Bike shudders when I pull the clutch in and throttle off. Feels like it's sucking air somewhere. Anybody know where to look?

 

Believe me, I'm no fan of many HD dealer service departments, but here and there there's someone who actually knows what they're doing... I'm pretty sure there's a dealer right next to your indy shop... Since your guy Ivan isn't really a "Harley Specialist," and considering the long list of issues that you perpetually have, I wonder if it might make sense to have the dealer just go through your bike once...

I really try to do everything myself... I think the only things I've paid anyone to do on this bike are tire mounting, powder coating, head work, and cylinder honing. I completely understand not going to the dealer. But maybe one complete assessment of the overall state of things might make sense with your bike at this point...

Or not... I really don't know anything about the competency of San Diego HD or Ivan's Fast Bikes... It just seems like you never have any time where everything just works!

 

You may want to list what model bike and year it was produced...if you are on a touring bike it may have a different problem than say a dyna.

 

Dealer is a joke. I took it to the dealer and after two hours and $110, the diagnosis was "Normal". So I'm resigned to the fact that I have to diagnose and fix my own problems. Without expensive diagnostic equipment, it's just trial and error. The vibration is cured, but I had to find it myself. Now there's a major shudder when decelerating and something is banging when I hit a bump. Ivan must have left something loose when he installed the rear mount. The dearth of competent Harley mechanics is sad.

 

Am I remembering right that you recently had a front mount issue as well? It's possible that changing the mounts has resulted in the drivetrain sitting slightly differently in the frame, which may result in some interference somewhere when decelerating... A common point of contact is the sidestand pin and the frame crossover. You'll see what I mean if you look under the bike where the sidestand mounts. If the engine shifts forward slightly when braking, it can hit the frame causing a clunk. Or it could be in constant contact, causing vibration...

 

Replaced the front mount, but the rear mount was causing the vibration. '09 FatBob.

 

Since you're in San Diego, you might contact Lee's Cycle. They've been known to do decent work (especially suspension set-ups) for high performance machinery.

 

Another week...another drama

 

In the friction zone only, I assume? First thought is clutch judder. It may just need some exercise if it's been doing a lot of sitting. Would also double-check the adjustment and fluid level & type. Being a wet clutch it will behave differently with different fluid viscosities and friction specs in the primary.

 

Did. They don't work on Harleys.
