I'm getting ready to buy fork oil, Progressive springs and the All Ball bearings for my 1300C and have a question about the oil weight and amount. I weigh 250 and generally ride solo, what weight oil do people recommend? The manual list how much oil, I think it was 15.8 oz plus or minus some small amount AND to measure the height of the oil with the fork compressed and in a vertical position. Is the height of the oil more important than the amount? Is that 15 oz for each fork or total?
