give me a shout if you need anything. i would recommend adding a yfz inner spring along with the softer cannondale spring to raise the engagement speed. the yfz spring can be bought from rekluse.
Great question. I am not real sure. I just know that it was catching at idle. 2-2300 rpms maybe With the yfz spring it bumped the engagement up to like 2500-2750 rpms. This was a huge problem dead engine starts in the woods.
