Nozzles are brass which is very soft. Ti needles will wear them faster.Aguacate said:So is it better not to use titanium then? And does it wear out the nozzles that fast?
I don't really know anything about jetting and such. Are nozzles something I can just replace?
Don't bother with the stage 1. It is a waste of time IMO. Open your airbox and go stage 2. There is where you'll find better gains.Aguacate said:

You don't need to worry about which choice to make with Factory Pro, since it comes with a full range of main jets. Details about installation and tuning are in the FAQ.
The main reason I push Factory Pro over Dynojet is from all of the stories that I've read about rejetting with the two. There are a lot more stories of problems getting a Dynojet jet kit dialed in than with getting a Factory pro jet kit dialed in. Both can work well once you get everything right.ducpainter said:Scott is a fan of the factory kit. I have dyno jet in mine. It works fine.
+1 I dont have any FHE with Dynojet, but I can tell you that FactoryPro will offer you individual parts down to a single jet. They are VERY helpful and friendly (talked with the guy for almost an hour when I called to get 2 main jets).funkuncut said:I went with Factory Pro partly through recommendation and partly through experience with Dynojet. I don't know if Factory will supply individual replacement items but they've always been very helpful - I gave up with Dynojet because they were not helpful, and they have a policy of not selling any individual items, only complete kits. If you want to upgrade from Stage 1 to Stage 2 you have to buy a complete kit which duplicates most items - they made their choice, and I made mine. [thumbsup]
I'm also a fan of the FactoryPro kits too, for three reasons. Most importantly because dynojet use different numbers for their jets to everyone else including Mikuni - if the 142.5's you get in the FactoryPro kit are a little too small you can order 145s from any FactoryPro or Mikuni supplier - if you try to order a 145 sized Dynojet one you'll be quite disappointed (see pages like this one). Secondly because of the customer feedback about how helpful they are with regards to answering queries, and thirdly because of the nice touch of supplying allen socket replacement bolts for all the phillips head screws that are always such a pain when working with carbs that haven't been apart for a while - they even supply the right extra length ones for the two bolts that hold the throttle cable bracket on - it's not a big thing, maybe a buck or so's worth of bolts at retail, but it give a good impression and the feeling that they've though things through...ducpainter said:Scott is a fan of the factory kit.
Yup, I don't doubt it for a minute.I have dyno jet in mine. It works fine.
I very much agree with this. In my opinion thats the best reason to choose one over the other. In the absense of the guy doing the tuning having any preference though, I, like Scott, will recommend the FactoryPro kits...If you are going to work with a dealer on the fine tuning you might consider what they are familiar with.
It is very hard to tell if they are worn by just looking at them, unless they are VERY worn. I knew mine were worn after setting my float height and putting in a somewhat standard setup of jets and needle height for my intake/exhaust setup. Once I was at this point I measured what main jet I needed by doing some full throttle plug checks. I ended up needing to go up several steps to a 155. Next I did some midrange plugchecking and noticed that I needed to drop the needles down into the tubes (lean the mid-range mixture). I kept lowering the needles, but could not get them low enough to lean the mixture enough. (This is with the Facory Pro needles). At this point I realized that the emulsion tubes were worn.Aguacate said:How can I tell if the emulsion tubes are worn out?
I don't know when anything was installed or replaced.
