2007 ec 250 looses spark and cuts out after riding for around an hour. Anyone ever had this fault?. It starts after jiggling about with coil wire and unplugging and re plugging cdi connector. Dont no if this is a coinceidence but spark appears seems quite weak and it starts for another while..
Heres a bit of background info
Bike had a really bad missfire before after it got warm about 10/15minutes, so tried a friends coil and the wee black box thats bolted on to the coil..cured problem raced for 2.5 hour without a problem....so ordered a new coil
fitted it and ever since the bike stops every hour with no spark. Checked all wiring opened loom and checked all wires and connections / coil earth etc. Could that wee box bolted to the coil cause all this problem? Or is there just that many problems maybe it lies elsewhere??
I am trying to eliminate the fault quick as i have entered a race but its so time consuming as the bike will run for about an hour perfect.. any info would be a help thanks..
