Yamaha SRX OR VIPER
speed ring kit
primary clutch upgrade
This is a speed ring kit. It is made by speedring inc. It it used to make the clutch go in to over drive and achieve awsome top end speeds with out losing botom end horsepower.
Has anyone tried this thing?
Does it really work?
I saw it on eBay, but did not bid on it thinking it was just another one of those give me money and bolt this on your sled and you will go 500mph "promise" things
But I am curious if it would work on my stock mountain viper since it's geared pretty low and has poor top speed.

I have never tried one, but heard they don't do anything. Although mountainmax has the speed shieve and says it helped him, so who knows

won't do shittt, the first thing to stop you from shifting out is coil binding in the secondary, period. make your center to center closer, and get the belt as high in the secondary as possible, with a deflection of 1.5 inches, add washers. Tune from there.
