I am working on a small oil cooler modification project over in the Rhino forums and since the Wolverine has a similar unit, I thought I would share the mod here as well. We have been pioneering heat exchanger design on off road desert race bikes for some time now. And one of the projects I worked on with BMW/Husqvarna was these exchangers for Dakar rally race bikes. Adapting these to Wolverines would be pretty simple actually and I think I already make the hose fittings to make the project easier.
Here is the current configuration of oil coolers on the Wolverine.
Here is the oil cooler configuration on Viking side by sides.
The oil cooler is a radiator coolant/oil heat exchanger and is far more efficient as well as safer from debris. Also, not having to pump the oil all the way to the front of your vehicle and back before it is delivered to your engine's oil galleries is a huge plus. I am not exactly sure of the positioning of the Wolverine's oil cooler, is it in front of the radiator?
The Yamaha Viking oil cooler is quite expensive, however, I have found an inexpensive replacement on eBay in the form of a Kawasaki Ninja cooler.
I have ordered my Kawasaki oil heat exchanger and will continue to follow up on the project as I progress.
Here is the mod posting/progression in the Rhino forums.
