Premium Member norcal616 Posted October 3, 2017 Premium Member Share Posted October 3, 2017 On my FJ-09 the OEM front sprocket caused clunky bass like vibrations when the chain makes contact with the rubber noise damping thingy...so my solution was to run a plain jane steel sprocket w/o the rubber noise damping thingy... now the vibrations are barely noticeable compared to the OEM front sprocket... my question is this, has any FZ-07 owners swapped the front sprocket with an aftermarket sprocket of same tooth count? I got one on order as well as a new rear sprocket and chain since they are 16k miles old, I would use the one from my FJ-09 for a few quick test rides but its one tooth smaller... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...
r1limited Posted October 4, 2017 Share Posted October 4, 2017 I will be going with a Vortex front rear 520 kit this winter. I notice no noise outside that ridicules 2 inch of slack “Laws that forbid the carrying of arms disarm only those who are neither inclined nor determined to commit crimes.” --Thomas Jefferson quoting Cesare Beccaria Link to comment Share on other sites More sharing options...
markstertt Posted October 9, 2017 Share Posted October 9, 2017 Running vortex 17/44 520 conversion from Bellisimoto....no issues and no slack with auto tensioner. May narrow stock 43t. rear down to 520 width to give 17/43 a try. It's nice to have first gear run out a little further. Link to comment Share on other sites More sharing options...
