I need some help with fork tuning. I am riding a stock 2002 F4i. Recently I raised the rear ride height by placing a few shims between the shock and subframe. I did this to increase the swingarm angle to approximately 12.5 degrees. This made a big difference in how the bike turned and tracked through high-speed turns. However, this also created a problem under hard braking. Now the bike really tends to stoppie, so much so that I find myself braking earlier than with the stock set up.

I ordered and have in stock Race Tech springs and a Gold Valve kit that I plan to install after the next few races. In the mean time can I add a couple ounces of fork oil to minimize the nose dive and subsequent stoppies? Will that cause more problems? What are some other quick fix options?

Thanks.

Thanks Marcus, I sent you an e-mail.

Dave/Billy: Yes I respect Marcus' ability greatly. His idea about the swingarm has already proven to work.

Mine did the stoppie thing more often when I changed the geometry also. I just compensated by shifting my weight more rearward when heavy braking. You only have to slide back maybe an inch or so to compensate.
