umberto:
I took my first welding class last night, and I learned a lot in just the first class. We actually got to weld quite a bit last night (enough to give me a welder's tan on my arm). The instructor told us we could work on personal projects if we wanted to, so I am going to take my bike with me to class Thursday night. I'll post some pictures of the progress.
I'm not sure how much the welder I use would have charged me to put the motor mounts on, but the class only cost me $130, and they provide, steel, tools, welders, helmet, and all the safety gear. Plus the instructor will be looking over my shoulder to make sure I have the welder set up correctly and I'm not messing up too badly.

Wow that sounds like a pretty good deal ,a bit of an education and all the access plus a "tan" to boot for a buck thirty .

I got a little bit more done on the bike today. I wasn't able to take it to welding class because I got home from work too late, but I was able to get the MX 31s mounted on the Tusk Impact wheels. Tusk doesn't make a wheel for the 2003, but the 2004 and up will fit if you use the stock brake side spacer on one side, and another brake side spacer (I bought a Tusk set) on the other side. (edit 1/5/2016: The two spacers will need to be adjusted a bit to fit. I started out on the brake side and adjusted it down until the rotor was centered in the brake caliper. I then adjusted the other side so the wheel fit. I ended up at around 33.5 mm for the brake side and 32.5 mm for the other side) The stock 2003 brake rotor won't fit the 2004 and up wheel, but I was planning to upgrade to a larger one anyway. I also mounted the kickstand and the KDX intake. I will be taking it to the class on Tuesday. I'll post some pics of anything I get done.

I took the bike to class tonight, and got the front motor mounts fabbed and welded on. I used a similar setup to the factory mounts, with one on each side of the frame. My welding instructor made a pass over my welds to make sure they were strong enough. I'll definitely do some cleanup on them this weekend.
Here are the mounts before welding:
After welding:
Next class I'll be working on the head stay. I'll post more photos after class.
