high speed vibration in csc trike

Hoping someone might have answer. Just got a 2016 Harley Davidson Triked with a 2018 csc Daytona kit 6 degree rake has all the extras from csc.This is my wifes bike. I took it to the dealer to get the BAS sensor swithed to trike cause it was shutting the bike off in hard right turns no problem had them change it over to trike mode. On the way there I took the bike up to 70 and noticed a vibration and it went away after 75 ok simple tire is out of balance so I thought. Anyone that knows Harley they charge $125 to take the front tire off so I had them put a brand new tire on and balance. Figured that would cure the problem well it didn't still have the vibration at about 68 to 75 mph. I checked the steering head bearings and the wheel bearings all ok there so now I am scratching my head anyone have any thoughts?

Thanks Rhino 2 just had a new tire put on I would think that a out of round rim would not balance. Might try dyna beads to see.

Rebalance rear tires. On a trike they can make it feel like the vibration is up front.

Just a "thought" BUT this happened to me, until I met two board members for lunch last week (thanks Doug & John) BUT m[U]aybe you have too much air in your tires [/U]like I did.. We removed just 2 psi of air in each rear tire and now it rides very smooth..I'm a very happy boy now! :clapping:Thanks John and Doug

I'm amazed on how just 2psi's make, on the smoothness.............

High speed vibration update

I would like to thank everyone for there input into my issue. So I called CSC to find out the what they recommend for tire pressures which is 25 rear 36 front. Well front was right when I checked the rear they were 32 lbs so I let some air out and had rear tire rebalanced and threw some dyna beads in the front tire and I have to say it rides like a whole new bike. Vibration is gone and rides like its on air. problem solved thank you everyone. Happy riding:clapping:
