Sorry, no time for reading all the threads again, but I'm 230 lbs W/O gear, riding a 2008 450 EXC-R. It looks like I will pass on a re-valve for now for my 2008 and go with .48 front springs with new fluid at Noleen's recommended levels/wts and i think he said a 7.8 rear straight rate spring. From my reading here, I decided to try the straight rate first. I'm a fast intermediate desert and mtn/woods rider, dual sport rider. Will this be fine??? I've spent a ton of cash on this bike already, and I am hoping I'll be alright without the re-valve, but, if I have too..... It seems a 7.8 straight spring is hard to find right now? Who stocks one right now? I'm using Noleen in the high desert hesperia, california.
