Does anyone else have TriWing Industries conversion? I am pretty sure there is at least one other on here. I would be interested in hearing about your experience with them. I purchased the TriWing for several reasons: 1) Build. Only two manufacturers I could find would sell directly to the end user & I wanted to build it myself. 2) Looks. I think it has good lines that mesh well with the Valkyrie Interstate 3) Trunk capacity. Had the larger of the two under consideration. 4) Gearing. TriWing agreed to supply a 2:73 gear ratio, which, together with the 215 65R 15 Altimax RTs, lowered my RPM by approximately 300 across the board in 5th gear.
The fiberglass portion of the kit was very well finished and needed only light scuffing prior to painting. Even the underside was gel coated, which saved quite a bit of blood and pain during the install. The cut out for the seat was a bit large and required some "trim".
The fitting of the driveshaft was complex and problematic, but not impossible. Installation/removal requires the rear end to be disconnected from the swing arm. There really must be a better way to build it and Jim (one of the owners) & I have discussed some options. I don't know if they will implement any of them.
The unit has 21,000 mile on it now. The pinion nut on the differential was either not properly torqued or was previously used, and came loose after 450 miles, effectively destroying the ring & pinon set. TriWing shipped me a replacement rear end at no cost. I also had a u-joint (theirs, not the Honda one) fail and an axle seal. While they paid for the parts, I think this indicates some lack of quality control on their part.
Overall, I am still happy with the unit. If I were to do it again I would probably buy the TriWing again because of the flexibility of gearing and tire/wheel choices. This was the only company making a conversion for the Valkyrie who offered any choices in this area. I would also incorporate the drive shaft mods into the unit before installation. Having said that I would also have it installed by one of their installers, so any warranty labor would also be covered. Stan
