Help needed vee miss

My 2005 1000 is popping in the air box and missing when you pull out up to around 4.5 to 5k rpms then takes off in all gears. I changed plugs, front was clean rear was a little carboned up. the boots on the intake are on, I also put long lines for the vacuum if I have them synced. I used seafoam, and now Helix. It seems to run a little better but not much. Former owner put an inline fuel filter, I am going to change that but do I get the throttle bodies synced or adjust the tps. Or am I missing something else. Thanks for any help.

The popping sound via the air box sounds like fueling. There have been cases where a throttle body boot has come adrift,,2990.0.html, and need to be reseated. If these check out ok, then do a fuel flow test,,3981.0.html?
For the steps on the throttle body sync,,10839.0.html. Some additional reading, on the secondary throttle plate adjustment,,6477.0.html

While you say the throttle body boots are in is quite common for them to appear to be in place when in fact there is a slight leak in one or more connections. Your symptoms point to that, especially if it just started doing it. You have to take the tank off, and very carefully inspect them. Some like to remove them, clean the area and put sealer on them. At any rate, you must be sure these are perfect as anything to do won't help much if there is a leak in these.

Once you are sure the boots are good, then checking/adjusting the TPS so it raises at 1700-1800 rpm. Raise idle speed to 1250-1300 rpm. The LAST thing you do is the throttle body sync.

I suspect it will be much improved after that.

Fueling can be an issue. But this won't be the fuel filter. Fix the basics first then worry about what is left that can be done.

I did the tps check and it looks like it needs adjusted. It started in the middle at idle, gave some throttle and the bar raised around 2k rpms. At idle it stayed at the upper bar. I will try playing with that tonight or tomorrow.

Well I solved the problem. It was the rear fuel injector, I got one on ebay used and bike runs great. I am going to send out the bad one to get tested and clean, found a few that do motorcycles for about 20 dollars. Thanks for the help.
