    Default Changing sprockets on HD trike

    I have a 2013 HD Ultra Limited with a Roadsmith trike kit installed. The problem I have is, it is a dog just starting off with myself and wife onboard. I am a big boy weighing in at 280 and wife is over 200, so I know I am asking a lot from the 103 engine. I believe it has the Stage 1 kit, Regardless, its a dog when trying to get it moving, a lot of throttle and feathering the clutch.

    Just wondering if I can change the front sprocket or rear sprocket to get a better rear ratio? Has anyone here done this? Or anyone here have the same issue? Thanks for all inputs. Kim

    Hi Kim, welcome to the forums from East Virginia.

    I had the same problem with my 2010 Triglide. I , along with several others have changed my front sprocket on the rear belt drive from a 32 to a 30 tooth. Made a world of difference starting off in first gear. Here is a VERY LONG thread from a few years ago that shows the process in detail.

    I had my Indie mechanic do mine since I don't have the tools for it. Search the forums for (30 tooth sprocket) and there is more info on it. The specs on a 2013 FLHTCU showed that you have a 32 tooth sprocket as stock.

    I would rather have the more power than higher RPM… I would put Andrews 48 cams and a good tuner in it.

    the one thing I don’t like on my 14 TG is the gearing.

    Did you ever get your sprocket changed out? Had you thought of changing the motor sprocket with a new primary chain instead of the trans sprocket?

    I've read some older posts and seen where Roadsmith had told them that there wasn't enough adjustment in the rear belt to allow for changing the trans sprocket.

    Did you change to a non-compensated sprocket, or did you find a compensated one? Read a post that stated the non-compensated sprocket causes a vibration in the drivetrain.

    The sprocket changed on mine was the engine sprocket. Also a factory trike from HD 2016. no prob with rear belt. Don't know about Roadsmiths. I remember i was thinking a 2 tooth difference, but the service guy (I trust) said to only go 1 tooth . Did so with an Andrews sprocket.
