2009 HD Sportster Excess Engine Vibration

[@fernandoborja5259]

My 2008 Harley nightster is doing the same thing and at first I thought it was the motor mounts but apparently front and rear are still good

[@stevofish7]

Yep, it is normal per what everyone says. Depends on how much you can take it.

They all vibrating like that i can't see anything unusual...

[@stevofish7]

Yeah, come to realize they all do so at certain degrees of severity. I was really feeling it in the handlebars at idle. I traded her in for a true 1200 and the idle vibration and the ride is way better.

​@@stevofish7Hi, can you explain more what do you mean by "true 1200" just curious. Im new to Harley and my sportster shakes like yours

[@stevofish7]

The 2009 had the 1200 moniker on the air intake cover, but after reviewing the VIN, I discovered it was an 883. I had no idea if it ever was upgraded to 1200ccs by having the 1200 kit installed, but I kinda thought that may be the reason for the excessive vibrations if they did install the 1200 kit. I also replaced the front motor mounts, but that did not help. I had no idea about the Harley vibration issues until I got the 2009, but thankfully my current 1200 is much better and I'm enjoying the ride!

@@dawidgogacz Levels out at higher RPM. At least mine does. Their kind of hopped up, peaked cams. My plugs were white ( to lean on fuel ) A tuner ( Vance and Hines ) fuel pak 3 smoothed mine out a lot. 08 1200, goes like a raped ape.

To me it's running like the IAC control valve is plugged up. A good cleaning with Throttle body cleaner should solve that. Maybe 20 minute job on the high end. Lots of KZbin videss on how to do it. Two Wheeled Rocco has a good one.

Thank you for your suggestion!! I already tried that but maybe not thorough enough. I'll prob take the control valve off to ensure a good cleaning!
