05 WR450F Zip Ty And JD questions
Posted August 02, 2005 - 11:08 AM
What is a Zip Ty jet and where can I get one?
What is a JD jet and where do I get one?
Is there a kit that has all I need?
At slightly above sea level and hot temps, what kit is best?
I don't think my dealer wanted to spend much time tuning it because I talked them into all they did as part of the deal.
Have any of you guys added an oil cooler to increase oil capacity and keep engine cooler? What brand?....thanks

JD kits and the Zip Ty screw are available in the TT store, but it only comes with the main jets, needles and clips. You'll also need some pilot jets, starter jets and leak jets, and maybe pilot air jets and main air jets, depending on how far into it you want to get. Get them at Sudco.com. I'd buy at least one jet (pilot, starter and leak) on either side of the combo you decide you want to use. For instance, if the D-base says to use a 48 pilot, I'd buy a 45 and a 50 as well. For the leak jets, I'd start with a 40 and a 50 since your stock one is probably a 70, and for the starter, I'd get a 70 and a 72 in addition to the 65 (???) that is there. Definitely do some research first, find out what you have before going out and buying jets all willy nilly.
Check the jetting database for some recommendations too. Indy did a great job detailing the jetting for almost every conceivable scenario.

Anyway, my suggestion is (and this is what I did) figure out exactly what all jets in your carb are before you start anything. Call this "baseline" and keep a log of it, along with a description of how the bike runs. Make whatever changes you like and keep a log of them as well. Yes, fewer is better because it will be easier to identify which changes cause good or bad results. However, in my opinion it is OK to jump straight to a D-base recommendation for your riding conditions because lots of guys have good results with them and you may strike gold on the 1st try. If not, go back to square one and start over taking small steps.
My suggestion to buy lots of jets before starting is so you're well prepared for the jetting experience. It sucks when you need to make another change and then have to order the appropriate jet. Plus, when you're jetting for the different seasons / altitudes, you'll have what you need. If you have everything you should be able to nail it in 1 or 2 days. It took me about a dozen test rides / changes before I had it.
Now, someone please feel free to jump all over me because I certainly don't know everything
