Weird screaming noise

Anyone every hear a screaming noise in around there cluster.
Was out for 40 km and every time id wind it out in 5th it would sound like a bad horn noise. And when I come to a slow stop it would go away .
Did it a couple times .

 

It's most likely your speedometer. Mine is really loud when the temp drops below 50 degrees (f). In the summer, I rarely hear it. I've heard of quick fixes where you drill a tiny hole and shoot some white silicone grease in there. I don't have the courage to do it. I'm afraid that it will end up fogging the glass.

 

clean and lube speedo cable/ tach cable if you have one. or replace it , then clean and lube speedo and tach

 

see bigfitz write up on speedos

 

In my case, it is not the cable. I wish it was!

 

Ok thats What I thought .but I was alittle scared haha .Thanks guys .

 

Speedo and Tach dissection with pics

 

If you have an xj750 seca or maxim you can pull the cluster remove the back and the bracket and 6 or 8 screws separate the speedometer after removing 2 screws by the housing . Carefully take PB blaster or Silicone spray with a nozzle spray down into the pinion also flip it over spray around the neck where speedo cable attaches . Take a Q tip and a little grease on the gears . Be careful do not touch face you do not want finger prints and be careful do not touch needle as they can break easy . My speedo had done the same thing you describe and I had another cluster with pristine face plates but this one did same thing worked fine after my surgery so far so good. Good luck.

 

I get a scream , it comes from something between the handle bar , the saddle and the foot pegs.

There is a high pitched whining sound that comes from the fins at over 4k rpms.
