Electrical Guru ,advice Please 91 Daytona 1000

If the bike has been sitting around doing nowt for a while, then stick a goodly slug of Redex, or similar, in the petrol and get the engine running to pull it through the carbs. It may just be that there is shit (a technical term!) in the carbs that you can't see. That would cause poor starting and running. I know this to be true!!
I've dealt with Sprint Manufacturing a few times with no problems, so no worries there - hopefully.

 

May be loose connections in the leads try swapping leads and plugs?

 

I would suspect the coils. But then again, I ALWAYS suspect the coils. ...J.D.

 

For me it's always the butler under suspicion

 

Can't help with the techno-electrical stuff but can heartily recommend SPRINT MFG. - good people to deal with and very knowledgeable about early Hinckley bikes.

 

The trouble with modern coils is that they can crack and start to break down under load check the LT resistance and report back, if the leads are built in resistance type like then they should be reading around 10k oms and again if they are of the carbon type they are also prone to breakage if they are replaceable then try some std copper core and see if that helps.

This is all presuming that the fueling is OK as if its a combination of the two you will need to eliminate one of them first.

 

Even clear over here in the western I have used Sprint Mfg. Only problem is shipping cost across the pond gets pretty steep. There are times though, I cannot find what I need elsewhere. All depends on where you are located. ...J.D.
