Hi all, anyone able to help me out? Engine Turns over but won’t start. There’s spark at all 4 plugs, fuel being delivered at pots. Earth connections checked cleaned and tightened. Coil packs & leads resistance checked ok. Have you had this issue or have Any ideas? Thanks in advance

 

Might be late to the Party here but,
How many Miles has the Bike done ?
Are you able to carry out a Compression test accurately ?
If you have good Spark & Fuel that leaves compression as a likely suspect.
When you crank the Motor does the Fi light Flash ?
