Take a close look at the videos I posted in this thread

This was last weekend. You can see it lifts both fronts. When it is coming down, it unloads the rear tire about 10-15' out. If I had a shock that could slow the rise, it would definitely help.
The options I have are 1) try to add more add more power, which might carry the wheelie further and still have the issue or 2) slow the rise.
