As far as break in. The 4 strokes have a longer break in period than 2 strokes. It should be outlined in your owners manual.
Congrats on the new ride and good luck!!!

My break in is 10 minutes long. I ride around the block for a while and then change the oil and filter.
After the first ride I check nuts and bolts and change the oil and filter again.

anyone have pictures/dimensions of the carburetor stop?
My throttle stop was 19mm exactly. That was the shank of the bolt, the allen/head is not included in this measurement. Start a little bigger and then grind it down as you look in the carb to see when its wide open.
Like so many other post, that have already pointed this out; you are going to have to change your jetting big time, when you've done those mods.

My WR's air filter was dry as a bone out of the crate. The exhaust was leaking in two places. The rebound on one of the front forks was at 8 clicks and the other at 7. Oh, and the tires were at 35 psi.
I believe the manual recommends one hour at less than half throttle for the break-in. I'm a little anal, so I changed the oil when I took it out of the crate, then rode it for 10 minutes and gave it an oil and filter change. The oil had lots of particulate matter in it. Glad I didn't subject the engine to a whole hour with that oil. Sounds like a lot of extra work, but I think it will increase the life of your engine.

My question now is regarding de airfilter box. There is no lid yet the battery blocks quite a sustantial part, I also noticed that different form my WR426 the right side panel has no opening to put your hand in to lift the rear end of the bike (and also increase air flow) I found some info on this side about drilling holes in the right side of the airfilter box. To which extent this is really necessary? And would it be better to "open" the hand insert of the right side panel??
Other question, how long can the bike stand still and still have enough battery charge to start it?
What is the right way to start this bike? Is it better to pull the hotstart lever everytime, can I start it without causing damage in-gear with the clutch lever pulled?
I am still breaking the bike in and haven't jetted it 100% yet , though it felt like my YZ time WR426F with WhiteBros E-series pulled harder. Is this true, and how much comes due to timing and how much is a result of the stock (uncorked) WRpipe. I have a friend with a 2003 YZ muffler and power bomb curve for sale, do you recommed it?
I notice that the bike was geared 14x50. I geared my WR426 14x43 which is great as the bike has plenty of power and has to shift less and a longer haul and top speed. The 450 can also be geared 14x43 and still feel strong or is the primary transmission ratio of both bikes different? Thats all for now, thanks!@
