Hi..little d...The bike is about half way way through...have made most of the major parts...forks - frame - tanks - seat .. made wheels up from Honda c125 hubs and new 21" alloy rims and spokes to suit....using dunlop 402r tires this will give me about 28" diameter wheel...frame and forks need to be braze welded ...tanks are all tacked together and need to welded up...every thing needs to be assembled to make sure it all fits before I weld it .....BVX

Hi Racepres....I 'm no expert with springs ..I always use the spring works to make or modify my springs.... you should be able to cut it and temper should stay in it....its when you heat to bend is when it changes to tempering process....there is a sequence of heating and cooling in oil that needs to be followed when bending or changing the shape of a spring and retemper it...often someone will reverse the eye on a spring and it will snap off from being britle....they use different heat temperature to bend and then temper...BVX
