I have a 2007 Gz suzuki with some kind of problem. The problem is when I get into fith gear the bike lurches, surges, cuts out ect, ect ect. It happens every 3 seconds in fith gear at any speed. It runs fine in 1-4th gear but when it is in 5th it is like a bkuckin bronko. i went through the carb and complety cleaned it and it was super clean when i did that (yesterday) I think it is electrical I changed the plug last week and no luck. Please if anyone knows what this is please let me know. Please help Rozzi
