I've been thinking about figuring out a way to decrease the amount of internal pressure inside the crankcase of my '08 T100, and my son's '02 904cc Bonnie. Both bikes tend to blow excessive amounts of oil through the breather tube.
The latest issue of Cycle World and Motorcyclist magazines both show photos of Norman Hyde's "Hyde Harrier", and in both magazines you can see what appears to be an external braided hose coming out of the upper side of the primary cover. I have to assume it's there to allow the engine's internals to breath better.
I'm thinking that a low-buck solution might be to take stock oil filler cap, cut a hole in it (say 1/2"), weld a 1" 'tube' over the hole, making sure that the inside diameter of the tube is the same diameter as the hold in the cap, install a 1/2" diameter hose over the tube, clamp it tight and run it toward the rear of the bike.
I can't help but think that increasing the cc's in a Hinckley Bonnie motor, or running the dog-sh!t out of one for extended periods, causes the internal pressures to blow excessive amounts of oil out through the stock (small) breather hose.
Any thoughts or comments on whether this is a viable solution to a simple problem, or is there something already out there that will fit the bill.
Thanks ahead of time for your words of wisdom.
