Yamaha - Jet, Pilot, (#38) - 43F-14342-19-00

My TT-R230 had been running lean, like it didn't idle without choke. So I went to forum, and these jets are their suggestion (#38 pilot, 130 main). Installation was real easy. Took the seat, and gas tank, loosened the air box fasteners. Then took the carb off (I didn't take throttle cable off, so the carb is hanging on them). Then changed those jets. Since the bike is old (2007 model), I also replaced the float chamber gasket, and glad I did it. Old gasket was almost cracked and breaking apart.

End result. Awesome! Now idles perfect without choke, and I can even lift the front so easy. I didn't expect it's got this much torque.

Highly recommend these jets to TT-R230 owners with similar issue.
Thanks 2WheelPros!

2005 Yamaha TTR 230: Bike wouldn't start after sitting for a couple of years. Cleaned out the carb and changed the pilot jet from #36 to #38 so it would start easier and warm up quicker. Bike is jetted way too lean from the factory. I had previously increased the main jet size. Bike runs fantastic now, and the warm up time drastically reduced!
