A forum for owners of Yamaha TTR250 trail and enduro bikes!

Hey Everyone,

I know there is a ton of info (and confusion) about jetting, size variances between manufacturers, and what part numbers are available in OEM. I've been emailing back and forth with Jetsrus.com, and let them know the Mikuni jets they show on their website as appropriate for the TTR are actually the wrong style of jet (though they may work). He informed me that they failed to update their reference page, but they now have tekei compatible jets available that will match exactly with no converting necessary. They are actually Keihin jets. I'll put this on the main sticky as well, but wanted to make sure everyone saw it. The info is below. Happy riding!!

Here is more information that may help when rejetting,  we now have the main and slow jets for the tekei carb.  We failed to get the page you ordered from updated but here is a link to the main and pilots we carry for teikei.

 It is very helpful when folks like yourself let us know what jets they need as we will get them made if there is enough interest.  I don't think many know that we have the teikei jets.  Also if you are in need of other jets here is a link to most of the jets we havehttp://www.jetsrus.com/FAQs/FAQ_identify_that_jet.htm 

Here are the correct jets for your bike, if you agree let me know and I will send the 42.5 to you http://www.jetsrus.com/a_jets_by_carburetor_type/jets_teikei_slow_3U.html
