Where are your XT250's...let's see them.

Here's my experience with jetting the XT250 for higher elevations. I got the main jet part number from a parts fiche and then I tried variations of that number at www.ronayers.com to find the other sizes. These jets were used by a bunch of Yamaha thumpers in the 1980s and 1990s.

Yamaha part number - main jet size

288-14343-70-00 is #140
288-14343-68-00 is #135 standard main jet for 2008 XT250
288-14343-65-00 is #130
288-14343-63-00 is #125
288-14355-61-00 is #122
288-14343-60-00 is #120
288-14343-59-00 is #118

I ride from 5000ft up to 12000ft. On long hills and full throttle in 4th and 5th gear, my XT (with #135 main jet) had a bad rich stumble. I drilled some holes in the airbox, but it wasn't enough, so I got the smaller jets. I finally ended up with #122 main jet. I did not make any changes to the needle. The bike runs much better and I'm happy.

Hi Empanadaman,

the shot at Applecross, with the clouds clinging to the mountain was mine, all the others are by Docs (AKA Hammock Dweller) fair hands!

Great bikes for a great trip.

Sorry about that Reggie. They're all mixed up with mine.

Credit where credit is due, great shot.

I'm envious of you guys... after you get tired of riding around the UK you can just cross the channel and ride around Europe! Sweden during the summer sounds pretty nice... lot's of nice scenery I imagine!

Put a Wolfman Express tank bag on tonight. I'll take some better pics tomorrow during the day but you can see the reflective sections of the bag in this photo.

Thanks, that's the kind of info I was looking for. I still haven't received my jet kit from fleabay yet and I'm headed down to Merida for 8 days tomorrow but as soon as I get back I'm going to solve this problem.

I found this website that seems to have a lot of stuff for all kinds of carbs but none of the part #s match up with any part #s I have. If my ebay jet kit doesn't work out I'll email these folks and see if they can help.
