FYI, I have an appointment next week to replace the fuel injectors with the 25 degree injectors as outlined in the service bulletin.
It will be completely covered by HD. Ronnies Cycle in Pittsfield Mass has been an absolute pleasure to work with.
There is a service buletin for the 2006 TC-88. \\; It changes the 8 degree injector to 25 degree injector. \\; I have an EG and can't remember if it only applies to touring or all TC-88 engines.
