Bad rattling noise while going 40 mph and up

[given123]

While I throttle once my bike gets up to 40mph and as it goes faster the bike starts to make a rattling noise but only after I hit 40 mph or faster and while I'm holding 1/2 throttle or more

It's sounds like it's coming from the pipe side of the bike

Anyone know what it could be and I know it's not the pipe cause I tried 3 different pipes and it still makes that same noise

Does it only rattle when you're riding, or can you get it to rattle when it's on a stand with the rear wheel off the ground?

Can you figure out roughly where it's coming from?

My guess would be if it's related to going at certain speeds and not related to revs it wouldn't be an engine problem but maybe something in the wheels or rear gearing.
Possibly speedo cable?

Might be your center stand rubbing the exhaust. Had that problem also. Check it out

I agree with the exhaust note but could be the gasket going out? My pgo ticked til i replaced my exhaust gasket with a equal seal.


Doesnt tick now, does if it ticks at hitting the gas then thats the exhaust ring. At 40mph =leak
