When I get up to 60-65, it seems to be OK but after that, I start feeling my motorcycle vibrate more and my mirrors are even blurry from the vibration. It is just me or is this normal?

Sometimes the mounts are loose and it allows more vibration than normal. Dave

I ran the top mount single bolted for years. One in the engine (doesn't count) and the lower one in the frame, since the upper bolt interfered with my fuel tank.

Check the riser nuts under your top triple tree. The risers/bar "float" on rubber dampers that shrink as they age and dry out. Polyurethane swaybar endlink bushings can be shaved down into perfect replacements. But regular stock replacements are cheaper, less work and do the job sufficiently. Add an extra washer on the bottom side to draw them down a bit tighter as they shrink.

In general it's not the smoothest ride but single cylinder vehicles tend to have a bit of vibration so I don't sweat it. The speedo rattle bothers me a bit more and I might try to fix it one day.

I fixed mine not to long ago and it wasn't very difficult at all. I just put in rubber washers anywhere metal might hit or slap. There is a real good thread in the tech section. Probably a better & more permanent fix then what I did.

Yeah I've actually seen the thread and am just being lazy about it.

Once I start my longer rides next week I'll be using earplugs and then it's even easier to ignore and I'll probably continue being lazy. Grin

I got mirror rattling vibration at anything above 50mph.(The mirrors were useless). Also, it hurt my wrists it was so bad. After I balanced the rear wheel, the severe vibration stopped.

Line the balance dot up WITH the valve stem. Rarely needs additional weight that way. I've mounted and balanced thousands of street motorcycle tires. The ones that required a bunch of weight were always credited back by the distributors and replaced free of charge as they were "culls" that slipped through quality control checks.

Been in and out of the motorcycle business since I was 15 back in 1987. The front on Pokey was done in the back of my truck with a tire spoon and a flathead screwdriver, while Sam's rear tire was being fought with in a tire machine. I bet Pine is STILL traumatized by some of the words/phrases he heard that day... Roll Eyes

Yeah, the metzler me880's come with a red dot (heavy spot), that should be opposed to the stem.

That dot wore off after a couple thousand miles (I should complain!)

Anyway, I marked the stem location with chalk(this decision was ill advised), and then I pried the tire off. I used Windex to help lube the beads over the rim. Do you see where my plan started falling apart?

Anyway, to re-balance, I had to take the tire half off, mount the tire without the tube, find the heavy spot, mark it with paint, let the paint dry.

Then, tire half off, tube in, tire back on, pumped up, then balance with weights.

So easy. It only took me three weeks to balance a wheel. Embarrassed

I think my motorcycle is OK and balanced alright. I get a little vibrations but nothing major but I have noticed that sometimes when driving 60+ the mirrors seem blurry and even looking forward does too. Someone I know said it's probably my new motorcycle helmet and it's not aerodynamic as it should be. Any thoughts on that everyone? I've also been adjusting my windshield some and maybe that has something to do with it. Hmm...not sure now.
