Hi everyone,
2007 RWB VFR800, 33,000 miles, completely stock, no modifications
I will add my experience to this thread. I just tuned the starter jets on the four throttle bodies this past weekend. The bike was surging terribly, idle went from
@ 1,500 - 1,000.. I bought the Carbtune equipment, printed the manual and dug into this problem. After preparing everything and finally getting the Carbtune PRO tool hooked up, I started the bike. Well, looking at the Carbtune PRO tool, it was an OMG moment. No wonder this bike doesn't run right. Let's just say they were not in alignment. After about 30 or so minutes, finally got all throttle bodies to within .5 cmHG of each other. (Had fan blowing on engine ) The bike idles smoothly and twisting the throttle is very responsive. I am thrilled..

I also noticed that my bike had two short stacks up front and two long stacks in the rear. (Bought new, this is how it came from factory). Others had commented that this was not correct and indeed the manual shows a short, long up front and a long, short in rear. I changed them accordingly. I am thinking the worker doing the assembly just put short in front and long in rear.
Thanks for all previous comments and help,
