[BEFORE]when the bike is at a speed of about 60mph for a Mins or 2 she started to splutter/misfire.like she was running out of fuel.
After trying a few suggestions what seamed to solve it was removing air filter[k&n type]so replaced with new standard.ALL SEAMED WELL


ON the way back from our gathering on Sunday we went a faster route.And the problem returned.


But this time moved to 80mph.
When we returned to country roads with speeds going up and down NO PROBLEM.
ANY IDEARS?
