Hey Cowpuc, I apologize in advance if I take this thread a bit off topic but I wanted to touch on the extent I went to, to try and solve this issue with the overheating stators. I actually machined ONE "modified" stator cover from 6061 T6 Aluminum Billet. It increased the oil volume in the pan by 1.1 quarts and moved the face of the stator cover almost 2 inches away from the stator. It worked great and allowed me to put a stator that came close to 100 amps of output in my 87'VR! You would think that this would be a win/win for the First Gens. Heck, you could run a Toaster Oven on your bike if you wanted to! Well the problem was that cover machined from billet would cost $800.00 (MY cost for material and machine time) not to mention the 100 amp stator was another $250.00. (again, actual cost) Historically speaking, I have found that First Gen. owners are a bit "light in the pocketbook" when it comes to spending money on parts for their bikes. After the excitement of solving the issue wore off, I found myself wondering how many First Gen. owners would actually spring for a $1200. stator upgrade. Of course the answer was "NOT Many"! So the tooling and fixture went into a box I have set aside for projects that I would NEVER be able to sell to the general population of First Gen. owners, and I stopped getting High Output stators wound by my local vendor. I went to a lot of trouble to offer a solution to the low amperage stator offered by Yamaha, only to find out that there is no way I could sell the darn things! I now fully understand why Yamaha puts such a wimpy stator in our bikes. I wanted to share this info with the community, and to let you know how much this broke my heart NOT to be able to offer this upgrade to solve this issue. Rant over, now back to your regularly scheduled programming!
