Do you have any suggestions to remove the vibration at 3500 RPM at speeds of 45-60 Mph?

The newer units from Givi use a couple of rubber O-rings where the two halves of the bar join up front. As I understand it, this was done specifically to prevent the buzzing and rattling coming from that part of the bars.

Make sure that the damper rod top mounting nut is tight. My car developed noise within a year, and I found loose nuts on both sides.

Sorry to say, but I think you have a bad motor. I would return it if possible or call Proform to replace it especially if you recently purchased it.

They sell a plug that reduces the rpms. I use one. So I am sure you could put a pot of some sort on it as well that would reduce them too.

I have not experienced any vibration, slight sound from the fan while running in the maximum speed.

Vibration shouldn't be there. Had no such issues with vibration and had the same setup installed for two years. Gonna have to say it was installed wrong or not aligned right.

Yes, but at some point soon it will start to rattle and drive you crazy. You also will need a speed reducer.

Regular tuning has worked thus far for me... If it's going to sit for a while, tuning it down may not be a bad idea.

My recommendation would be a variable power drill either corded or cordless that you can put a hose clamp on to vary the speed. They have a much greater range of variance without damage to the motor.

My Lactrical Alt. also has a vibration at rpm's below 2000, and under pull above 2000. have not noticed any extra heat, but haven't checked. The output is slightly above 14 volts.

I get vibration at low rpm, under load, on the throttle. Not noticable at constant throttle, cruising. I installed new rubber isolators and I am not 100% sure they are aligned properly. That might be the vibration, metal against metal within the drive hub. as to hot, measure the alternator body as well as the engine cassting ahead of it with an Infrared thermometer. Hot to human touch is only 45C, the Tstat is 95C.

They get pretty noisy at anything above 55 mph. Only recommendation would to not overfill them. They were tolerable up until I had them rotated and the shop overfilled them past the max psi.

My bet is that at higher speeds, it will throw off the balance of the wheel. Or should I say, the higher the speed, the more vibration will occur because of the weight.

I use this stuff in Lawn Mower tires so vibration is not a factor. I suppose if you installed globs of this stuff into vehicles tires and then ran them down the interstate you would wind up with tires out of balance and vibrations like crazy.

yep. I've found that a tiny adjustment to the resistance will make the noise go away. I think it's just a result of something rubbing on something else, probably will get smoother as you break it in.

I had same problem. I was using a 4000psi and it was like a flying saucer! Anyway it stopped spinning and I threw it on the bench and took apart bottom plastic bearing, cleaned it up a bit and tighten back up where it would spin freely by hand. it's kind of adjustable and it worked good again. Not that high of quality.

Stuff a little cotton in the intake. Most of the noise is from the intake chamber resonating.
