Secondary ramps breaking

[snowplow1984]

I keep breaking the little plastic like "ramps" on the secondary, went thru 2 sets now, 2 out of 3 break, leaving a single one to engage the helix. I replaced them all with new ones, same results... any ideas as to why?

Stock clutching?

Yes stock clutching, I just changed the Primary spring to BOP soft start and noticed the ramps broken again...

You are twisting the helix clockwise when preloading the secondary? The only time I've cracked the ramps is when the helix would slip out of my hands and clip the ramps and breaking them off. You have to be careful bolting the helix on too so you don't crush the ramp buttons as well. Are you using official Yamaha ramps? Aftermarkets, while cheap in price are also cheap in quality.

also check clutch temps if getting to hot this will happen

Yamaha OEM ramps??

I have found that the aftermarket ones are not the same material and break easy....

Not too much play in the bushings?

Factory Yamaha ramps, when I installed the helix back on I was very made sure it dint bind. How does one check play in bushings on the clutch?

i usually check them by rocking it on the shaft with the spring and helix removed.
