Its quite common for the ATV racers to change from 3:2 to 4:1 to minimize the effects of bumpsteer as well as make the machine easier to steer. Everybody from B class on up has usually made the change. And we don't necessarily want to add width as its typically 48" limit. See this link for an explanation:http://www.exriders.com/archive/topic/300433-1.htmlAs for how to check, remove shock, lift front end and move the arm through its travel with tie rods connected and watch from above for change in toe. Correct??
...that will change your scrub radius and could make your steering feel heavy........
..extra scrub radius will make it turn harder...
Control scrub,control scrub,control scrub,control scrub,control scrub,control scrub,control scrub,...................................just cannot be stressed enough.
Scrub then causes wheel whip where you hit a bump and it yanks the wheel to that side hence why some people think that is what bump steer is. So when everyone is saying you have too much scrub, that is the same thing the quad guys are fixing. They are just not using the correct terminology.
This is not correct. Tire width has nothing to do with scrub radius as scrub is determined at tire centerline.
correct. Even the taller tires, the KPI looks as if its still too far inside. More KPI or 32" tires?
Honestly, I feel you should just live with it ,change wheel offset to help out for now and in the end get a "real" front suspension design in place in the future.
Thats what I was figuring.. Just wanted to see if there was something simple and easy and obvious that I was missing... The KPI on the single a-arm though is not a quick fix And did I understand it correctly, that the top of my spindle should be angled in about 1 - 1.5" more to get a more correct KPI?Thanks for the education too between scrub and bump-steer... I started educating my friends on that one.. Its amazing how two niches of off-road riding call the same thing something different..
