I have a 2011 RGC with Harley 19" front rim and 18" rear. Both tires are Harley Dunlop. I intentionally used Harley wheels and tires to avoid any problems with ride and handling. I also chromed the fork and when I did I asked the tek to replace the stock fork oil with Screaming Eagle oil. When I am riding at 70 mph or more the fairing starts to shake...the faster I go the worse it gets! I have dyna bead in the front tire, changed the front tire, going to change the fork oil back to stock today and see if that is it! Going nuts with this....anyone have any thought please? Thank you!

I would lean towards the steering head bearings not adjusted properly. You did have a lot of front end work done that required the front end to be taken apart so that is were I would start. I can't see how the fork oil would come into play with this issue. The next thing I would look at would be the Dyna beads in the tire you may want to remove them and balance the wheel with conventional weights.

I agree I don't see how it could be the fork oil. The steering head bearings are easy enough to check if you have a lift.

Would a front fork stabalizer bar help in this situation?

That should not be an option at first... he should try to find what the real culprit is before installing parts that hides/mitigate the issue without addressing the root cause of the problem.

Just imho of course...

Head bearings maybe. Dyna Beads. doubtful. I have run then for over 200k in different bikes with absolutely no adverse effects. Longer tire life and even wear is all I got as long as I stayed on top of proper inflation.

BTW the fall away should be set between 1 and 2 swings on your model.

Do one thing at a time, and pick the simple items first. High speed shakes are usually the fault of a out of balance issue. Remove the front tire and take out the dyna beads and have it balanced and re-install the tire and take it for a test ride. If the shake is gone that's great if not go to the nexted item that was changed or taken apart. The fork oil may cause a harsher ride but it shouldn't cause it to shake, if you have a bike jack check the fall-away and see if its correct if not have it corrected by the dealership or indy or corrected it yourself (its spelled out in your service manual). Everyone can make mistakes, check to see if the tires are mounted correctly and check the air pressure. I'm betting it's a tire balance issue!!!!!

My 09 shakes at 40 mph

My question is why does my 09 shake at 40 mph when you take your hands off the bars. I had given thought to a steering dampener but I have asked others and was told this was normal. Bike is bone stock. nothing has been done to it never dropped or wrecked. Proper air pressure in the tires. Need help

Now that is a ongoing thing with RGs.... I think there in noone here that does not have that. I asked my stealer to check into that... then he told me that he could, but I would have to pay for it, since HD has not come out with a recall on that. Then, as he said, it might move the problem up in speed, to where the shake would come later at 75 or 80 MPH...... But who takes their hands off the bars at those speeds. But then since he just got a RGCSE I think he might look into it now too.

Like others have said, get rid of the dyna beads and balance the tire wheel assembly.

probably the installation of the fairing... do it again from step 1.

My bike did this and it was the steering head bearing and the same for a few others I've run across. This is not normal don't let anyone tell you that. I had mine tested and adjusted at a dealer I trust for less than $80. If you have a lift there is a simple test for this in the service manual.
