Kieth, I think it would, if you don't use a vacuum canister. With the canister it would be redundant, I think.Kieth said:A friend of mine installs cruise control on Valkyries, he has discovered that by putting a check valve on the manifold of each cylinder that he keeps the vacuum at a much higher lever (since each cylinder only produces a vacuum every fourth stroke) these check valves keep the vac from leaking off. I have not looked at the FJR setup, could it benefit from the same type of plumbing enhancement. ????? :?
