so it turns out that this is the same guy i got the bike from, bastard took the D&Ds off when he sold it to me.
Picking them up this saturday for 250!!! pic looks good, he asured me there are no scratches or dings, so we'll see.
wish me luck.

Reason

I bought my bike with D&Ds already on it and was told (and could smell) that it was running rich, and that it appeared a "good enough" jetting job had been done or at least attempted. It would also bog sometimes when blipped at stoplights, and was a **** to keep lit when donning earplugs/helmet/gloves.

I got my K&N and it made more sense to have it all done once, so I had it jetted. I don't have the knowledge, patience, or equipment to do this myself. $288 later, it doesn't bog or smell like gas, generally stays started, and the seat of my pants says it pulls harder up top. It sounds a bit different, too, the power pulses are more defined, more like a square wave whereas before it was more like a sine wave.

But, it's also got a nasty stumble (lean spot?) in the lower range RPMs. No tach so I can't say exactly where but it's disconcerting to say the least. Feels like I'm running out of gas, and it's bad enough that I'm considering spending the money to put the stocker back in and rejet it. Someone here, forget who, pointed out that the K&N doesn't have a fin in front of the air filter and the stocker does, and recommended installing one, so I might try that first.

And yes, the D&Ds WILL set off car alarms. They have a nice deep tone. A frequent visitor thought it was a minor earthquake the first time she heard it (through a few walls). It's pretty fun on the freeway but definitely has "obnoxious potential" on my ride home at night.

^^ that stumble means you are running lean on pilots...

either shim the needle or get a larger pilot jet...

i shimmed my DynoJet kit by one slot on the needle and it cleared up my low rpm stumble, hesitation (1500 to 3000 rpm)

I installed Yosh cans and Dynojet kit all at the same time and the bike ran great. I followed Dyno's jet sizing recommendation.
When I installed the K&N filters it bogged down at low revs something terrible. I rejetted per Dyno's suggested settings and the bike ran great. If your having a problem getting the carbs into the boots, use a little vasaline or your favourite lubricant on inside of the boots. They will slip on easily.
One thing to check before installing the D&D's is to check to make sure that the right header at the Y is not restricted. My header was half closed off because they did not trim away the pipe leading and exiting the Y connector. Use a flashlight, I missed it the first time. Idle was always a little rough and inconsistent when the engine was hot. It now idles perfectly since I opened up the header pipe.

But i read some folks say it should be there to equal out the exhaust flow?

Well.... it turned out better than i thought.
It turns out, that the guy had the exhaust on the bike for two years. the bike was already jeted for it. Whohoooo!!!!!
Slipped them on, went for a ride for a few hours... everything runs smooth, crispier.. more responsive. does not overheat, seems like same temp as before, idles better as well. Not terribly loud either.... all in all i'm happy.
He had the pipes online for a few weeks and no hits, as soon as i called him everyone and their mom started calling as well.... wouldn't be any of you guys, now would it?

Yeah, it sure doesn't take much to snap the threads off. I'm still waiting for the part to arrive. Glad I fixed it at least temporarily.
