hey guys ive got an issue with a swinger 3-way. i got it on a brand new giant vt3 frame. i weigh 170 lbs. ive been putting 150 in the main spring and 165 in the spv side. after every ride, 2 so far, ive checked the pressures to find the main spring has held pressure BUT, the spv side has dropped to about 75 lbs. what do you think? why would a brand new shock leak so bad? could it be my pump? thanks for your input-brian
