I have a 1997 trx400fw and it's been sitting a while now but I am hoping to get it set up to plow this winter! After a good carb clean and starter rebuild I have her purring like a kitten but when I tried to take it for a rip I was only getting the front left wheel to engage....put it in reverse and she will drive over anything but not in the forward gears! Finally got it to the road and went through all the gears and it's now only engaging the front right wheel but still has great reverse traction! Any ideas??
