OK guys, I got a set of SLP high RPM pipes for the Ultra, and SLP doesn't make their needles anymore. SLP said the problem was that nobody had a needle with the curve they wanted, so they made their own. I'm curious to know what you guys are running and what may be some issues/concerns with running the stock, or other, needles. Going on a long shot: if anyone has a set they would like to sell, I am interested lol.

Thank you all, your time is much appreciated.

Well I know I can probably get away with the stock ones, a lot of people run them. The problem is I'm probably gonna need the curve of the SLP needle to get the fuel at the right spot in the RPM range. I just don't know how much different the SLP one is from stock and how much it can affect performance. Like you said "hilarious fast when set up" and I like to get them set up just right [8D]. Thank you, your experience helps.

SLP needles are the best choice if you can find a set. Using the stock needles you need to change the needle jets(nozzles). The stock jets are way too small.

psi made a set of needles too. they are the way to go to set up right. ultras had a mid range lean spot. but its not really a problem, just go a size bigger on recomended jetting. i always tend to error to the safe side. but yes both companies made there own needles. ultras are a rare breed and yes very fun once set up. no its not a necessity to have htese needles.

are you talking psi pipes or needles. because the slp pipes are actually proven a few more horsepower. im a psi person myself i think they sound alot better, but the slps are dynoed at more horsepower.

I thought he was talking about needles since that is what my post is about lol. Now that you say something, that is a good question.

Well I think I am having a few sets made by a place in Cali that does a lot of race bike work. I have heard good responses from people who had needles made by them. Let me know anyway though. Thank you for your help, it is much appreciated.

I didnt notice much of a defference between the 2 needles either. I changed them anyways and the ultra seems to run fine.

slp needles have 5 e clip rings plus a dummy ring, so it looks like theres 6 rings for the e clip. psi needles had 4 grooves for the eclip. ill try and get a pic of the 2 sets but never had any luck with close up pics and my camera

I had SLP send me the prints for their needle and the dimensions are quite a bit different than that of the stock one, or even a close Mikuni one. It is really hard to see these differences with your eye, but the profile of the needles are different.

Yes snake, they're supposed to have them finished in the next week or two. I'm having them made per SLP's prints from titanium because of its better wear properties, and its also light.

Yes, because those needles sure are heavy, especially since you gotta have 3 of them! How much is it costing you to get them made?

Wanna share that spec sheet you got your hands on?
