TTR 230 Re-Jetting

For those who have put off the re-jet of their TTR230, just go for it! It's a breeze and the instructions listed in Project-Yamaha-TTR230---Part-3---Dirt-bike-breathing mods... is right on..
The only thing I would add is that some of the bowl screws are super torqued, and you may want to get a couple when you buy your jets. Also, get a bowl seal.. just in case.
The Yamaha OEM Jet Numbers are:
#130 Main Jet - 288-14343-65-00
#38 Pilot Jet- 43F-14342-19-00

Had it all done in about 20 minutes!.. Now it gets off choke faster, doesn't crap out when you get on it... and all the throttle, back fire BS is gone..

Now if someone can find a K&N filter for it... That would be nice...
