Hi Graham your bike comes with progressive springs as standard, so they are what the bike was designed to run on. I have Hyperpro progressive springs in mine and Luke R6 shock kits. Had problems with mine to start with , spoke to Luke and he'd spent a lot of time helping me out, but the front settings back from Hyperpro settings to the Yamaha standard settings and very very much improved, will now run and see how I go.Do not give up, I think you're mechanics have got some thing wrong, speak to Luke he really knows his stuf and I am sure will help you out. Good luck.
