for a while.

 

I still like the Crane, but I use the external module. The heat in the nosecone takes out the module. Or replace the nosecone module and run it until the heat finally takes out the replacement.

I have never had a problem with an externally mounted module. You will have to do some rewiring to fit the external one.

Harley mounted some Sportser ignitions in the nose cone and the same thing happens to those ignitions.

 

were did you mount the external ? under the seat ? does it require and adtional wireing harness or just basic wireing.

thanks

 

What model bike? Stock bikes will have a mount that supported the stock external module.

You will need a wiring harness that has a plug that the Crane pugs into. Crane supplies a harness.

its a 90 softtail.

found a test for ignition . using a test light ground test light and start bike with bike runing touch light to termanals on coil front cylender and rear. should get a flicker or pulsating on light. front cyclender flickers rear there just is a constant light tech says if a constant light igntion is toast .

im waiting on my budy om metter to test coil to rule it out

thanks again

 

1990 softail the stock ignition mount is under the seat on the frame cross member. There should be two well nuts there for mounting it.

 

Must have sent 50 or more Crane ignitions back over the years.
Damn things tune easy, and run great..................until they don't.
