I can't open the link. If they are WR500's STAY AWAY !!!!! they are slow, so slow you will be bored to tears. There is nothing to make them faster and no engine parts interchange. Save yourself the trouble.
I tried, air cleaner, scoop grate, ride plate etc, It got to about 20 mph with a tailwind

If they are mid 90's WaveVentures, I would say get em if they are in good shape with less than 200-300 hrs. on them. I got 3 of them, two 701's and one 1100cc. They are 3 seaters, very stable, very reliable, and alot of fun! If they are 701's, you could put an 1100 motor in it but you would have to change the pump as well, the 1100 has a 155mm pump, the 701 has a 144mm pump. My last one I got 3 yrs. ago, a 96 701 with 320 hrs. on it, runs like new. I only paid 1k for it. The 2 strokes are going pretty cheap now, but I think 4 stroke is the way to go, better gas milage and no 2 stroke oil to mess with.
