With inpiration from Grimm and Joker, I am converting my wife's Sportster to a Frankenstein 34" trike and plan to install a Seeger Chopper wide glide kit.
The Frankenstein kit was well designed and easy to install however I was surprised at the low speed front end wobble from 10mph to 40 mph. Wobble went away at faster speeds. I increased the front fork bearing pre-load to take out the fall-away and that helped some. Frankenstein rep said they had heard of this issue, but had not seen it themselves. They also stated that the 5 deg EZ steer would increase the front end stability and make it easier to steer. Given I am going to try the Seeger Chopper kit, the EZ steer is not currently an option.
Wondering if anyone else has had this low speed wobble and could offer corrective action. The front tire is a new metzeler.
I believe the Seeger Chopper kit's increased rake will assist in reducing the wobble however, by design (reduced offset) the Chopper front end only slightly reduce's the stock trail and therefore the turning force to "steer" may still be too much for my bride. Any thoughts are greatly appreciated.
