82 kz 1000 ltd project

hey everyone..i'm just about to tear into my kz project...i hear alot of bad stories about wobble..besides good tires bearings bushings and steering ..does rakeing them help? i'm a welder and i do a bit of body work too so i'm pretty sure i can do it ..i'm just wondering if its a good or bad idea to start with...i plan to lengthin the swing arm and just leave the shocks in their original mounts which should lower the back end some..maybe a 3 inch lengthen or 4 maybe not sure ..this is going to be a bobber...i love that kz 1000 engine tho

rake may help, but i would not rake it to cure a stability issue.that would be a lot of work for nothing. fix the cause first.
then,only rake it if u want that look.

thank you ..that saves a lot of work...but what is the cause?
