Hi, British newb here & newb to trikes. 1st post & need some advice.
My (yet to be ridden) trike is a Yammy Vmax 1200 (1998) with home built soft tail swing arm & english rear axel (ford escort mk1), compomotive 15" rim wheels. Bike section is stock Vmax as far as I can tell.
It had problems with the rear home built swing arm & shock absorbers when I bought it. I've done a lot to sort that out.
It had the original 1998 stock rear shocks on & they were spent & I've replaced them with some YSS eco lines but the springs seem a little soft. I have yet to ride this - still putting it back together.
I have checked the YSS spec's & their Vmax replacement coil over shocks progressive spring rating is 25-35 N/mm & mine have 20-30s. I know I should have checked 1st but that's hindsight (& ADHD).
My question is, in general, should I be going for the same spring rating as the original donor bike or something a bit beefier?
