HERES THE SOLUTION!
some aftermarket (stiffer) rear shock springs for my gts from:
www.scooterparts4you.co.uk
i installed them today.
all i can say is.
STIFF!!!
theyre really stiff, even on the first shock setting. if you have a pm pipe and have the problem of it catching on your crash bars/rear body panel then buy these!!
there is NO WAY it will touch the panel now. even 2 up with luggage on the first pre load setting
being me i put it on the hardest setting first, then went for a ride.
i nearly flew out of my seat going over a few bumps!!
oh, and it handles a little better round bends, its much more solid but now the front feels too soft!!
a front bitubo is next on my shopping list
