well, i was pretty discouraged by the prices of all these options, so i decided to just put fresh springs into both the primary and secondary. glad i went this route, cuz once i took them apart and inspected everything, i found some weird stuff....
although i was looking at the primary, since the engagement seemed odd before, everything seemed to check out ok. i ordered a new primary spring anyway, but the old one is still holding the same length and feel as the new one. it wasn't that long ago that i had the primary rollers replaced, so i was happy that everything else seemed to be holding up too.
the secondary however, is where things got haywire... first off, the plastic ramps were both loose. took them off, and they aren't anywhere near being the same size/profile. it's almost like one of them got changed out to a different style, and the other didn't. the new ones are identical parts.
i ordered the same spring, but comparing the old one, i can tell that it is sacked out. sits way lower.
not only that, but there is supposed to be a rubber spring pad at either end of the spring, but one of them was missing, so i got another one and put it in. add it all up, and i assume that i'll have a lot more pressure in the secondary, which i assume will improve my bottom end/throttle response/backshift. maybe even the engagement, if the secondary wasn't fully shifting back.
i changed out the rollers while i was at it, but they turned out to be identical in size, with no signs of wear. probably didn't need to do that, but whatever.
hard to tell, but this pic has all 4 springs in it. the primary's up front are the same height. secondary's in the back aren't.
here's the difference in the ramps. odd.
