For the KPX, the rear link is cast steel, and I extended it 1" by welding in a 1/4" plate on each side. Welds Beautifully with MIG.. nothing special required at all unlike Cast Iron. The front is capable of dropping a full 2" thru simple dropping the forks. I ended up with a 33" seat height.. maybe a tad less? Kick stand had to be shortened a bit. I'm dropping the bike for handling, not seat height. The skinny street tires on stock rims and hubs makes this a super fun bike for street. For the Plalidin (Doing a conversion to 17" SuMo wheels) the drop link is aluminum, and a tighter, more folded geometry that makes any link extension effects complicated. Considering re-drilling the shock arms, there is some additional space to lower the rear that way. Roughly an inch but unclear how this translates to seat height with the link geometry. The Pallidin can be dropped in the front only 1" thru fork drop. Anything more will require interior shock mods. But 17" wheels starts with a 2" drop in the front. The KPX is a wonderful bike, so easy.. everything fits well, and it's steel (easily Hacked)! Try 93 octane in it.. i think the EFI is advanced enough to recognize the good stuff and advance the timing. Seems to make a difference, although I haven't swapped back to 87 to test in quite a while. Good Luck!
