I've got a 95 Gsr with TypeR cams I/E. Toda cams gears, Short Ram Intake, test pipe with 2 1/4" s/s HKS exhaust. I was running NGK platinum 6's and changed to 7's. Not sure which one is better to go with. Suggestions are welcomed. I've got a match up tonight at the track and need good responses quickly. Thnaks

 

I don't think you need the 7 range plug for your setup, since you still have stock compression. The colder plug may cause fouling? Either way, it probably won't make too much diff.

Thoughts?
