suspension help

recently inherited a '94 sworks full suspension mountain bike.. i think it was the first or close to it. components are '96. I am new to mountain biking and who like to try and make it happen this year. got a few concerns. weighing in @ 245 and my donator was probably 180 soaking wet.

1.) wheels are busting spokes, looks like the aluminum nipples are corroded and that is the point of breaking so i am going to relace the wheels because i believe the rims and the ringle hubs are in great shape. should i rehab or look for some new ones?
2.) suspension is screaming at me everytime i ride it.. hahah frnt forks are nice ( for the day ) carbon legged.. judy cartridge fork and i have been told don't try and rehab them buy new ones and the rear shock is Fox unit ( probably original) that says do not open. Does FOX rehab old shocks? i am old school even thou i am only 33 but i can do it w/ a manual and my tool box.

am i wrong to assume i can rebuild the rear shock and front forks to handly my weight

thanks

245 isn't all that heavy, thats what I weighed when I started biking however I was riding a hard tail bike with front suspension only. I'll assume by screaming you mean it bottoms out or bobs too much.

If the spokes keep popping you may be due for a new set of rims. I rode and abused a set hand built Mavic x 317's and never had a problem with a popped spoke or the rim going out of true. The rims were $140 total parts and build. Alternativly you could pick up a book and attempt to build them yourself. Could be a fun project for a rainy weekend.

Check your old fork for adjustment knobs. They will be on the top of the "legs" of the fork. Make them as tight as you can. If your fork lacks adjustment knobs then you may be best off looking into purchasing a new fork. Keep in mind that what is low end today likely outperforms cutting edge from a 5-10 years ago. Look into the Rockshox Dart and Tora lineup. Have an LBS install the fork, the required specialty tools required are far more expensive than the $30 (give or take) to have a professional mechanic install it for you.


I don't know about the rear shock, however if there is a warning sign not to open it then your probably shouldn't. Remember, that shock is under compression. Opening it sounds like a good way to loose an eye.

Opening the rear suspension on a mountain bike requires that it be caged, with a press or similar tool, like a McPherson Strut on a car. This can be done with a couple of steel flatbars and a courl of bolts that are lone enough. Not really a job for an uninitiated person though.

Parts tend to exit the bike at very high speed similar to what happens of you undo the crown nut on a strut without a caging press in place (Ask me how I know this and I'll tell you about how I stick a McPherson strut in the ceiling of the garage after bouncing it off the floor. )

Ok, now I want to hear the background story. Then I'll tell you about sticking a chuck key from a lathe into the ceiling of the Bradford Area High School machine shop.
