2002 FXDX upgrades
I would rebuild the front forks. Don't forget the other components. Everyone concentrates on engine power. That isn't the real advantage of a FXDX. Its handling is key. Make sure it is in full working order. A 10 year old bike should have the front forks rebuilt with heavy fork oil. Then make sure the rear shocks are in good shape. Either rebuild or replace with Works/Ohlins. Personally I noticed a great improvement upgrading to Work black trackkers over OEM.
Get some better tires when you wear the current set out. I run Metzler Marathon 880, but there are other choices
Also check the cam chain tensionors. If stock replace very soon. When they go it destroys engine parts...
Finally research old iron magizine articles from 2000-2003 on the TC88 and tricks for the FXDX. The guy I bought my bike from gave me a stack of clipped articles about various TC88 information and FXDX tricks/adjustments. It was an excellent read on how to optimize a TC88 and what issues are in the early models. Sometimes this info is lost since the newer bikes are different. TC96's have various improvements over the TC88 (and their own issues). Course this info lives on forums like ours

BTW - I do have many take-off parts from my FXDX since I am putting in a SE 120R engine. 44mm Screamin Eagle large bore racing carb with K and N intake car, heavy breather air filter, black Vance and Hines 2->1 classic exhaust as shown in my signature pix
We have a 2 into 1, rejetted carb and high flow filter. Not sure if we are going to do a 95" build with cams and heads or just spring for the 120R. However after reading about a guy who toasted a 120r which does not come with a warranty it has us thinking hard.
