Vibration comments

Is no one going to address the actual real reason for VTX vibration some worse than others due to having closer factory weight limits i.e. Engine balancing. No aircraft engine has bad vibrations due to tolerances on weight being a whole lot closer than autos. There's really only 3 ways to actually fix not mask. 1:Rubber or hybrid engine mounts cuz has solid mounts which transfer everything. 2: harmonic balancer like cars have. 3: rebuild engine hv engine blue printed, so know exact weights and stats, and balanced. Solid engine mounts why High Dollar, hd's, had vibration for 30yrs. My'06 1300c just got has only slight vibration so guess I got lucky. Ty baby Jesus!

Wobble?

What Wobble are ppl talking about on 1300's? Do all hv it? Is it only high speed, highway or city or both? I'm no motorcycle mech but am car mech and aircraft mech, so isn't wobble usually caused by bearings somewhere on motorcycles?

Yes, it's been hashed over almost 20 years ago when the VTX was first released in 2001. It's in our How To, Step-by-Step board

Yes, it's the steering head bearings on the 1300. The 1800 has a different type so when the 1300 owners starts to feel the wobble they swap out to the 1800 type

Thank you, Gabby Johnson, for this most recent example of Authentic Frontier Gibberish.
And welcome to the VTXOA.

Tires are the main cause of "wobble".
I had the good taper bearings on my 1300 and had a tire that would wobble when I let go at decel for a light or a stop sign.
Only once with one brand.

Vibration from a V-twin is normal.
Tuning will affect it.
I removed the stock mufflers and added JC whitney mufflers.
A weird vibration at 52 MPH made me want to puke.
My HK exhaust depending on what I do with the back pressure (lollipop) affects vibration.
Put your hand on the fuel tank and feel the vibes.
VTX engines have rotating balancing shafts. 1300 is single pin, 1800 has two pin crankshaft.
VTX 1300 rotating mass pix, crankshaft and balancers. A hefty crankshaft!
Latest spec I found was 41 lbs for the 1800 crankshaft.

Flat aircraft engines crankshaft have opposing pistons to minimize vibration.
