I'm looking to swap the stockers with the HD Chizled Lo bars. Dealership is telling me I also need to install a new twist grip sensor. Just want to see if this is necessary before I spend more cash. I've been quoted 5 hours of labor at 90.00 an hour...Wowsa. I never knew a bar swap would be so costly, so I'm double checking every add on I'm told I need. Oh, and they said I'd most likely need new grips, since the stocks may be damaged during the install. This bar swap get more expensive by the day...they better look and perform well for the money.
