n13ldo Posted August 30, 2018 Share Posted August 30, 2018 Hi Guys/Girls, So I'm a VFR nut. Started off on a VFR750F back in 1989 and have had 1 or 2 of every generation since. Currently own a VFR800Fi1 (see below - rear wheel from a 1994 VFR750) Recently I bought a 12k mile, 2015 non-DCT VFR1200F (still in Honda warranty with full service history). As title says, there is definite not normal engine vibration most noticeable (stationary) at 4-5k rpm. Took it to my favourite Honda dealer, they had it for a week and said everything is normal 'these bikes are a bit vibey' they said. I read a post on here about vibration and possible routes to go down are: - Clean the o2 sensors (I've bought a working used set and plan on giving them an ultrasonic bath) - Cleaning the fuel injectors. What's the recommend method of cleaning the fuel injectors? Thanks for reading ! Link to comment Share on other sites More sharing options...
andy Posted August 31, 2018 Share Posted August 31, 2018 Just read a write up on the new Indian V-twin that says it has rear cylinder deactivation “like the VFR-1200F.” The article points out that this feature prevents heat build up and may contribute to better fuel mileage. I don’t know if my ‘12 VFR12 has this feature, but could this be contributing to your vibration? Others have mention heat at the right foot. I’ve not experienced either the heat nor the vibration, but if my bike that’s this feature, it’s probably not working because I average about 39 mpg.

Mainer Posted September 3, 2018 Share Posted September 3, 2018 I had what felt like some extra engine vibration after my 28K mile service which was noticeable at idle on my 2012 VFR 1200. I took it back to the shop and they found an exhaust leak in a gasket right after the header pipe. They said it was a "small" leak. After they replaced the gasket, the bike was running like silk again. 🙂 Link to comment Share on other sites More sharing options...
Member Contributer BusyLittleShop Posted September 3, 2018 Member Contributer Share Posted September 3, 2018 Even though an 90º V4 sports perfect primary and second balances they still vibrate to some degree and the one thing to eliminate if you feel more vibrations is a loose exhaust system because it will amplify any of those vibrations to an annoying level... tap the pipes with the palm of your hand to test if any bolts points or connections are loose... also check the foot pegs bolts and anything bolted to the foot pegs...
