OK I did it. I started a WR450 only jetting Q's post. Now lets get things rolling with TT members that have actually rejetted their bikes. Lets build a knowledge base for the WR450. First thing I have noticed is the bike needs a leaner starter jet in the summer a 62 is working well for me right now to get quick e-starts. Try pulling in your hot start while having a richer starter jet and you will see what I am saying.
