Afternoon all,
I finally got around to trying to diagnose an ongoing issue I have had since owning my Fazer, it seems that the bike runs great up to half throttle, as soon as I go past half throttle it starts 'spluttering' and missing. I originally thought it maybe something electrical, so I recently bought some bits from another foccer on her who was stripping his bike. I changed the Rectifier, coil packs & leads and finally the fuel pump/filter. If anything the bike now seems to pull stronger in every gear, but the issue at nearly full throttle still exists.
Im now thinking that since I had the bike, I fitted Motad stainless downpipes and can before getting the bike T&T'd, i did not however ever think of re-jetting the carbs to accommodate the increase in airflow. Would I be right in thinking that this may cause fuel starvation type symptoms at high revs/half-full throttle? If so, does anyone know how hard/easy the jets are to change?
Any help appreciated.
Greg
