I got some extra stiffy springs, as 650,s i thowt are actually too soft and no only that, butt, the adjustable shocker damping just wont cope wid 650s as good as they could. {manufacturers say the OE are ok for upto 600 max , hence they cannae cope } as on full adjust for the 650s, ther still too much poppoising at speeds on bumy b roads fine on flat a roads. upto warp 1 Butt, ..floated too much for my lik,n at warp 1.3 on smoothe roads, as undulations get bigger at high warp,!!! So, got some double adjustable shocks med up, v v reasonable too, direct frae the manufacturers thee,s will be valved t,handle the stiffer shocks alot better than the standard adjustables Also, got the shock bodys an inch less, so as to give some suspensionee free play, as original type, that every yan gets is really no good if yer frunts lowered as 1 inch free play,untill bump stops come into play just aint enough meb,e sumet for folk t,consider whenst getting new shocks if yer cars lowered All this cos super stikkee tyres are noo causing havok wid me original set up got the springs, but shoks are a week t,mek, so cant say wot it,ll be like till I get the shoks an springs fitted ohh the joys of tinkerate,n !!
