Incredible build. You may want to look at the jetting on your bikes as Yamahas are notorious for being set very lean from the factory. Our TTR125 was a B!#@$% to start until I adjusted the needle to richen it up. I'd also check your batteries. My son's TW200 would turn over at what seemed like a decent cranking speed on the electric starter but not start. One kick would fire it easily. Changed battery and now no problems. Looking for another TW but won't buy one without a kicker. Don't know if there is a way to add a kicker to the WR's but I wouldn't have a back country bike without one.
