Hello, I am new to the site as a member...I was having a problem reaching full shift on my 2002 ZR 600 EFI, I took the secondary apart, everything was stock except helix 56/50. I took the primary apart and found that the spring was not all the way seated in the spider assembly, I think it may have been coil binding. The spring is red and the rate was 145-300, weights were 52 grams (I belive stock is 53?)...Should I go with more weight???? 55-56??? Any suggestions would be very helpful.....Machine is entirely stock other then can and cosmetics...

In my opinion I would do just one thing at a time.... If you think it was coil bind by improper installation, fix that and try it, then if that doesn't work, then think about different weights.
