I got a new set of sonic springs installed!!! Talked with Rich @ sonic, he seems like a good guy, got my spring type figured out, the .9 and 4 days later the gs is better than ever. It took maybe 20mins to install, I did not touch the oil. The bike has 6300 miles so its in good shape. Rich did recommend 15w, but I just left it to see what it would do...doesn't rebound too fast at all!
Next install new bikeman drag bars, black, with a 3.5" sweep. Also new gel grips.
Its a new bike, bars are slightly smaller, like an inch,so that kinda slows the steering.
The springs do a great job! With the new position I'm more over the front and a little lower. The springs make all this work. Corners WAY better! There's this corner I go through a block from my house, 2nd gear, hard corner than jam it up to about 55 than hard on the breaks to a stop sign. With the old springs I really had to stay on top of it and just before the stop it would bottom and buck, no more. Its a new bike! If you have the old springs, replace em, you won't regret it!
