Liking the bike so far?

Pretty much the first 15-20 miles the bike was a pain to start. I am assuming it has more to do with the engine being new and not broken in. I went out this weekend and was a bit worried about stauling on the trails and the bike starting with the 'magic button'. To my suprise and happiness I did not have a single problem this weekend. I even let a fellow 2 stroker hop on it and he gave it a couple throttle twists(bad) and the bike still started easily after a couple turns.
Kind of long winded but if I were you I would;
1. Make sure you use the choke when cold starting and give
it a few squirts previous.
2. After it's started and is 'warm' don't use the choke(I
hosed myself on this one)
3. Just let the bike break-in and see if things improve.

Fully twist the throttle 5-7 times and hit the button. If yours was like mine it will fire immediately.
I once thought that the WR was hard to start but no more.

Twisting the throttle when it is off causes the accelerator pump to squirt raw gas inwards each time, washing all oil off the cylinder wall and contributing to increased cylinder, piston and ring wear. It will also contaminate your oil more quickly.
It is not like there are gallons of gas going into the cylinder when you twist the throttle. A small squirt is put in to the intake manifold and may get in to the head. It is really the same principle as a squirt of starting fluid. I guess if you keep twisting the throttle you could flood the bike and run in to the cylinder. All a few twists of the throttle does right before starting is get some fuel vapor in to the system. You then immediately hit the starter button and it instantly ignites. No gush of fuel is diluting your oil and even if a little would get through we all change our oil long before it would break down and have an effect.

Buy a 72 starter jet.
