Re: Braking/Suspension issues - questions
Is it moving up/down like you are going for a stoppie or side to side sliding?
I'm not the most help, but I've been having to do my own research on my bike as my 600 was eating rear tires like nobody's business and the the rear on mine was giving me a form of vibration/lifting up that prevented me from doing anything with the bike until it stopped it....then I could turn in. On video it looked like I was riding a rumble strip, even though I wasn't. Some people called it chatter, I don't know - and I'm not good enough to do a stoppie! I paid the suspension guru at the track day organization $80 for a "set up" that offered NO help - so don't go with Superbike Suspension. Now that I know more it makes me mad he didn't help me and took my money.
I'm 125 pounds and had the stock 10.8 shock spring on the rear and had NO sag AT ALL, even though on paper he said I did - and I didn't even know what it was before; I just took his word for it, even though none of my problems went away.
As for tire wear, I was chewing up rear tires on a 600 way faster in 1 day than a 1000 could in 2 days on the old spring that SSB couldn't figure out why - from talking with the tire guy, I was "spinning" up the rear tire, for example, 10 inches, but every 8 inches the bike moved.
My research led me to a lighter spring (9.8) from Race Tech and then I had Thermosman at my most recent event go over it for a very fair $40.... where I still didn't have any movement from the bike whether I'm sitting on it or not

He mentioned a "collar" and to get it from Race Tech.
I got in touch with Race Tech just yesterday and learned I need 2 "collars" for the shock and that will allow me to set the preload... because right now I'm topped out as I understand it.
Not sure what year bike you have or what year bikes these collars are needed, but in sum Thermosman got it spot on. I'm finally on my way to some correction! I believe he's in Georgia but not sure what all events he attends. Good luck!
p.s. my bike still moves under heavy braking, but now it's more side to side but it's nothing that freaks me out or prevents me from riding the bike out.
