Bike is coughing into the airbox at 3500+/- rpms. Just had a full service done at the dealer. (Plugs, air filter oil....) and had the valves checked and at 30k they are spot on !!! So is it as simple as syncing the throttle bodies ?

welcome to the Vee. this behavior is normal....farting, coughing, spiting, popping yada yada yada and always between 3k-4k.

easily fixed with an ecu remap or the installation of an aftermarket power commander 3 or 5.

or, you can just power through that rpm band and live with it.

The first Vee I had a few years ago (2012 DL1000) did that. I sold that bike. Fast forward to March of this year, saw another bike just like it and bought it used from a dealer. This bike doesn't have that problem, but after I got it home from the dealer and started poking around, I found that it's got a PCFC (Power Commander Fuel Controller) installed. Didn't even know it had it.

In any case, this new bike I have doesn't have any such issues. Don't know if it's the PCFC that's preventing it, but I'm not gonna mess with it. PCFC is worth a shot, IMO.

Only had my bike a couple months. 03 v, prior the throttle sucked, and it was a bear to ride. Throttle surged and choked and popped, I was quickly regretting buying this bike. Purchased a used PC3 on Fleabay and instantly it's rideable and enjoyable. I literally grabbed the first map I saw on the PC3 map thread here and it's like a whole different motorcycle. Best $150 I have spent on the bike so far. I could not recommend enough.

I did sync my throttle bodies and aligned my secondary's and it helped a little. But did not fix it.

There are numerous threads about your issue. You need to get your ECU flashed to provide a richer low end mixture or get a PCFC to solve the problem. The numbered PCs will do it too, but unless you can get a used one, you will pay a bunch more for something with features you don't need and can't use. Vees of your vintage nearly all run too lean in that rpm range. The above is how you fix it.

Noob here, sorry to be late to the party.
Are the PC3s model specific, or will any PC3 work on any bike?

Thanks.

Not sure but I think the difference will be the connectors. It will have to have the right ends to hook to your wiring harness. You can go to the "dynojet power commander" web site. Might find the info you need.

Good info here. I find my 2007 to be pretty decent after syncing throttle bodies and adjusting the tps. I had not yet read about the secondary adjustment. What is that supposed to do? I seem to remember seeing someone state you can remove them? That doesn't seem right.

The intake air has to pass by the secondary plates first so they also need to be adjusted to get the most out of your tbs. Some say they run better out, others say the low end throttle response is smoother with them in. I think the main function is to limit top end speed. They close as the bike reaches 134 mph as the bike is considered unstable above that speed.

Make sure you have a decent throttle body sync, and that your throttle position sensor is adjusted properly (many threads on this issue, and you can use Google to find a video of how to do it on a TL1k).

All of that needs to be addressed before you hook a Power Commander to the bike
