I have had my bike for many years 5 plus and not an electrical issue whatsoever.
I now have an issue with the coils that seem to be overheating when they didn't before.
Issue:
I noticed the coils have never been stock ones, they are slightly too big and are only connected
by one bolt to the frame. (I am thinking this is the issue here not allowing heat to dissipate with only the one frame connection. )
This however has always been the case and they have only started to overheat in the past month.
History:
4 weeks ago:
bike went onto 2 cylinders and ignition fuse blew
sorted a load of connectors and put in correct fuses.
Noted the regulator was one that had a sense wire and i had taken it off ! put back onto the live rear brake wire
2 weeks ago:
bike went onto 2 cylinders - no fuses blew
Piranha Ignition box very hot and smoking ....
Stopped for a while and managed to get back 30 miles on two cylinders and no further issues.
lh coil showed 1 as resistance - clearly shot
So assumed the ignition system was at fault and got a new one.
week ago:
new elec Ignition system fitted and another coil (the same) fitted (3.4 ohms primary)
- boy does it go better though and better on fuel by 10-20 miles per tank !
Noticed the coil connection bolts to frame getting very hot - remember i only have the one connection as coil to big)
I swapped round the connector bolts to near the primary end (they has always been on the secondary end) to dissipate the heat and bike has run fine but
when i removed the tank i noticed the plastic had slightly melted near the secondary end of the coil ?
It still runs mind !
Do you think the issue is the coil dissipates heat via the frame connectors , there are two of them !
Any thoughts be useful - can get stats instantly to assist if anyone needs more info.
